The VEKA SOFTLINE 82 MD system is a particularly high-performance system with a centre seal. The innovative multi-chamber geometry of SOFTLINE 82 MD ensures excellent thermal insulation with values of up to Uw = 0.74 W/(m²K) when using highly insulating triple glazing withUg = 0.5 W/(m²K)
In a thermally optimized version with thermally separated steel reinforcements, SOFTLINE 82 MD also easily meets the most stringent energy efficiency requirements – from low-energy houses to passive houses.
VEKA window and door profiles have outer wall thicknesses of 3.0 mm on the visible surfaces and 2.7 mm in the rebate or connection area (tolerance 0.2 mm in each case). According to DIN EN 12608, these are therefore profile systems of the highest class. What’s more: In Germany, VEKA is even the only manufacturer that exclusively produces Class A plastic profile systems. In order to reliably achieve these particularly high wall thicknesses, VEKA uses around 14% more material in profile production than would be sufficient for lower class B profiles.
The fact that the higher wall thickness of class A profiles actually results in higher performance is proven by extensive measurements. The series of tests in material testing at VEKA showed that windows made of class A profiles have 15-20 % higher corner strength compared to those made of class B profiles. Dimensional stability is also greater, as shown by 10-12% less deflection under load. Also measured was the force required to pull bolts out of the profile: this is up to 20% greater for Class A profiles than for less strong-walled Class B profiles.

SOFTLINE 82 MD opens up additional design options, as the system is available in a recessed as well as in a semi flush area version. Thus, the windows can be perfectly adapted to any architectural style
With SOFTLINE 82 MD, different variants of glass bonding can be realized. Special sash profiles for glass edge bonding enable maximum stability and safety with the highest processing efficiency
For the highest energy requirements, various thermally separated sash and frame reinforcements are available for the SOFTLINE 82 system. They enable Uf values of up to 0,94 W/(m²K)
Aluminium cover profiles open up additional possibilities for the design of windows and doors. The panels can be anodized or powder-coated in all RAL colours. Placed on the outside of the frame and sash profile, they combine the high-quality metal look of aluminium with the technical advantages of PVC-U.
