Opening Flat Roof Skylight


Designed for flat roofs, the VCM Manually Opening Skylight offers  free Daylight and Natural Ventilation. The pre-installed Insect Screen adds the benefit of keeping mosquitoes and flies out during the warmer months. A handle or control rod may be purchased separately to operate the window.

Alternatively, why not upgrade to the VCS Solar Powered Skylight featuring a solar panel that captures daylight to recharge a concealed battery. The added convenience of remote control and built-in rain sensors make this the ultimate Skylight solution.

Please note – Inner glass dimension is approximately 200mm less then the overall size.
