The three-chamber profile system was designed to meet the highest thermal insulation requirements. It features a Euro-standard hardware groove, suitable for both windows and balcony doors made of PVC or wooden profiles. The system is ideal for energy-efficient and passive buildings, achieving a Uw heat transfer coefficient of less than 0.8 W/(m²K). High thermal insulation is ensured by 62 mm wide multi-chamber thermal breaks and a two-component central seal. The design allows for the construction of large-sized elements, as well as flush-fitting the window sashes with the frame, creating a single surface on the exterior. The system offers a variety of corner connections and the use of 22 mm and 28 mm high glazing beads, allowing for flexible solutions tailored to individual design needs.
