Drewexim also offers a special version of energy-efficient lift & slide doors 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 balcony door meets all the highest energy-efficiency and quality norms. The total U value for the whole door is Ug=0,77 W/m2K certified by the Institute for Window Techniques in Rosenheim. Passive lift&slide doors are a perfect solution also for your environment.
