Veka Softline 70 is a premium system that sets quality standards in the window industry. Unlike many competitors, this is a genuine Class "A" profile according to DIN EN 12608 standard. This means the outer wall thickness is 3 mm (±0.2 mm). This strength margin ensures exceptional window geometry, rigid corner joints, and long-lasting hardware that is securely fixed in the plastic.
The five-chamber design with a 70 mm installation depth creates a powerful barrier against cold and noise. Thanks to the ability to install glazing units up to 42 mm thick and the use of high-quality seals, windows made from Veka Softline profile make your home truly energy-efficient. This is the choice for those who won't compromise on reliability and are looking for a "set it and forget it" solution for the next 50 years.

FAQs
The 3 mm wall provides 15-20% stronger corner weld seams compared to economy Class "B". This guarantees that the windows won't deform, hinges won't tear out of the plastic, and the sash geometry will remain perfect for decades.
The Veka frame uses a square steel tube (closed contour). It has 4 stiffening ribs, while U-shaped has only 2. This is critically important for resisting wind loads and the weight of heavy sashes, preventing frame "twisting" during installation.
We recommend a double-chamber glass unit 40-42 mm thick with two low-E glasses and a warm spacer bar. This will maximize the thermal performance of the Softline 70 profile.
Yes. Unlike systems with co-extruded (fused) seals, the Veka Softline seal rolls into a groove. If needed, it can be easily removed and replaced with a new one without replacing the entire window.
Perfectly. Thanks to the thick outer wall and powerful reinforcement, the profile withstands thermal expansion of dark lamination in the sun without warping, which often happens with thinner profiles.
Euroline is a 3-chamber system with 58 mm width, more suitable for balconies or summer houses. Softline 70 is a full-fledged 5-chamber system with 70 mm width, designed for thermal glazing of apartments and cottages.
