Manufacturers of frameless double glazed units suitable for heritage buildings

With over 30 years’ experience in the traditional leaded light industry Touchstone's patented Insulead^® glazing system and Steelyte^® opening casements were designed specifically to overcome the problem of double glazing windows in a heritage building situation where no provision is made for glazing other than the original.

Our patented, frameless, high performance double glazed units fit directly into stone which along with our stainless steel opening casements offer a glazing solution for both heritage properties as well as new developments

No modification to the existing fabric of the building is required as the Insulead^® glazing fits where the original was located, and is made by our skilled craftsmen using only traditional materials. Our Steelyte^® opening casements incorporate a PVC edging in order to protect the stonework. Made of stainless steel throughout they have been designed to have the delicate look and have the benefits of a traditional metal window whilst offering the absolute best of insulating properties.
