WINTECH composite windows fivechamber profile systems with mounting width 70 — 79 mm

Profile material - composite, Outer width of the frame - 70 mm, number of chambers in the frame / sash - 5/4

Penwood - profile system made of composite material: PVC and wood flour. According to the calculations of engineers, profiles do not require the use of the reinforced type, thereby increasing the thermal insulation characteristics. The heat transfer coefficient of the window is 1.1 W / m ^{2 …}
