Windows

Windows are especially important in energy efficient house, firstly they can act as a great collector of free energy by allowing solar gain into the property, however this needs to be tempered by the fact that they can bring in too much light and heat and also that they lose heat during the night and cold weather. The quality of the glazing, spacers, construction and installation is therefore very important. For that reason we have relations with the following:
