By using the energy calculator developed by the Glass and Glazing Federation (GGF) – an independent authority in the replacement windows industry – we are able to calculate the potential annual savings for a property if the windows were upgraded from your existing windows to A-rated Planitherm casement windows.
The examples below give some typical examples of potential savings in homes as a result of replacing windows with Planitherm A-rated windows. The figures are based on the GGF's typical house*.
Replacing a typical 3 bedroom house, that has aluminium framed single glazed windows and is heated by gas, with JC Windows A-Rated casement windows.
Replacing a typical 3 bedroom house, that has timber framed single glazed windows and is heated by gas, with JC Windows A-Rated casement windows.
