5Stars PVC Heat-Insulation Windows

Number of chambers and mount depth for 5Stars PVC Profile

• 5 chambers in the fixed window frame
• 5 chambers in the window frame (moveable)
• 70 mm profile width (mount depth)
• outer wall thickness of PVC profiles: ≥ 2.8 mm

Both the number of chambers of the PVC profile and the mount depth and thickness of the outer wall are particularly important elements for providing heat insulation and noise insulation, as well as the high durability features of QFORT heat-insulation windows.

• 2 glass support gaskets
