As one of the leading profiles manufacturers in the world, Veka AG exclusively produces the highest quality frame profiles, Grade A, according to the DIN EN 12608. Profiles of grade A are the ideal base for quality frames. They are sturdier and their angular bonding strength is up to 20% higher than Grade B. In addition, Grade A profiles are more difficult to deform compared to Grade B profiles, as their bending and distortion are 12% lower than Grade B. Regarding the tensile strength of screws on the PVC, Grade A profiles provide the mechanisms with safer support as approximately 20% strength is required.
They provide greater protection against break-ins, high thermal and sound insulation values, and remain fully functional even after many years of use.
Under the excellent material properties and the guaranteed external wall thickness of 3.0 mm (0.2 mm tolerance), Veka profile systems allow the production of extremely high performance windows and doors that have been reliable for decades.
Grade B profiles have a lower wall thickness. In their construction 14% less material is used. This missing volume leads to clear measurable differences in stress tests.
