Windows

To the rear of the property all windows and doors have been replaced with high performance low e argon filled IG units. Windows to the front (5 number) are, however, box sash windows which form a significant feature of both the house and the conservation area in which it is situated. These windows are to be fitted with very high performance secondary double glazing, which will mean that the most difficult windows become triple glazed.

Roofs

The Main house roof is conventional and high levels (300mm) of insulation has been installed.
More problematic is a small room to the rear of the property. This part of the building predates the main house and is believed to be a part of the original cottage on the site. Here 50mm Kingspan insulation has been installed between rafters, with cross battens with a multi foil insulation material stapled in place. The foil insulation was carefully taped at joins and edges, before adding further battens to take a plasterboard finish. Multi foils are the subject to much debate, as to thier true insulation value, but combined with at least some conventional insulation a reasonable level of insulation close to current minimum new build levels has been achieved. Long term the roof covering will be replaced with additional extenal insulation board.
