Passivhaus standard windows and doors
To complement the air-tight, well insulated structure of your home it is vital that windows and doors are manufactured and installed to a similar high specification. They must be super-insulated, draught proof products and need to be fitted in such a way that no air escapes around the edges of the frame, which is a common problem when lesser quality windows and doors are poorly installed.
Typically, these windows are clad in aluminium to the external face to minimise the need for maintenance, triple glazed and draught free, with special attention paid to minimalise and eliminate thermal bridging through the frames.
The windows and doors we are currently recommending are Internorm/Ecohaus, Rationel and Green Building Store triple glazed windows.
