Multi-chamber Perfectline profiles (70 AD) provide very good thermal insulation.
Perfectline profiles can accommodate double glazing units with a thickness of 6 to 42 mm. With the appropriate glazing package and correct installation, windows with Perfectline profiles meet the requirements of sound insulation class 6 (noise attenuation up to 50 dB). They are therefore ideal for buildings located, for example, near expressways.
The depth of the glazing packet assembly in the profiles is 21 mm, thanks to which the windows are less prone to dewing. They are also more difficult to force.
