Sash Window Preservation can offer double glazing for your existing sash windows without the costly expense and disruption of replacing the whole sash box and frames. Using a slimlite double glazed unit, we are able to fit this into the existing frame which means the original look of the window is retained. By doing so, the homeowner gains all the thermal and sound benefits without compromising the charm, character or value of their property.

 

“It is not often that I get blown away by a building product, but I find this absolutely extraordinary, it looks like a single pane of glass.”

 

— Kevin McCLoud (Grand Designs) 2009

 

Replacing the entire sash window can often lead to new windows that are not entirely in keeping with the period property. At Sash Window Preservation we believe the windows play a huge part in the appearance and character of the property.  By modifying the existing windows to accommodate a slim double glazed unit, the aesthetics of the property is retained.

 

With Sash Window Preservation you can be assured that the work will be completed to a very high standard. We are based in Norwich, working across the East Counties and London. We are CERTASS qualified and a CHAS accredited contractor, so a company you can completely rely upon.
