White PVC frame and sash components with extruded gaskets. White framed insect screen included as standard. VCM needs a custom flashing made by roofer, see preparation guide overleaf.
On skylights, flashings and glazing
The brilliantly simple fixed, FCM skylight incorporates the VELUX High Performance double glazing unit and an all metal exterior frame. The smooth exterior gives not only a lower profile on the roof, but also provides a “cool” daylighting solution by effectively blocking heat build up and UV rays.
Laminated glass (standard with VCS) must be used
for skylights installed 3m or more above floor level.
* VELUX recommends VCM is installed with a slight pitch (e.g. 3°-5°) to help reduce condensation build-up and water ponding on the glass.
** Winder handle and extension rods to be purchased separately. Details overleaf.
The VELUX FCM flat roof skylight requires custom-made flashing (not supplied). VELUX can assist with technical advice and drawings for this type of flashing.
FCM SKYLIGHTS ARE IDEAL REPLACEMENTS FOR ACRYLIC DOMES.^
11 sizes are available to replace common acrylicdome sizes.
† FCM Skylights can be positioned in portrait, landscape or even ‘diamond-shape’ orientation, except for FCM 2270 which is recommended only for portrait applications.
^ Custom-made collar adaptor (not supplied) required to fit.
‡ Weight does not include flashing.
