Main doors, French doors and windows are responsible for over 30% of heat loss. In particular, the heat losses due to the transparent surfaces account for 25%. Clearly then, it's important to have best-performing fixtures with a low thermal transmittance (the U-value), in order to minimize heat losses.
In the case of energy redevelopment projects, the achievement of the desired results is due not only to best-performing fixtures, but you also need a proper installation. Quemme's products ensure high energy savings, thanks to its high performance of thermal insulation. The insulating properties of our products guarantee a reduction of energy consumption on heating and cooling of your home.
