PRODUCT
PERFORMANCE
A. GENERAL PERFORMANCE CONSIDERATIONS
Pella ® windows and doors, are designed and manufactured to established engineering and industry standards which maximize satisfactory performance within the limitations of the specifications, conditions and tests listed.
Published air infiltration performance of other products, and Design Pressure (DP), Structural Test Pressure (STP) and water penetration performance numbers for all products are representative of test performance of product samples. Testing is performed on randomly selected production samples, and conducted in Pella’s test lab as well as in independent testing laboratories. Products which are
Hallmark Certified are noted on the product labels and in the Size and Performance Data charts in each product section of the
Architectural Design Manual.
Many products will exceed published specifications; however, performance of installed products may be affected by factors beyond
Pella’s control, such as shipping, handling, installation, construction practices, excessive environmental conditions, normal wear and tear and ongoing care and maintenance.
Although efforts are made to minimize the effects of such factors, it is not possible to guarantee that any particular unit will meet or exceed published specifications.
B. SEVERE CONDITIONS
Projects that will be subject to severe climatic and atmospheric conditions may require that architects and specifiers address higher product performance requirements and more stringent maintenance schedules.
Severe conditions that should be taken into account when selecting, specifying and designing to accommodate windows and doors may include:
Sand and Salt
Exposure
Chemical Exposure
Climatic Exposure
Areas of Severe
Wind and Rain
Any windows and doors installed near salt water — regardless of material or manufacturer — are subjected, with other building materials, to more severe weathering than in other typical locations.
Along with other building products, they should receive the additional protection which is standard and customary practice in such coastal locations at time of installation, and periodic inspection and maintenance as necessary thereafter.
Severe chemical exposure in locations near chemical plants and some types of industrial complexes may adversely affect satisfactory performance of Pella products and substantially increase maintenance requirements. Judgements regarding the use of Pella products in such areas should be based upon local experience and customer awareness. Pella products should not be used in indoor swimming pool or hot tub enclosures or other high humidity and corrosive environments.
Pella products are designed to perform in cold climate applications, however condensation or ice can form, mainly on interior glass surfaces, at low temperatures. Condensation or icy conditions will primarily depend upon the amount of room side humidity to which the products are exposed and generally does not indicate a product defect.
Areas subject to severe wind and rain may produce temporary conditions which exceed product performance standards. No claims are made beyond compliance with the product performance levels published for each product at the time of manufacture. Special design considerations may be required, such as subsills, built-up curbs, overhang protection, or unit set back from exterior face of wall.

Positive Interior Air
Pressure
Units Set at an Angle
Mullions should be designed not to exceed L / 180 deflection under design wind load pressures. Some conditions may require less deflection.
In addition, all installations, where there is a combination of vertical and horizontal mullions, will require reinforcement in either the horizontal or vertical direction. Some conditions may require additional horizontal mullion reinforcement to carry dead loads. See www.PellaADM.com for more information.
See www.PellaADM.com for stacking considerations.
For continuous horizontal rows of windows, a vertical expansion joint must be provided at least every
20' (6 096mm). See the PellaADM.com site for more information.
Pella units are not intended to provide the entire exterior surface or large expanses of a structure.
Combination assemblies are limited by horizontal and vertical structural mullion design and other installation factors. Installation applications beyond the criteria established in the Combination
Recommendation section must be designed and considered on a job-by-job basis and require factory shop drawings.
Because of special ventilating requirements or through natural stack action in some high-rise buildings, positive interior air pressures may cause between-glass condensation in winter (for Designer Series ® products with an interior hinged glass panel).
No Pella window or door products are to be installed at any angle from vertical, unless specifically approved by Pella Corporation.
E. SPECIAL REQUIREMENTS
Safety Glass
Interior Trim
Glass installation in areas subject to human impact must be safety-glazed according to the Safety
Standard for Architectural Glazing Materials (16 CFR 1201), issued by the U.S. Consumer Product Safety
Commission (or as prescribed by local codes).
Pella wood and aluminum-clad wood products are intended to be installed with interior wood trim or other trim that will cover the frame edge.

PERFORMANCE
ELEMENTS OF PRODUCT PERFORMANCE
Performance is an important criterion in the selection of windows and doors. In this manual, we refer to two types of performance: product performance and glazing performance. Product performance includes the following elements: Performance Grade (PG), Design
Pressure (DP), Performance Class, Water Penetration, Air Infiltration and Forced Entry Resistance (FER). A definition of each of these terms is below. Pella ® product performance can be found in each product section.
Glazing performance includes elements such as U-Factor, Visible Light Transmission (VLT or VT), and Solar Heat Gain Coefficient (SHGC).
Glazing performance information can be found in each product section.
PRODUCT PERFORMANCE TERMS

