Description:

VELUX Flat Roof Rigid Sun Tunnels are the ideal solution for bringing natural light into areas of the house where it is either not possible or not appropriate to install a flat roof window.

VELUX Flat Roof Sun Tunnels can transform a bathroom, cupboard or office space, flooding the room with natural light. When a VELUX roof window or flat roof dome is not possible, these innovative systems are the perfect choice.

Key Features:

• Recommended for tunnel lengths from 0.8 to 6 m between the roof and ceiling.
• The 1.7m long rigid tunnel should be used when greater lengths- in combination with ZTR extension sections- are necessary and to ensure adequate daylight levels are obtained. It is supplied with 2 x 45 degree bends. 
• Can be extended to distances up to 6 meters.
• Rigid tunnel has a diameter of either 35cm or 25cm.
• Super reflective coating along the interior of the tunnel provides a 98% internal reflection rate.
• An easy-to-assemble diffuser comes complete with a frosted polycarbonate insulating frame.
• Roof module in PVC and an acrylic dome.
