Veka Softline 76 represents an evolutionary development of classic window systems, offering improved thermal properties without a significant cost increase. This is a system with 76 mm installation depth, occupying the "golden mean" niche between basic 70 mm profiles and premium 82 mm systems. With a 3 mm outer wall thickness (Class "A" according to DIN EN 12608), the profile guarantees exceptional shape stability and weld seam durability.
The increased installation width allows for wider and warmer glass units up to 48 mm thick, significantly improving sound insulation and home heat retention. The narrow visible profile part (mullions) ensures maximum daylight penetration, making the room visually more spacious. This is the ideal choice for glazing modern cottages and apartments with high energy efficiency requirements.

FAQs
Standard glass unit seating depth is 18-20 mm. Increasing it to 25 mm allows completely hiding the spacer bar behind the profile plastic. This eliminates the "cold bridge" at the edges and dramatically reduces the risk of condensation in freezing weather.
Thanks to the additional 6 mm width and the ability to install 48 mm glass units, the overall thermal resistance of the finished window increases by approximately 10-15%, which is noticeable when heating a private home.
Yes, Softline 76 is the main platform for the unique velvety Spectral coating. The profile is laminated on a colored core (gray, graphite, umber) so that when opening the window, no white gaps are visible.
With reinforced hinges and bonded glass unit, the sash can weigh up to 100-120 kg, allowing panoramic opening elements up to 2.4 meters in height.
Yes, this system has its own reinforcement articles precisely matching the chamber geometry. Gaps between plastic and metal are minimal, providing maximum structural rigidity.
Absolutely. Moreover, thanks to the thick Class "A" walls, hardware screws hold more securely, making it harder to force open the sashes with a crowbar.
