Why Velux Modular Skylights?
Sub-construction
An accurate sub-construction precedes a trouble-free installation
To achieve a trouble-free installation process the sub-construction needs to accommodate the unique module installation system. VELUX Modular Skylights require an accurate fixed dimensioned substructure.
Likewise the strength of the subconstruction needs to be calculated from project to project, based on the building design and application size. Hence the sub-construction is not part of the prefabricated modular system.
