Suitable for flat/low-pitch roofs, our VCM manual skylight is the healthy choice for visually expanding interiors with daylight, fresh air and sky views. Great for bathrooms, kitchens, laundries and any rooms needing a daylight and fresh air transformation.
  • Toughened, argon fill, double glazing with Low-E3 coating

  • Includes removable insect screen

  • Exterior of aluminium in "grey friars" colour

  • R-value of 0.40**

The VCM is watertight for pitches between 0-60°, though raising the installation pitch to 10° may be preferred for the best aesthetic appearance. Below this pitch you are likely to experience water ponding on the glass.

** R-value (m2 K/W) data based on NFRC simulations at 90° installation pitch (nominal skylight size 1200mm x 1200mm)

Convenient controls

Choose and order your control option when ordering your VCM low-pitch opening skylight (sold separately):

  • ZCT 300 control rod when installed out-of-reach.
  • ZZZ 212 handle when installed within reach.
