Thermal Simulator In-House

In-house, specialist advice on thermal efficiency is now available.

We continue to be proactive in researching thermal ratings for our windows alongside the British Fenestration Ratings Council.

Having a thermal simulator in house strengthens our focus on the thermal aspects of window development.

We were the first in Britain to achieve an “A rated” timber window and have continued to design windows with the best performance without the need for expensive glazing units and unattractive profiles. We now have the largest range of accredited timber windows in the industry.
