The VELUX ZWC 0000T window profile set is for use with an on-site flashing kit.
The VELUX ZWC 0000T is the option available if you want to install a VELUX window on a non-standard roof, such as Zinc, Lead, Single ply membrane and GRP Fireglass.
The set consists of a covering for the head of the window that hooks over the top hood section and overlaps the roofing material as it is dressed up the window frame. It works with the side and bottom frame covers supplied with the window.
The special head flashing is manufactured from aluminium, in a matching colour to the profiles of the window.
