Building Envelope
Crittall reinforces Mayfair chic
One of Mayfair’s most prestigious apartment blocks has undergone a transformative refurbishment with a major contribution
from Crittall Windows.
Chesterfield House, close to Park Lane, was built in the late 1930s
on the site of a Georgian mansion of the same name.
The nine-storey mansarded block comprises 105 flats providing residents
with high specification accommodation and a full porterage service.
The refurbishment works called for the removal of all existing original steel
windows and their timber subframes which were then replaced with new
timber subframes clad externally with special aluminium extrusions to
ensure the external surfaces were maintenance free.
New Crittall Homelight Plus double-glazed self-cleaning windows were
then installed into the subframes.
“The original windows were Crittall and Westminster Council planners
insisted that there should be a like-for-like replacement,” says Annika Blixt,
General Manager of Chesterfield House Management who considered
various alternative suppliers but concluded that Crittall’s proposals best
replicated the general appearance of the building while improving the
insulation value of the fenestration.

Marley Eternit launches new Roof System Specification Guide
Marley Eternit is helping to make roof system specification easier with the launch of
a new version of its popular roofing guide.
The 2017 Roof Systems Specification Guide now includes all of the information architects
need to design and specify a complete pitched roof system, ensuring compliance with BS
5534 and reducing the risk of product substitution.
Marley Eternit’s new guide covers more roofing elements than ever before, from battens and
underlay to clay and concrete tiles, fibre cement slates, profiled sheeting, shingles and shakes,
right through to ventilation and fixings. It covers all aspects of roofing design and practice,
including building regulations and standards, as well as the management of condensation,
thermal insulation and weather resistance.
Alex Gill from Marley Eternit, explains: “Just like the rest of the construction industry, we know
that architects and other specifiers are increasingly stretched. With more projects, less time,
new innovations and changing regulations, they can’t be experts on all products. That’s
where support from manufacturers is vital and resources like our new Roof System
Specification Guide can be invaluable. We’re sure that this new, more comprehensive, guide
will prove even more popular than previous editions.
“Recent figures from the NBS Specification survey show that 78 per cent of respondents think product substitution is still an issue in the industry, so
there is a clear role for manufacturers to support specifiers in developing robust specifications that protect design intent. Using a complete tested
roof system from Marley Eternit can help specifiers take greater control of the supply chain, with less risk of product substitution further down the
line. It also delivers clear levels of accountability and integration, giving greater protection to specifiers by helping to reduce risk to their design
liability.”
Marley Eternit offers the most comprehensive pitched roof system on the market, with more elements guaranteed to work together than any other
manufacturer and a fifteen year system guarantee.
