Window-door system with thermal insulation

This is three-chamber system for the construction of external doors, windows and all sorts of shop windows. The thermal insert applied in profiles, 24 mm wide, is made of polyamide enriched with multi-directional oriented fibreglass, substantially increasing mechanical durability of joints which are most exposed to multi-axis stresses. Thermal insert was additionally equipped with Coex sealing wire, which creates a reliable vapour barrier and an excellent sealing layer during the curing of powder-painted profiles. IMPERIAL door profiles have heat transfer coefficient UR=2,2÷2,3 W/m2K, classifying them in the materials group 2.1 as per DIN 4108. Due to the parameters:  profile width 65 mm (window and door outer frames, pillars and door wing),  window sash width 74 mm and wall thickness 1.7 – 2.0 mm a stiff and static profile was achieved. It allows constructing doors at maximum dimensions of the door leaf: width 1300 with a maximum height of 2200 mm, width 1200 with a maximum height of 2400 mm.  Panel fixing system from 4 to 51 mm (glazing from the outside), branded hardware and wide selection of thresholds makes it a modern and universal system. The advantage of IMPERIAL  windows is the possibility of proper selection of window dimensions (several types of window frames and sashes) and the selection of the sash depending on the hardware, as there are sashes designed for typical aluminium hardware, in accordance with EURO standard, and hardware for PCV windows.