Forced Entry
Resistance (FER)
Numerical designator based on the lesser of Design Pressure (DP) and Water Penetration performance. In order to qualify for a given Performance Grade (PG), one or more representative samples of the product must pass all required performance tests for the products type, including operating force (if applicable), air infiltration, water penetration, Design Pressure (DP), Structural Test Pressure (STP), Forced Entry Resistance (FER), and all product specific auxiliary tests.
The industry standards define requirements for four Performance Classes of windows and doors. The
Performance Classes are designated: (R), (LC), (CW) and (AW). This classification system provides for several levels of performance so that the purchaser or specifier may select the appropriate level of performance depending on: climatic conditions; height of installation; type of building; window size; durability; etc. Product selection should always be based on the performance requirements of the particular project. For example, many residential buildings are built in locations subject to severe weather that may require higher performance fenestration products than those that meet only the Performance Class (R) requirements. On the other hand, many hospitals, schools, institutions, etc. may successfully use products meeting Performance Class (R), (LC), or
(CW) requirements.
A rating that identifies the load, induced by wind, that a product is rated to withstand in its end-use application.
Note: Design Pressure (DP) is not to be confused with Performance Grade (PG) or structural test pressure (STP).
A minimum of 1.5 times Design Pressure (DP). In order for a product to be rated at a given Design Pressure (DP), it must be able to withstand both positive and negative pressures of at least 1.5 times that of Design Pressure
(DP). For example, to receive a Design Pressure (DP) rating of 40 psf, the product must be able to withstand test loads of at least + / – 60 psf.
The ability of a window or door to withstand water leakage under specified conditions. It is a minimum of 15% of the Design Pressure (DP). For example, a product with a Design Pressure (DP) of 40 psf must pass a water test at a minimum of 6 psf. All products except side-hinged doors must never be tested at less than 2.86 psf.
The amount of air leaking through a window or door from exterior to interior. It is calculated in cfm per square foot of frame area at 1.57 psf (25 mph) or 6.24 psf (50 mph) wind pressure for all products.
The ability of a window or door in the locked position to resist entry under conditions of stress and load.
Products are given a Forced Entry Resistance (FER) grade; the higher the grade, the greater the ability to resist entry under specified conditions.
SOUND TRANSMISSION CLASS AND OUTDOOR-INDOOR TRANSMISSION CLASS
The ability of a window or door to reduce outside noise is an important consideration in product selection. The individual product sections display the actual performance ratings of Pella products including the Sound Transmission Class (STC) and Outdoor–Indoor
Transmission Class (OITC). Both measure the amount of noise reduction that can be achieved with a given product.
A noise reduction of 10 decibels represents cutting the noise level in half, as interpreted by the human ear. So a rating of 25 means that the product reduces the outside noise by approximately 25 decibels, cutting the noise in half 2-1/2 times, or cutting it by over
80 percent.
STC ratings give an indication of noise reduction that can be achieved with typical indoor (high frequency) noises such as human speech, computers, printers, etc. However, some specifiers and other manufacturers use STC ratings for exterior products because until recently, that is all that was available. OITC ratings are a much better indicator of exterior noise reduction. That is because OITC ratings include lower frequency noises such as traffic, construction equipment, and lawn and garden equipment, therefore, OITC ratings are usually a few points lower than STC ratings, because the lower frequency sounds are more difficult to attenuate.
Pella will continue to show both OITC and STC ratings until the entire industry begins to use OITC. In the meantime, when comparing to other manufacturers, be sure to compare apples-to-apples (e.g. STC vs. STC, not STC vs. OITC).

PRODUCT
PERFORMANCE
PRODUCT PERFORMANCE CONSIDERATIONS
Window or door specific performance requirements are determined from building code requirements, building location, topography, nearby structures, building design, placement of windows or doors, and other factors.
To evaluate whether Pella® products with non-impact or impact-resistant glazing meet specific project requirements, consider the first three criteria below, then determine joining mullion limitations for combination assemblies.
1. DESIGN WINDLOAD PRESSURE
Determine the design windload pressure for the application as specified by the architect, design professional and / or local building codes.
If no Design Pressure (DP) requirement was given, refer to ASCE 7
1
for an in-depth analysis of Design Pressure (DP) requirements for windloads on buildings. Contact your local Pella representative on projects over three stories.
Performance Class and Performance Grade (PG):
Use the Design Windload Pressure to select the Product Performance Class and Performance Grade (PG) per
AAMA / WDMA / CSA 101 / I.S.2 / A440.
Use the Design Data charts in each product section to ensure that the products and sizes you have selected meet or exceed the design windload pressure and Performance Class and Performance Grade (PG) requirements determined in this first consideration.
Glazing of Units
Once you have verified that the products / sizes selected meet or exceed the Design Pressure (DP) requirement, you must verify that the glass will also satisfy the Design Pressure (DP) requirement. If the glass will not be adequate, a stronger glass (for example, thicker and / or tempered) or impact-resistant glass can be requested in most cases.
Go to glazing section in this document for detailed instructions on how to determine glass thickness and / or type to meet project
Design Pressure (DP) requirements.
2. WIND-BORNE DEBRIS REGION
If the project is in a hurricane wind-borne debris region, protection from flying debris may be required (i.e., impact-resistant glass, storm shutters, plywood coverings, etc.). Check the local building codes for more information.
Pella HurricaneShield ® products with impact-resistant glass are available for these conditions. Check within each product section for specific products offering the impact-resistant glass option. Product approvals are listed on the Design Data pages within those same sections or at www.PellaADM.com.
3. PRODUCT APPROVALS
Some construction products need to be approved by the state, county, or other authority having jurisdiction. Consult local building officials and / or building design professionals for details.
Some examples of product approvals are:
FPAS — Florida Product Approval System
TDI — Texas Department of Insurance
NOA — Notice of Acceptance for Miami-Dade County, Florida
The approvals for select products are available from your local Pella sales representative.
DETERMINE JOINING MULLION LIMITATIONS (COMBINATION ASSEMBLIES ONLY)
When combining two or more units together to form a combination assembly, the mullion(s) must be analyzed for structural integrity. Use the project’s required Design Pressure (DP) to calculate when and what type of mullion reinforcement may be required for each combination. See the Combination Recommendations section.
When stacking units, weight limitations of the mullions must also be reviewed. See the Combination Recommendations section for more information.

