Modern WindowsModern windows Throughout the history of the windowThey were considered as a kind of gaps in the enclosing structures. The translucent filling of the old-style window frames accounts for 50-80% of the heat losses in the building. Gaps in the contiguity of single glass to the hinge, a loose porch, an unsealed seal of the frame joint with the wall - loopholes for drafts, dust and street noise. Sealing, putty only partially solve the problem, while worsening the appearance of the frame. KBE, system "Expert", version "Extra +" - four-, five-chamber profile 127 mm wide. Two sealing circuits. Solving the problem of cold bridges and falling out along the perimeter of the window block Montblanc city 120 - five-chamber wide profile120 mm. Prevents the occurrence of cold bridges along the perimeter of the window. The large installation width provides the window with increased stability. Modern windows are complex systems. Their main components are hermetic energy-saving double-glazed windows and frame structures. The latter are made of a heat-efficient system profile that combines the frame and the curved components. Profile systems are made of PVC, "warm" aluminum and glued beams. The tightness of the fitting of the sash to the frame and double-glazed windows to the frame profile provides the contours of the seal of artificial rubber. When installing the window in the opening, the assembly seam (the space between the frame and the wall) is filled with a foam insulation and protected with steam and waterproofing materials. Thus, the system is completely impermeable. A convenient, reliable and multifunctional operation of the window provides high-tech fittings. The system also includes accessories and accessories: reflux, window sill, slope finishing, mosquito nets, etc. Thermotech c king (Thermotech) is a five-chamber profile with a width of 120 mm with a composite reinforcing profile inside the chamber. Increased frost resistance. Two sealing circuits. Wall thickness 3 mm Proplex-Lux 127 - combined system: five-chamber wide frame (127 mm) profile and three-chamber curved profile. Supports positive slope temperature and prevents condensation
