» » IT IS NOW SIX YEARS SINCE
compliance with the Construction
Products Regulations (CPR) became a legal
requirement in the UK. The CPR (which
replaced the Construction Products Directive)
was implemented in the UK, on 1st July
2013 and requires all construction products
placed on the market, which fall within the
scope of a harmonised European Standard
(hEN), to have a Declaration of Performance
(DoP) produced by the manufacturer and
be CE Marked in accordance with the
requirements of the CPR.
In terms of Insulating Glass Units
(IGUs), the relevant hEN (Harmonised
European Norm) is EN 1279-5:2018 –
Product Standard, this standard details the
requirements to comply with the CPR.
In turn, EN 1279-5:2018 requires IGU
manufacturers to have test evidence to show
compliance with:
• EN 1279-2:2018 – Long term test
method and requirements for moisture
penetration
• EN 1279 3:2018 – Long term test
method and requirements for gas
leakage rate and for gas concentration
tolerances
• EN 1279-4:2018 – Methods of test
for the physical attributes of edge seal
components and inserts; and a system
description in accordance with EN
1279-1:2018 – Generalities, system
description, rules for substitution,
tolerances and visual quality.
IGU manufacturers must also operate a
Factory Production Control in compliance
with EN 1279-6:2018 – Factory production
control and periodic tests.
The CPR does allow manufacturers
to refrain from drawing up a DoP and

CE Marking products under certain
circumstances, these are known as derogations
and are detailed in Article 5 of the CPR.
There are three conditions under which a
derogation is allowed. These are detailed in
the GGF publication, ‘Insulating Glass Units
(IGUs) – Conforming to the Construction
Products Regulation (CPR)’, which can be
downloaded from the Members Area on the
GGF website.
This publication also details the GGFs
interpretation on the application of these
derogations in relation to IGUs being placed
on the market. The GGFs position is that the
derogations do not apply to the manufacture
of any IGUs and Best Practice advice to
Members, is to ensure they always have their
products tested to the appropriate parts of
EN 1279 series, have a system description
specific to all specifications of IGUs they
manufacture, have an appropriate Factory
Production Control in accordance with EN
1279-6:2018 and create a DoP and CE Mark
for their product ranges. This is also clarified
in documents on CPR 07/07/1 from the
European Commission.
By following the GGFs guidance, IGU
manufacturers will be able to demonstrate
compliance with the product standard, EN
1279-5:2018 and comply with the legal
requirements of the Construction Products
Regulations.
