Technical information
Roof windows are an easy and effective way to bring natural light into a habitable space where there is a pitched or flat roof.
Gaps between the window frame and rafter/trimmers should be filled with PIR insulation or proprietary insulation collars such as the VELUX BDX (click here to see full installation instructions).
Sun tunnels are an easy and very effective way to bring natural light into a concealed space where natural light is not normally possible such as hallways and bathrooms, reducing the need for artificial light. Sun Tunnels can be installed on both pitched and flat roofs and help improve the daylighting within a home.

Hints and Tips
Windows should be secured in place using supplied fixing tabs screwed to doubled up rafters and trimmers.
Ensure you have the correct flashing type to suit the chosen roof coverings.
When plasterboarding around the inside of the roof window, the plasterboard should not come into contact with the rafters/trimmers. Either PIR or, if the space is to small, multi foil insulation should be located between the two surfaces to stop cold bridging.
Sun tunnel collectors should be installed in a position that receives the largest quantity of direct sunlight.
