What
does the Kitemark mean?
Reassurance
The Kitemark is one of the most well known and respected product certification
marks in the world and is your reassurance that BSI has checked that
your window complies with the latest British Standards.
Product
Quality
Kitemark certification is voluntary and companies are not obliged
to join. However those that do are making a public commitment to the
quality of their products.
Confidence
Companies who have the Kitemark have confidence in their product.
They are required to give BSI unrestricted access to their offices
and factories and allow random samples to be selected for resting
on a regular basis.

Schemes for PVC-U Windows
There
are a large number of British Standards applicable to PVC-U windows
and related components. However not every standard has an associated
Kitemark scheme.
If you are buying PVC-U windows the
Kitemark to look for are:
BS-7412
– This is the primary standard for PVC-U Windows and covers
weather performance and durability along with a basic level of burglar
resistance.
And
BS-7950
– This standard covers a higher level of burglar resistance.
Other Kitemarks you may see are listed
below:
BS-6206
– This applies to Safety Glass, which must be used in areas
vulnerable to accidental breakage (your supplier should be able to
provide guidance on the use of safety glass).
BS-5713
– This applies to Insulating Glass units (double glazed units)
and is soon to be replaced by the new European standard. EN1279
BS-7413
– This is the standard for PVC-U Profiles (the framing material
for PVC-U windows).
It’s
worth noting that both BS-7413 and BS-5713
are required within BS-7412, so if you are purchasing
Kitemarked windows you should not need to specify these standards
separately.
What
to look for
Kitemark certified windows display
the Kitemark and the Standard Number in close proximity. This is usually
on the inside of the frame (ie not visible when the window is closed).
You may also see the Kitemark used
in advertising. Where the company is not Licensee but purchases from
a Licensee they must use the Licence number (this is prefixed with
‘KM’) in addition to the standard number as shown left.
The Licence number is unique to the Licence holder and allows the
window to be traced to the manufacturer.
