All elements are joined together without visible screw joints.
The masking strips are cut in the corners at the right angle.
The elements of the internal window cavity are optimally matched to all other VELUX products, ensuring that they are perfectly combined when installing the window
attics

Cover strips are made of double-layered PVC.
The main/base layer is made of PVC reinforced with organic fibres, while the outer layer is 0.5 mm thick PVC in white.
