Saving energy, cutting costs

Saving energy with Wiltshire GlassSave hundreds of pounds and lower your carbon footprint by replacing your old single glazed timber or metal windows with our ENERGY EFFICIENT double glazed or triple glazed windows and new doors.

There are two methods now in use for measuring the Energy Efficiency of double and triple glazed windows and also doors, so they comply with Approved Document Part L (2010) of Building Regulations for England and Wales.

U Value

The minimum performance level required for double and triple glazed windows and also doors is a ‘u value’ standard of 1.6W/m2K for windows and 1.8W/m2K for doors. This is easily achieved with the Rehau and Kommerling Window Profiles by glazing with double glazed units comprising of SOFT COAT LOW EMMISSIVITY GLASS WITH ARGON GAS FILLED CAVITY.
