Built for the demands of social housing.
Scottish local authorities and housing associations are facing a challenging window of opportunity. The Scottish Government’s EPC-B standard for all social housing by 2032 requires a sustained and well-managed investment programme. Inefficient windows and doors are consistently among the biggest sources of heat loss in residential properties.

Sustainability built in, not bolted on
From the windows and doors we make to what happens to materials when we take old ones away.
Our windows and doors are designed to reduce emissions through increased thermal efficiency, with u-values reaching as low as 1.2 in double glazing. Our commitment to sustainability goes beyond the product. We have an ongoing multi-million-pound investment in our Fife manufacturing facility, reducing waste and improving energy efficiency across our production processes.
