VEKA Softline profiles make 5-chamber system (5 chambers in the frame profile and 5 chambers in the sash profile) with an installation depth (i.e. frame width) of 70 mm, which guarantees efficient heat protection. When using a glazing unit with a hot frame featuring Ug=1.0, heat transfer coefficient Uw=1.1 W/m2K for the entire window is obtained.
With these profiles it is possible to use 6 to 49 mm thick glazing.
External wall thickness of the profile is 3 mm (with a tolerance of 0.2 mm), which is a parameter meeting the highest RAL standards – “Class A” (PN-EN 12608).
The system of two external gaskets ensures excellent tightness as well as acoustic and thermal insulation. Use of gaskets with a directional surface including a 15-degree slope enables excellent drainage of water and dirt..