PRODUCT
PERFORMANCE
This section explores requirements and limitations related to mulling various combinations of windows and doors.
IMPORTANT
Determining and meeting the structural load requirements and design of the rough opening is the responsibility of the architect or engineer. Window and door frame systems are not designed to support additional elements or components of the building wall system.
Specific accessories and construction details must address the various conditions that are critical for the proper design of a horizontal combination of windows (ribbon windows) and vertical combination (stacked windows) such as:
• Proper flashing
• Control joints to accommodate expansion and contraction
• Intermediate structural support
• Mullion reinforcing end anchorage
• Rough opening wall construction to accept loads transferred from the window combination.
DEFINITIONS
Combination
Combination
(Joining) Mullion
Composite
Integral Mullion
Reinforcing
Mullion
An assembly formed by two or more separate windows, window composites, or doors whose frames are mulled together using a combination joining mullion or reinforcing mullion.
A horizontal or vertical member formed by joining two or more individual window or door units together without a mullion stiffener.
A window or door consisting of two or more products in one frame utilizing an integral mullion.
A horizontal or vertical member which is bounded at either end or both ends by a crossing frame member.
A horizontal or vertical member with an added continuous mullion stiffener and joining two or more individual windows or doors along the sides of the mullion stiffener.
DESIGN CONSIDERATIONS
The following steps are provided as a guide to assist in properly integrating Pella ® products and accessories into combination assemblies. Sample calculations are based on the following steps.
1. CONSIDER THE OVERALL SIZE AND CONFIGURATION OF THE COMBINATION
The basic combination assembly types are shown on the following page. The dashed line indicates where a spread mullion or reinforcing mullion may be required. Windows or doors within the combination can be fixed or venting.
2. CONSIDER THE REQUIRED WIND LOAD (DESIGN PRESSURE (DP))
The Design Pressure (DP) is the wind load pressure that the window assembly must withstand. The Design Pressure (DP) should be determined by the project engineer or architect but can also be provided by the local code official.
ASCE 7-10, Minimum Design Loads for Buildings and Other Structures contains the generally accepted method for determining Design
Pressure (DP) for components and cladding based on building size and shape, geographical location, topographical factors, building use and location on the building's surface.
3. CONSIDER IF THE INDIVIDUAL WINDOWS AND / OR DOORS WITHIN THE COMBINATION MEET THE
REQUIRED DESIGN PRESSURE (DP)
Each Pella window and door is rated to withstand a certain level of wind loading. The Design Pressure (DP) determined in step 2 should also be used to specify window and door performance. The Product Performance Section provides more detailed information on the relationship between Design Pressure (DP) and the Performance Class and Performance Grade (PG) ratings used to specify window or door performance. See the Products section of the Architectural Design Manual to ensure that each window or door can withstand the required design wind load pressure.
4. CONSIDER IF THE GLAZING WITHIN EACH PRODUCT CAN WITHSTAND THE REQUIRED DESIGN PRESSURE (DP)
ASTM E 1300 requires that glazing be of adequate strength to resist excessive deflection under wind load. The Glazing Performance
Charts in this document, contains glazing Design Pressure (DP) charts. Select the appropriate glazing type and / or thickness required to meet the Design Pressure (DP). Pella sales representatives can utilize the Pella quoting system to determine the glazing Design Pressure
(DP) of a specific product.
Pella 2016 Architectural Design Manual | Division 08 – Openings | Windows and Doors | www.PellaADM.com

