Wausau unveils INvent.PLUS windows with composite framing
New AW-100 Class windows offer R6 performance
Wausau, Wis. (Nov. 2013) -- During the 2013 International Greenbuild Conference, Wausau Window
and Wall Systems will debut its new INvent.PLUS™ Series windows meeting European benchmarks
for thermal performance, while responding to the North American aesthetic for clean style and narrow
sightlines. The innovative, composite framing delivers R5 performance for operable units and R6 for
fixed windows to support buildings’ goals for energy efficiency and occupant comfort.
“This no-compromise product incorporates a variety of engineered polymers, as well as aluminum
extrusions, each where the inherent materials properties are best suited,” says Wausau’s vice president
of technical services, Steve Fronek, P.E., LEED® Green Associate. “Low U-Factors allow broad
expanses of vision glass to meet Model Energy Codes and triple insulating glass further enhances
thermal performance. Too often in the past, best-in-class U-Factors required the designer to accept
bulky, wide or non-co-planar profiles. INvent.PLUS Series windows are both energy-efficient and
appealing to U.S architectural tastes.”
INvent.PLUS windows’ composite framing combines 55% engineered polymers and 45% aluminum
extrusions by volume. The aluminum contains recycled content averaging 70% or greater. The 311/16-inch frame depth incorporates several new energy-saving features: custom-designed 44mm
polyamide thermal barriers from Technoform Bautec, convective baffles and foam cavity fillers,
combined and optimized using both European and North American finite element thermal modeling
software tools.
Thermal performance, natural light, outside views, condensation resistance, low-emitting materials,
durability and recycled content are all attributes of INvent.PLUS windows that may aid buildings
seeking certification under such programs as the U.S. Green Building Council’s LEED Green Rating
Systems. For more than 30 years, Wausau’s experienced staff has provided products and support
services to meet projects’ energy and environmental objectives, including dozens of LEED-certified
buildings.
Within Wausau’s LEED-Silver certified manufacturing center, quality-controlled, factory fabrication
and glazing ensure real-world performance equal to the laboratory. INvent.PLUS high-performance
windows are pre-engineered and factory-glazed as part of the Advantage by Wausau® standard
product offering. Available on an accelerated delivery schedule, these competitively priced windows
are backed with an industry-leading warranty of up to 10 years.
Rated as American Architectural Manufacturers Association (AAMA) AW-100 Architectural
Performance Class, the windows are tested for 0.10 cfm/sqft air infiltration, 15 psf static and cyclical
water resistance, and structural integrity. INvent.PLUS windows can achieve a Condensation
Resistance Factor (CRF) as high as 83 per AAMA-1503 and a U-Factor as low as 0.16 BTU/hr.sqft.ºF
per the National Fenestration Ratings Council’s NFRC 100 standard. Sound Transmittance Class
(STC) ratings of 34 to 41, and Outdoor-Indoor Transmission Class (OITC) ratings of 28 to 35, provide
occupants with quiet interiors, which are especially important in health care and educational
applications.
Complementing curtainwall and storefront systems, INvent.PLUS windows have a 1-inch exterior
glass offset and narrow sightlines. Operable windows are offered as in- or out-swing casements, tophinged, hopper or awning vents. Punched openings, ribbon windows or full-height window wall also
are available.
Carrying triple glazing with ease, operable units feature heavy butt hinges or concealed stainless steel
four-bar friction hinges. Integral between-glass blinds manage light and glare, while minimizing
maintenance. Exterior muntin grids and panning systems with “T” mullions also are popular options
for renovation projects.
Frames, panning and muntin grids may be finished with liquid paint, powder coatings or anodize.
Dual-color finishing can be accommodated to match different interior and exterior color schemes.
With a palette exceeding 30,000 color choices, painted finishes may be requested with ultra-low
volatile organic compounds (VOC) and VOC-free content. Durable, VOC-free anodize finishes also
may be selected, including a patina-free copper.
