Triple glazed
Passive House windows, made in Wales.

Triple glazingCaring for the environment
Responsibly sourced timber. Nothing wasted.
Our timber is traceable back to the source forest. Offcuts are recycled into briquettes that heat our workshop and are sold for home heating, and we use water based paints and finishes wherever possible.