PRODUCT
PERFORMANCE
5. CONSIDER IF THE COMBINATION WILL BE FACTORY ASSEMBLED OR NON-FACTORY ASSEMBLED
Use the combination size tables found in the Installation Systems section to determine if the combination is available factory assembled.
If the combination is not found in the size tables, it is not available assembled from the factory. In this case, the non-factory reinforcing mullion table must be used. Also consider factors such as installation method, handling and accessibility to the opening. Conditions specific to the project may require a combination be assembled in the opening, or separated into multiple combinations.
6. CONSIDER THE REQUIREMENT FOR SPREAD OR REINFORCING MULLIONS
Placing windows and doors in combination creates joints or mullions that may need reinforcing. Spread mullions can also be utilized to achieve an aesthetic element. In order to ensure that a given combination will withstand the Design Pressure (DP) determined in step 2, use the reinforcing mullion tables in the Installation Systems section. These tables are organized by joint type and assembly type (factory vs. non-factory assembled). Use the graphical representation of each joint type to determine which joint type(s) are contained within the combination. The reinforcing tables consider structural performance only. Performance Class and Performance Grade (PG) ratings apply to single units only. See the Size and Performance Data page within each product section for more information. Also consider the tables for dead load when placing windows or transoms over awnings or doors.
7. CONSIDER THE APPROPRIATE MULLION REINFORCING
The reinforcing mullion tables on www.PellaADM.com are intended to aid in the selection of reinforcing members to help the combination resist the forces placed upon it by wind loads and loads caused by other units within the combination. Refer to the Installation Systems section for instructions on how to specify the correct reinforcing for the window or door combinations. If spread mullions are desired for aesthetic reasons, use the tables to determine if the spread mullion meets or exceeds the required Design Pressure (DP).
8. DETERMINE IF SUBSILL IS REQUIRED
Subsill systems that weep incidental moisture to the exterior are recommended for water management in openings where the potential for water infiltration is increased and may not be adequately managed by the building weather barrier, flashings and drainage system. Sample conditions include, but are not limited to increased level of exposure due to multi-story construction, high weather exposure, difficulty recaulking, non-standard installation methods, or when there are multiple units joined within the opening.
9. DETERMINE ROUGH OPENING SIZE DATA
The Installation Systems section contains recommendations for each installation type. Use the recommendations in this section to determine rough opening clearance dimensions as well as if subsill, frame expander, or expansion mullion accessories are required.
More information on Pella ® accessories can be found in Installation Systems section on www.PellaADM.com. Add any applicable frame, accessory, and mullion dimensions to arrive at the overall opening dimensions.

USE AND INSTALLATION CONSIDERATIONS
The following notes are important considerations regarding the use and installation of Pella ® products. Should you have any questions regarding the use and installation of any Pella products, contact your local Pella representative.
REQUIREMENTS FOR COMPLYING WITH APPLICABLE BUILDING CODES
Regulations governing the design and use of glazed windows and doors vary widely. The building owner, architect, contractor, installer and / or consumer are responsible for selecting products which conform to all applicable laws, regulations and building codes.
Pella Corporation accepts no responsibility whatsoever for failure of building owner, architect, contractor, installer, and/or consumer to comply with all applicable laws, ordinances, safety and building codes. Pella Corporation shall not be responsible for windows and doors, not installed in compliance with applicable laws, codes, or other regulations.
GLAZING AND SAFETY GLASS
Pella products are standard-glazed to withstand a minimum of 20 psf Design Pressure (DP). Specific code requirements, windloading and / or design specifications may require special glazing.
Unless specifically noted or ordered, Pella products are not provided with safety glass. Glass installed in areas subject to human impact must be safety-glazed according to the Safety Standard for Architectural Glazing Materials (16CFR 1201), issued by the U.S. Consumer
Product Safety Commission or as prescribed by other building codes.
REQUIREMENTS FOR PROPER INSTALLATION
All detail representations in this manual only pertain to the use of Pella products manufactured by Pella Corporation and are strictly limited to the published specifications and to the use of Pella products. Details shown herein illustrate typical general methods of installing Pella products manufactured by Pella Corporation and are to be used as guidelines only. Refer to the appropriate installation instructions and/or installation shop drawings.
The performance of any building is dependent upon the design, installation, and workmanship of the entire building system. Pella
Corporation strongly recommends consulting an experienced architect, contractor, or structural engineer prior to installation of
Pella products.
The individual (building owner, architect, contractor, installer and / or consumer) responsible for the project must take into account local conditions, federal, state, and local building codes, inherent component limitations, the effects of aging and weathering on building components, and other design issues relevant to each project.
Over time, all window and door systems may have some water infiltration; it is important that the wall system be designed and constructed to properly manage moisture. Pella Corporation is not responsible for claims or damages caused by unanticipated water infiltration; deficiencies in building design, construction and maintenance; failure to install Pella products in accordance with Pella approved methods; or the use of Pella products in systems which do not allow for proper management of moisture within the wall systems. The determination of the suitability of all building components, including the use of Pella products, as well as the design and installation of flashing and sealing systems are the responsibility of the building owner, architect, contractor, installer and / or consumer.
Consult with your local Pella representative on large and / or complex installations.

