A Grade II Listed building in West London became one of a growing number of double glazed listed buildings in London and the Home Counties when we carefully restored and replaced the windows and doors on the historic property.
The White House, which over-looks the River Thames at Isleworth, was remodelled in 1832 for Sir William Cooper, Chaplain to George III.
Our client, a developer of high end residential apartments and homes, wanted to improve the noise insulation of the windows, being under Heathrow Airport’s flight path, while maintaining the original architectural integrity of the property.
Because some of the timber windows and doors needed to be replaced, while others could be saved and restored, the project required a complex combination of our specialist services, including refurbishment, part-replacement and full replacement of the sash windows and bow-fronted french doors.
By using a range of specialist single and double glazing types, we worked with our client and planning officials in Hounslow to ensure the replaced and refurbished windows and doors met all thermal and acoustic requirements, without changing the unique design and character of the property.
The restoration work on the windows that could be saved included draught proofing, de-glazing and re-glazing with single glazed, restoration laminated glass. Restoration glass has the authentic uneven surface of the original heritage (crown) glass, and laminated glass not only gives extra security, it also has improved heat and sound insulation.
For the windows that couldn’t be saved, if the original frame was in good enough condition, we replaced the moving sashes only. These replacement windows were hand-puttied and hand painted, and featured exact-match mouldings, slender true glazing bars and our slimline double glazing Timbalite, that looks just like single glazing, to improve thermal and acoustic performance while retaining the historic look of the property down to the finest detail.
As specialists in timber windows and doors for period, conservation and listed properties, at Timbawood we have successfully fitted single glazing and slimline double glazing on listed buildings and conservation properties in over 30 planning authorities throughout London and the South East, including Westminster, Kensington and Chelsea, Islington and Greenwich*.
