Touchstone has built an outstanding reputation within the Conservation world for its passion for developing and manufacturing innovative products which offer unique solutions for thermally efficient windows, doors and roof-lights. Our glazing solutions not only protect the fabric of historic and listed buildings but look nearly indistinguishable from the original whilst offering the best in thermal efficiency.

With over 25 years making and repairing stained glass and leaded lights, Touchstone realised there was a need to develop new technologies which offered thermally efficient alternatives. With this in mind we developed Insulead®, a frameless, fully drained and thermally broken glazing solution. Insulead® allows historic and listed buildings to be double glazed without damaging the fabric of the building, looks virtually identical to the original and is made using traditional techniques and materials. Our Steelyte® opening casements are stainless steel, fully weather-stripped, thermally broken and have achieved a BFRC ‘A’ rating for thermal efficiency.