NOTE ON BARRIER WALL SYSTEMS
EXTERIOR INSULATION AND FINISH SYSTEMS (EIFS) AND OTHER NON-WATER MANAGED WALL SYSTEMS
Significant concerns have been raised regarding moisture problems including unacceptable water infiltration associated with the use of barrier wall systems which do not allow for the proper management of moisture within the wall system, such as EIFS (also known as synthetic stucco) and other stucco-like systems (sometimes referred to as “hard coat” or “one-coat” stucco) that use EIFS like coating systems, but omit the foam board. Specifically, a large number of EIFS installations, as well as other barrier type wall systems, have been found to have problems with excessive moisture in the wall cavity. The basic problem is that barrier systems do not account for the fact that moisture can—and will—penetrate the exterior wall surface. Once moisture penetrates a barrier wall, it remains trapped inside the wall cavity, where it may damage and even rot sheathing, framing and other moisture-sensitive building elements. In a large number of cases, the moisture problems have caused deterioration serious enough to require extensive repairs.
These problems often show up where there are penetrations in the building’s exterior, such as at windows and doors, however moisture problems are not limited to these areas. It is generally agreed that the root cause of barrier-system moisture problems is the inability of such systems to allow moisture that should be expected in any building exterior system to weep or evaporate to the building exterior, and that the problems are not caused by the penetrating components themselves, whether they are windows, doors, decks, or other features. As a result of these problems, except in extremely arid climates, barrier-type systems are not recommended over wood frame construction or over any other substrate that could be adversely affected by moisture.
Pella Corporation will not be responsible for claims or damages caused by anticipated or unanticipated water infiltration, deficiencies in building design, construction, and maintenance, failure to install Pella products in accordance with approved methods, or the use of Pella products in systems, such as barrier wall systems, which do not allow for the proper management of moisture within the wall system. Pella products should not be used in barrier Exterior Insulation and Finish Systems, (EIFS) (also known as synthetic stucco) or other non-water managed systems. Except in the states of California, New Mexico, Arizona, Nevada, Utah and Colorado, Pella makes no warranty of any kind on and assumes no responsibility for Pella windows and doors installed in barrier EIFS. In the states listed above, the installation of Pella Products in EIFS or similar systems must be in accordance with Pella’s instructions for that type of construction. Contact your local Pella representative for considerations with non-water managed wall systems and on large or complex installations.
Moisture infiltration problems in any type of building can be reduced by proper flashing and/or sealing around all building penetrations, including windows and doors. Proper flashing under and around window and door openings can reduce moisture problems in barrier systems, however the performance of any building system is also dependent upon the design and workmanship of the entire building system, which must take into account local conditions, climate, building codes, inherent component limitations, and the effects of aging and weathering on building components. Even when general installation recommendations are made by Pella Corporation, the determination of the suitability of all building components for each project, as well as the design and installation of flashing and sealing systems, are the responsibility of the architect, contractor, installer, and/or the manufacturer of the exterior finish system specified for the project.

PRODUCT
PERFORMANCE
There are several elements of glazing performance, including U-Factor, Visible Light Transmission and Solar Heat Gain Coefficient. Definitions of the glazing performance elements discussed in this manual are below.
Glazing performance data is based on the WINDOW 5.2 and THERM 5.2 computer programs for analyzing energy performance. WINDOW and THERM software are the latest technology in simulating energy performance. When comparing performance with other manufacturers, it is important to verify how the values were determined.

RESISTANCE
The temperature on the inside surface of the glass at the center of the glass. It is based on an outside temperature of 0° F, inside temperature of 70° F, and an approximate 15 mph outside wind.
Room side barriers to interior air flow (blinds, shades, drapes, screens) tend to lower inside glass surface temperature and humidity levels at which condensation occurs. Outside screens tend to raise inside glass surface temperature and level of humidity at which condensation occurs.
The actual amount of heat energy (BTU per hour-sq.ft.) that enters a room through a glazing system
(Assumes typical daytime summer conditions of 89° F outside and 75° F inside). The lower the value, the better the unit keeps out heat energy.
The amount of solar heat that passes through a particular glazing system divided by the amount that passes through a single piece of 1/8" thick clear glass (Assumes 89° F outside and 75° F. inside). The lower the value, the better the glass keeps out solar heat.
The amount of solar heat that enters a room through a window or door (total unit) or glazing system
(center-glass), divided by the amount that is actually contacting the exterior of the unit (Assumes 89°
F outside and 75° F inside). The lower the value, the better the unit or glazing keeps out solar heat.
The rate of heat transfer (BTU per hour-sq. ft.) through a window or door (total-unit) or glazing system (center-glass) (Assumes 0° F outside at night with an approximate 15 mph wind and 70° F inside). The lower the U-Factor, the better the insulating properties of the unit or glazing system.
The percentage of ultra violet rays that enter a room through the glazing system. It is a predictor of potential fading damage. Lower percentages indicate less fading potential (UV rays are those with a wavelength ranging from 0.30 to 0.38 microns).
This function, developed by Lawrence Berkeley Laboratories, is another way of expressing UV
Transmission. It is a better predictor of potential fading damage than UV Transmission. Lower values indicate less fading potential.
The LBL Damage Function is a weighted value, which takes into account that as the wavelength of the UV rays gets shorter, the fading damage potential increases. Therefore, two glazing systems with the same UV Transmission may have different LBL Damage Function values because one allows more shorter wavelength rays to pass through than the other.
The percentage of visible light that is transmitted through the window or door (total-unit) or glazing system (center-glass).
A relative indicator of a fenestration product’s ability to resist the formation of condensation at a specific set of environmental conditions. The higher the Condensation Resistance value the greater the resistance to the formation of condensation. Actual condensation performance is a function of temperature, humidity and air movement. For more information see NFRC 501-2010, “User Guide to the Procedure for Determining Fenestration Product Condensation Resistance Rating Values”
Total-unit values can be found in the individual product sections.

