Drewexim offers special windows with improved thermal insulation which can help you reduce the heat loss in your building and reduce the energy consumption which results in lower costs of energy. These windows are slightly thicker than standard 68mm systems, the depth of both the frame and the sash is 88mm. Usually equipped with 2 or 3 gaskets and triple glazing with either Argon or Krypton to achieve Ug=0,5 W/m²K.
Standard energy-efficient window achieves U value approx. Uw=0,9 W/m²K. The biggest advantage of this system is very good thermal insulation with relatively low price.
