- Thermal insulation of the profiles Uf = 1.0 W / m²K
- The standard variant with an additional central gasket is a system of three gaskets (external, middle and internal) that perfectly insulates noise, cold, moisture and drafts.
- The thickness of the external walls of the profile is 3 mm (with a tolerance of 0.2 mm), which is a parameter that meets the highest RAL standards - "Class A *" (PN-EN 12608)
