For customers that want the benefits of double glazing but don’t want to compromise of the look and slim proportions of a traditional sash window.

At The Heritage & Restoration Group , we specialise in converting single paned wooden windows into slim double glazed sash windows, using our 12mm sash window double glazing units. Our units are ultra slim meaning that from a distance they still appear to be single glazed sash windows and therefore in keeping with your property. Once beaded or puttied in our units will still appear to be single glazed glass thus keeping the traditional look but with all the benefits of modern double glazing. Our units achieve a 1.9UV couple this with draught proofing and the benefits are instantly noticeable. Our references speak for themselves with customers that have old draughty, rotten sash windows that did not open to rot and draught free sash windows fitted with slim double glazing fully draught proofed and restored to their original glory but with the benefits of modern day improvements.

Should our customers wish to have slim sash window double glazing then we offer two ways to achieve this. We will advise our customers of the best options for their particular project on our site survey. Firstly one is to manufacture new sashes to match your existing ones with the same slim profiles, glazing bars and look, fitted with our slim double glazing installed in them. We would then replace your old sashes for the new ones. Our remaining option would be to modify your existing sashes and install directly into them. This is achieved by routing back your existing sashes to allow enough room for our sash window double glazing units to be fitted.

Please take time to view our references a see what our customers think about us and the benefits they have gain from our service. For new customers wishing to see a completed project or speak with a previous customer please don’t hesitate to get in touch.
