1960S CHESHIRE BUILDING TRANSFORMED
INTO STYLISH MODERN HOUSING
Over 1,000 Profile 22 Optima Chamfered Windows
have been used in the transformation of a disused
1960s office building into 184 studio, one and
two bed ultra-high quality apartments aimed at
young homeowners in Cheadle Hulme, Cheshire.
Sim Chem House, a six
storey office block had been
built in the 1960s but had
been empty for many years
and fallen into disrepair. It
was purchased by develop-
ers Inspired Homes for re-
development into housing.
With the focus on quality,
throughout, the choice
of window was critical.
The specification was for
1,050 PVC-U foil wrapped
windows in a specific RAL
colour on the exterior and
white on the interior. The
windows needed acoustic
treatments to address noise
from a busy town centre
location and incorporate
louvres for mechanical
extraction.
Main contractor headof-
fice3 awarded the win-
dow contract to Profile 22
Approved Window Con-
tractor Kingfisher Windows
because it was able to meet
the exacting specification
requirements.
Kingfisher tendered for
the work with Profile 22
Optima Chamfered Win-
dows, a popular commercial
system thanks to its intel-
ligent design, impressive
performance and attractive
good looks.
The Optima system deliv-
ers a 1.2 W/ m2K U-value
as standard, with U-val-
ues as low as 0.8 W/m2K
possible. It achieves PAS24
2016 Enhanced Security and
there are Secured by Design
options when security is a
concern.
To meet the specifica-
tion requirements on this
particular project, Kingfisher
glazed the 1,050 windows
with a soft coat low emis-
sivity glass, a warm edge
spacer and argon gas to
optimise thermal efficiency.
Louvres were also glazed
within the window system
for mechanical extraction.
Anthracite 7016 textured foil
was used for the external
elevations with white on
internal elevations.
The redevelopment was
completed in March 2019
and has created much-need-
ed high quality affordable
housing for young profes-
sionals in the area.

GGF ISSUES STATEMENT ON CPR AND INSULATING GLASS UNITS
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 rel-
evant hEN (Harmonised Eu-
ropean 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 compli-
ance with:
• EN 1279-2:2018 – Long
term test method and
requirements for mois-
ture 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 compo-
nents and inserts; and
a system description
in accordance with EN
1279-1:2018 – Generali-
ties, system description,
rules for substitution,
tolerances and visual
quality.
IGU manufacturers must
also operate a Factory Pro-
duction Control in compli-
ance 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.
There are three conditions
under which a derogation is
allowed, as detailed in the
GGF publication, ‘Insulating
Glass Units (IGUs) – Con-
forming to the Construction
Products Regulation (CPR)’,
which can be downloaded
from the Members Area on
the GGF website.
This publication also
details the GGF’s interpre-
tation on the application
of these derogations in
relation to IGUs being
placed on the market. The
GGF’s 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 appro-
priate 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 Euro-
pean Commission.