PERFORMANCE
Pella offers a variety of glazing systems and options for optimal design, performance and budget flexibility.
Please visit www.PellaADM.com for complete product glazing information.
GLAZING TYPE
Dual-Pane
Insulating Glass
Standard insulating glass consisting of two panes of glass creating an insulating sealed gas space.
Triple-Pane
Insulating Glass
Designer Series®
Triple-Pane Glazing
Insulating glass consisting of three panes of glass that create two sealed insulating gas spaces.
INSULATED GLASS OPTIONS / LOW-E TYPES
Advanced Low-E Pella's standard Low-E coating that is commonly used in locations with hot and cold weather extremes. Features insulating glass with a Low-E coating to increase comfort year-round while blocking 84% of the sun's ultraviolet rays helping to protect your home from fade damage. Advanced Low-E has SHGC significantly lower than clear glass or
NaturalSun Low-E. It is a good general purpose coating.
SunDefense™
Low-E
This product combines a Dual IG with an extra hinged glass panel to achieve thermal performance comparable to triple
IG. The interior air space is not sealed to allow for Designer Series® between-the-glass accessories to be installed or removed.
AdvancedComfort
Low-E
Commonly used in locations needing superior solar protection, high levels of energy efficiency and year-round comfort.
Features insulating glass with a special SunDefense™ Low-E coating that reflects more of the sun's heat to help keep your home cooler in the summer. SunDefense™ is recommended in southern climates and in more northern regions where there is a significant amount of direct sunlight. This may be on un-shaded east or west exposures, especially if the windows are looking over a body of water and there is no shade or overhang. SunDefense™ Low-E blocks 94% of the sun's ultraviolet rays has a very low SHGC while maintaining a clear unfiltered view.
Commonly used in locations in need of minimal winter heat loss and reduced solar gain. Includes the advantages of
Advanced Low-E plus further improvement in insulating performance (lower U-value) through an additional Low-E coating on the insulating glass. This low-E glass has the lowest U-value of all Pella’s dual glazed offering and is a good selection for customers wanting to meet the more stringent requirements of some local energy codes.
NaturalSun Low-E
ADDITIONAL GLASS OPTIONS
Obscure Glass Commonly used in intimate spaces such as the bathroom and bedroom. Creates privacy while allowing natural light to enter. Available in a variety of textured surfaces, will let sunshine in to increase comfort. Thermal and SHGC of obscure
IG is equal to clear glass when combined in IG with the same Low-E coatings.
Tinted Glass (Bronze,
Gray and Green)
Commonly used in locations where maximum solar heat gain is desired. This would be intended for Canada and the far
Northern regions of the US. It may also be used in regions further south if the home or landscape is designed to provide summer shading on the windows. This coating would be considered the best choice for “Passive Solar” homes. You may consider putting NaturalSun on the southern exposed windows while using Advanced Low-E on the other sides of the home. There is a slight visual difference with the different coatings, but if one is looking out at different directions in the room this should not be noticeable.
Spandrel Glass
Commonly used in rooms that receive a lot of sun exposure. Like sunglasses, windows with tinted glass block the sun's rays, so they're useful in controlling glare; plus, they keep rooms that get direct sun cooler. The tint also helps block the view into a home.
Commonly used between sections of a building including the area between floors, columns, ceilings, and other small or large spaces. The main aesthetic purpose of spandrel glass is to create an overall uniform appearance. Spandrel is created using fired-on frit methods. This process includes a ceramic frit that is fused to the glass using high-heat fusing methods. This technique creates a glass that will not fade over time. In addition, spandrel is up to five times stronger than annealed glass.
Laminated Glass
Impact-Resistant
Glass
1
Commonly used in locations in need of added security, ultraviolet (UV) protection and noise reduction. A polymer layer sandwiched between two layers of glass that cuts outside noise and harmful UV rays and offers added protection against intruders and forced entry. The interlayer holds the glass together if it's shattered.
Available in Hurricaneshield® impact-resistant products, commonly used in locations that endure hurricane-force winds or where additional security or noise reduction is desired. An advanced polymer layer is sandwiched between two layers of glass, offering strong protection from flying debris - while increasing the safety, security, ultraviolet protection and energy efficiency of a home.
GAS FILL / HIGH ALTITUDE
Argon
Krypton
High altitude
High altitude with Argon
Argon gas is commonly added to insulating glass assemblies to improve the insulating performance.
Krypton gas is added to insulating glass assemblies to improve the insulating performance.
For locations at high altitude the air filled insulating glass assembly is typically vented to prevent over pressurization of the system.
For locations at high altitude this product is a sealed, argon filled, insulating glass. The unit is manufactured at a pressure level tailored for the target elevation.
NOTE: Any product with argon and Low-E is referred to as Insulshield (1) Impact-resistant insulating glass is made up of a sheet of tempered glass combined with a sheet of laminated glass. For best performance, the laminated glass may be the interior or exterior pane of insulating glass, depending on the product.

