Advantages of the SOFTLINE 70 AD profile system
Good thermal insulation
Uw = 0.83 W/(m²K) with Uf = 1.3 W/(m²K), Ug = 0.5 W/(m²K), ψg = 0.03 W/(mK) thanks to which windows with these profiles reduce heating costs.
High-quality seals
The stop seal system with two seals reliably protects against cold, drafts and moisture. Seals in a choice of gray or black.
VEKA’s highest quality
VEKA offers only profiles of the highest class A (according to PN-EN 12608). The thickness of the external walls of the profiles is 3 mm (with a tolerance of 0.2 mm).
Slightly rounded contours
give the SOFTLINE AD system a classic look
