Installation process

Attachment to the roof principles

VELUX Glazing Panels are, regardless of solution type, installed using an installation profile in the top connecting the panels together.

The individual panel and main parts of the accessories are prefabricated off-site, making the installation easier on-site. Due to the bespoke nature of the panels, the installation must be carried out by a trained installer or with support from a VELUX technician.

The panels are attached to the roof in the top and the bottom of the panels. In the bottom, the panel is attached using a pre-mounted mounting bracket which must be screwed into the sub-construction. For venting panels, the mounting bracket must not be screwed into the sub-construction. At the top, the panel is installed using an installation profile which must be fastened to the sub-construction or wall in wall-mounted solutions. At the ends, the panel is finished against a side gable which is screwed into the sub-construction or a wall. The installation is completed with gaskets and flashings, ensuring a weathertight solution.