PERFORMANCE
®
The impact-resistant glazing incorporated into HurricaneShield impact-resistant windows and doors is a high-performance, laminated glass with either
SentryGlas® Plus (SGP) technology from DuPont® or PVB technology, also from DuPont. This laminated glass is designed to offer outstanding protection to keep the glazing intact after the glass is impacted by hurricane wind-driven flying debris, as tested per industry standards listed below.
SGP has a laminate interlayer made from an advanced material called ionoplast. SGP is much stronger than PVB.
PVB is a DuPont Butacite® polyvinyl butyral laminate traditionally used in automotive windshields since 1938.
Pella’s HurricaneShield impact-resistant products are designed and tested to meet or exceed many but not all Gulf Coast and Atlantic Coast hurricane building code requirements. Pella has HurricaneShield impact-resistant windows and doors approved for use in Miami-Dade County, Florida as well as other areas along the Gulf and Atlantic Coasts.
HurricaneShield impact-resistant windows and doors are tested to numerous industry standards consistent with the intended application. These standards include:
ASTM E1886-13a (and previous versions)
ASTM E1996-14a (and previous versions)

PERFORMANCE
Pella’s unique between-glass Slimshade® blinds and cellular fabric shades improve window performance. In addition to reducing fading damage to interior furnishings, between-glass accessories enhance thermal performance of the window or door. When the Slimshade blind or cellular fabric shade is in the closed position, the U-Factor and shading coefficient are significantly improved (reduced).
Although operation of Slimshade blinds and cellular fabric shades is simple, the analysis of the heat transfer through a window or door with a betweenglass accessory is very complex. There is currently no industry-endorsed simulation tool that can be used to analyze the performance of Slimshade blinds or cellular fabric shades.
Pella has conducted independent tests, using NFRC methods. Results are below. All values shown are for 25" x 59" Designer Series® casement window.

PRODUCT
PERFORMANCE
The average barometric pressure decreases as the elevation above sea level rises. When standard insulating glass manufactured at one altitude is shipped to a higher altitude, the decreased air pressure will cause the glass to deflect. The amount of glass deflection depends upon many factors, such as glass thickness, air space width, air space temperature, difference in altitude, and size of the piece of glass.
The best way to avoid insulating glass deflection in high altitudes is to specify Pella’s optional high altitude glass when needed. High altitude glass has a hidden capillary tube installed that serves as a “breather”, allowing the air between the two pieces of glass to equalize with outside air in high altitudes. High altitude insulating glass does not contain argon. Therefore, use the following guidelines to determine when high altitude glass is required.
Example: A residential home is 7,000 feet above sea level. The product to be used in the home is Architect Series® casement windows with 5/8" insulating glass. Frame sizes of the units are as follows:
17" x 17" and 29" x 47"
To determine if high altitude glass is needed, you must first convert the frame sizes to glass sizes. The glass-to-frame difference for casements is 5". So the glass size of the units listed above are:
12" x 12" and 24" x 42"
The shortest glass dimension of the first size is 12". According to the chart below for 5/8" glass, the altitude limit for this size is 5,000 feet. Since the home is at 7,000 feet, you must order high altitude glass for this size of unit. The second size has 24" as its shortest glass dimension. According to the chart, it has an altitude limit of 7,000 feet, which is the same altitude of the home, so you do not need high altitude glass for this size of unit.

PRODUCT
PERFORMANCE
Certain Pella products with insulating glass use argon gas in the sealed air space to improve the insulating value of the glazing. The following paragraphs explain argon filling and how argon dissipates over time.
Using available argon filling equipment, it is not possible to achieve 100% argon filling. Insulating glass size, geometry, addition of internal grilles, etc. also influence the effectiveness of the argon filling process. For example, grilles inside the airspace contain air, and the air in the grille, if not completely removed, will reduce the overall initial argon percent fill level.
Since argon makes up approximately one percent of the normal atmosphere, the higher concentration of argon in the sealed unit is a driving force that causes the argon to slowly permeate through insulating glass edge seals to the ambient atmosphere. This driving force is present in all insulating glass with argon units regardless of which manufacturer produced them. Likewise, there is a similar driving force causing air (O 2 and N 2) to permeate into the insulating glass unit.
When argon permeates through the seal system of insulating glass units, the U-Factor will slightly increase (a reduction in thermal performance). The following are total unit U-Factor (as determined by the LBL WINDOW and THERM Computer Programs) for a typical casement unit at various argon levels:
As can be seen by this data, the increase in U-Factor is minimal when argon levels are decreasing by one percent per year. For instance, for an initial argon level of 90%, the total unit U-Factor would be 0.37. If there were an argon-air exchange of one percent per year, in 20 years the argon level would be 70%, giving a total unit U-Factor of 0.38.

