ENERGY-EFFICIENT WINDOWS Uw = 0,9 W/m2K
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 68 mm systems, the depth of both the wooden frame and the sash is 88 mm and additionally there is an aluminium cladding fitted to outside of the window. Usually equipped with 2 or 3 gaskets and triple glazing with either Argon or Krypton to achieve the U value Ug=0,5 W/m2K.

PASSIVE WINDOWS Uw = 0,77 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. Drewexim also offers a special version of energy-efficient window with additional insulation inside the frame and the sash. It is a construction material, also biologically harmless, formed from polyurethane foam's hard particles, joined at high pressure by means of a formaldehyde free binding agent. It is common in building construction especially where efficient thermal insulators are required. This material is a better insulator than wood, morphologically stable under extremely wide temperature variations (from -50°C to +100°C for prolonged periods of time). Thanks to using this material and triple glazing the window meets all the highest energy-efficiency and quality norms. The total U value for the whole window is Uw=0,77 W/m2K certified by the Institute for Window Techniques in Rosenheim.
Passive windows are a perfect solution also for your environment. The best characteristic of such window is money saving, perfect insulation, durability and healthy microclimate in the building.
