In-house Resources
Sheerframe Ltd is completely self-sufficient having in-house
toolmaking, product design, research and development and
testing facilities. Few, if any, UK-based extruders can boast
such extensive resources.
Many of the industry’s pioneering breakthroughs in the
past 35 years have originated through development of the
Sheerframe system, from widespread use of co-extruded
weatherseals and gaskets, to our current leadership in
sustainability technologies.
Specifiers have access to everything from Window Energy
Rating (WER) and Door Set Energy Rating (DSER) calculations
to security testing and full elevation and cross-sectional
drawing support to detail specific project designs.
Pedigree
Design
Sheerframe systems are designed to
offer specifiers the maximum choice
in window styles. Three core systems
provide an unsurpassed range of
window options, all engineered to
ensure ease of manufacture, efficiency
in use, longevity and optimum
weather performance.
Development
The Sheerframe brand has always
been at the forefront of PVC-U window
design technology. An ongoing
programme of product development
has included market leadership
in the introduction of lead-free
stabilisation and pioneering of Zero
Carbon technologies.
Production
Sheerframe Ltd’s production facilities
house state-of-the-art technology
for the design and manufacture of
window and door profile systems and
curtain walling.
ISO 9001 registered, Sheerframe not
only designs its own systems but it
also produces much
of its own tooling,
blends its own
material and applies
the most rigorous
procedures in extrusion, to maintain
total control over quality.
Sheerframe Ltd holds substantial
hardware and profile stocks and
runs its own delivery fleet in order
to ensure continuity of supply to its
network of approved Sheerframe
window and door fabricators.
Support
Sheerframe Ltd offers extensive
technical support to architects and
specifiers. A team of designers
and structural engineers, based at
Nether Heage, provides assistance
in the choice of appropriate window
styles, with line and general assembly
drawings available on CAD disk if
required.
Structural engineering data on wind
loading and load bearing capabilities
of both window and curtain walling
systems can be provided for individual
applications, using computer
programmes specially designed for the
Sheerframe system.

SHEERFRAME LTD
THE SPECIFIERS GUIDE
Sustainability
Sheerframe is the first calcium organic stabilized PVC-U
window and door profile system in the UK. Launched
in 2005, it leads the industry in the use of lead free
materials.
Its innovative multi chamber co-extruded profile design
– coupled with high performance hardware – creates
attractive, durable, energy efficient windows which truly
stand the test of time.
That means they deliver optimal sustainability – at least
35 years of service with virtually zero maintenance. And
at the end of their long life, Sheerframe windows are
designed to recycle easily, with no heavy metals.
One day, all windows will be made this way.
Sustainable solutions
The UK Government is legally
committed to a 34% reduction in CO2
emissions by 2020 and 80% by 2050.
Building Regulations changes will seek
to assist in making this happen by
calling for new homes to be built to
Zero Carbon Standards.
In addition, large-scale efforts are
underway to deal with the poorly
insulated housing stock especially the
solid wall properties of which 8 million
are estimated to require upgrading.
In addition to grant aided schemes,
ECO funding initiatives will seek to
improve the housing stock over the
next 25 years. Sheerframe windows
and doors are proven to make cost
effective performance benefits which
are Golden Rule compliant and which
achieve U-values down to 0.8W/m²K.
Top energy ratings under WERs to A+
and DSERs for doors also contribute to
savings and CO2 reductions.
2016 Building Regulations changes
require new homes to be between
55 and 60% better on heat loss or
CO2 emissions than the 2006 standard
(no worse than 10 KG CO2/m2/year
for detached houses) through fabric
improvements such as windows and
doors plus affordable housing solutions.

The window is balanced at all angles
and has a locking restrictor on both
the initial opening position and also
on the fully reversed position. The
hardware for a side reversible is
similar in operation but allows the
windows to be opened on a horizontal
axis. This gives over a 90 per cent
open area and is often used to achieve
compliance with fire regulations.

Top Reversible
Zero Carbon
The Sheerframe top reversible has the principal sections
designed with five independent chambers, trapping air
which acts as an insulator between the outside and inside
temperature environments. Most other systems are
either two or three-chambered and give inferior thermal
performance.
Five chambers help towards the energy requirements in the
Code for Sustainable Homes plus, combined with Thermlock
structural foam reinforcement AND a high performance
glazing specification, can achieve U values down to
0.8Wm2K. The Sheerframe Top Reversible is part of the
classified zero carbon window range.
Weather Tightness
Twin weather seals on the principal profiles are fused to the profile surface
and welded together, making a continuous homogeneous weather-tight seal.
◆ Window energy ratings for fully reinforced frames can
be as low as Category A (WER) depending on glazing
specification - glass can be 28mm double glazed or
triple glazed in 36mm or 44mm.
Levels of up to 1000 pascals on air and 600 on water tightness make
this reversible design far exceed any standard specification requirement,
keeping dwellings both drier and warmer than previous generations of
product have achieved.
Tested in accordance with BS6375 Part 1, the Sheerframe top reversible
routinely outperforms previous notions of air and water tightness.
Reversible window opens out like a
top-hung but looks like a vertical slider
and reverses out for cleaning.
◆ Gives strength and security without
compromising thermal efficiency
◆ 35% stronger than standard
aluminium on deflection strength
◆ Torsional rigidity many times better
than steel when compared to steel
open box sections
◆ 25% greater security – screw pick
up ridges make fixing easier.
Thermlock® delivers 25% greater
pull-out strength on handles, keeps,
shootbolts and hinge fixings
◆ Customer friendly – warm and clean
to the touch, Thermlock® is more
pleasant and safer to work with

Ventilation
A large range of ventilators are available to meet
the current Building Regulations, Part L/A Energy
Efficiency and Part F Ventilation.
Vents can be fitted through the outerframe or
casement, as well as overframe. Overframe
ventilation is a popular solution for newbuild
applications, and Sheerframe has an excellent
range, incorporating good air and sound tightness
when closed, as well as compliant ventilation
when open.

Regulations
Technical information
Composition
Ventilation systems are to be
constructed of PVC-U matched to that of the Sheerframe window system, or of proprietary products available in either aluminium or PVC-U.
Appearance
Due to the range of options available,
appearance can be altered to suit
specification requirements, by locating
the ventilator either over or through
the framing.
Size/Capacity
All Sheerframe ventilation systems are designed to comply with the
Building Regulations requiring a
minimum of 5000mm2 equivalent area
per habitable room.
Options
Sheervent is a specifically designed
ventilation system, to suit all styles of window. It allows up to twice
the requirements of the Building
Regulations, is visually unobtrusive
being placed on top of the window.
Built-in sound attenuation is also
available. As there is no integral
routing into the window system, this means that there is no possible
weakening or exposure to the
elements of the frame system.
Standard Ventilators
These are normally located either
through the outerframe or through the casement frame, to facilitate
ventilation. Various types are
available from Sheerframe. For further
designs and details, please contact the
Hardware Division.
Sound Attenuation
Special sound reduction cartridges can
be fitted to the aerated vent which
help achieve a weighted normalised
index of 38dB. Contact the Specifier
Support Department for the details of
Sound Attenuation Sheervent.
Building Regulations Part L/A
Energy Efficiency and Part
F Ventilation, England and
Wales, govern decisions on the
performance of ventilators. Under Part L/A, ventilators need to be efficiently air-tight when
closed because the maximum air
permeability of new dwellings is