Pella’s insulating glass with argon is available in most standard Pella products. See your local Pella representative for more information on this energy-efficient glazing option.
Pella Corporation warrants that its insulating glass with argon is NFRC compliant only at the time of manufacture. Pella Corporation makes no warranty regarding the rate of dissipation of argon or the amount of argon remaining in the window over time.

Use the glass charts on the following pages to verify that the glass thickness of a unit will meet the specified design pressure. These charts show required nominal thickness of rectangular plate, float and sheet glass, based on minimum thickness allowed in ASTM E 1300-04 (Contact your local Pella representative for performance of glass types and thicknesses not shown).
The charts are set up for single-pane annealed glass, so there is a multiplying factor for heat-strengthened and tempered glass, as well as sealed insulating glass. These factors are listed below:

(1) Interior hinged glass panels must be glazed to the appropriate single-pane requirement.
Factors only apply if both panes of the insulating glass are equal in thickness and tempered.
Example: Determine if 2.5mm annealed insulating glass will work for a 41" x 53" (frame size) clad casement with an established design pressure of 28 psf (1.34 kPa).
1. Determine the glass area of the unit. If the frame size is 41" x
53", and the frame to glass difference for clad casements is
5", then the glass area of the unit is 36" x 48". (Frame to glass formulas can be found in each product section.)
2. Use the 2.5mm chart—intersect the short glass side value (36") with the long glass side value (48"). Draw a diagonal line from
0.0 through that intersection point. Use the diagonal line to interpolate between the load contours. In this case, the interpolated non-factored load is 1.13 kPa.
3. Convert results to lbs / ft 2 (1kPa = 20.9 psf)—
(1.13 kPa x 20.9 psf) / 1 kPa = 23.6 psf.
4. Since this example uses annealed insulating glass, multiply 23.6 psf by the factor listed above for annealed insulating glass—
23.6 psf x 1.8 = 42.5 psf (2.03 kPa).
The calculated number of 42.5 psf is greater than the design pressure requirement of 28 psf. So this unit passes the ASTM standard for glazing design.

PRODUCT
PERFORMANCE
Under AAMA / WDMA / CSA 101 / I.S.2 / A440-08, window and door performance is classified using three primary designators: Product Type, Performance
Class and Performance Grade. In order for a product to meet a given performance class and/or grade, a number of requirements must be met. The following tables are intended to provide an overview of those requirements.
For example, to achieve a C-R50 (Performance Class R, Performance Grade 50) rating, a casement with a minimum frame size of 24" x 60" must surpass all of the air, water, structural and hardware sub-requirements pertaining to that class and grade.
To assist in selecting Pella products that meet project requirements, each product section in Volume 2 contains a product selection guide and design data tables which gives an overview of the class and grade ratings achieved as well as the rating achieved for each standard size.
Refer to AAMA / WDMA / CSA 101 / I.S.2 / A440-08, for a complete understanding of all performance requirements.

HALLMARK CERTIFICATION
The WDMA Hallmark Certification Program provides specifiers a method of identifying windows, doors and skylights that are manufactured in accordance with WDMA standards. The WDMA Hallmark is considered a mark of excellence among architects, contractors and other specifiers and is accepted industry-wide. WDMA Standards are referenced by HUD / FHA in their Minimum
Property Standards and by many other government agencies in their construction specifications.
Hallmark Certification verifies conformance with AAMA/WDMA/CSA 101/I.S.2/A440-08 and AAMA/WDMA/CSA 101/I.S.2/A440-11, and is determined by in-plant inspection of the manufacturing facilities and by sampling and testing of product.
Many Pella products are Hallmark Certified and are clearly labeled with performance class and grade information. Refer to pages C-20 through C-22 for more information about performance class and grade. General performance class and grade information is found in Volume 2 under each product section titled Product Selection Guide—Size and Performance Data. Individual unit class and grade ratings are found on the Design Data pages in each section. For additional information about the Window and Door Manufacturers Association, contact:

NFRC RATING
The National Fenestration Rating Council (NFRC) develops and administers energy-related rating and certification programs and their goal is to serve the public by providing fair, accurate, and credible information on fenestration performance. Pella products labeled with the NFRC
Energy Performance label are rated in accordance with NFRC standards. This allows for direct comparisons with other NFRC labeled products.
NFRC ratings are based on a combination of computer simulations and physical testing of product samples. For details go to www.NFRC.org.
