** FCM 2270 not recommended for “landscape” orientation.
* VELUX recommends FCM is installed with a minimum pitch of 3°-5° to prevent condensation build-up and water pooling on the glass.
† U-value (W/m2K) and SHGC data based on AFRC simulations for 2004 glazing, (FCM complete skylight: size 1275mm x 1275mm).
^ Bushfire testing applicable in roof pitch 0°-60°. Skylights only. Custom-made flashing required.
‡Preparation guide for custom made flashing
FCM must be installed with insulation and Gyprock, as shown (typical installation), to achieve 3.3 U-value rating.
