Specifiers Guide

The Steel Window Association (SWA) represents UK steel window manufacturers, ranging in size from the smallest, craft-based companies which specialise in replacement and repair work through to large, multi-site companies that manufacture and install windows in all types of buildings.

SWA works with English Heritage to promote the important conservation message that metal windows can be cost effectively renovated or replaced by skilled tradesmen.

The Specifier’s Guide to Steel Windows is published by the SWA to assist architects, contractors and other members of the building supply chain to select the right steel windows for their projects in both the private and public sectors.

Whilst this guide focuses primarily on new steel windows, it is possible to renovate and upgrade existing frames – even those dating back to the start of the 20th century. This can be particularly desirable in listed buildings and buildings in conservation areas where the existing windows need to be preserved but there is a desire for enhanced acoustics, thermal insulation, draughtproofing and security, which do not compromise the aesthetics of the building.
