Featured Project

Touchstone Glazing was proud to contribute to the restoration of the Grade I listed Halifax Piece Hall, one of the most significant Georgian buildings in the UK. Working with LDN Architects, we were tasked with improving the thermal performance of the historic mullion and tracery windows, including a striking 5-metre rose window made up of 81 individual shapes.

Using our patented Insulead® system, each opening was individually templated to create bespoke double-glazed units that preserved the original appearance while significantly improving efficiency. The project was approved by Historic England and helped the restored Piece Hall become a thriving cultural centre once again.
