Rigid tunnel TWR 14"
Sun tunnels for pitched roofs
The VELUX TWF/TLF flexi-tunnels and TWR/TLR rigid tunnels are designed to provide daylight into areas of the house such as corridors, stairwells, bathrooms, cupboards, etc where installation of a VELUX roof window is not possible.
Both systems incorporate a flat glass rooflight with *clear and clean coating and integrated flashing, a flexi or rigid tunnel, and a white trimmed double
glazed acrylic ceiling diffuser.
The flexi-tunnel has a tube which is designed for relatively short distances (0.4m-1.5m) between the roof and ceiling. It can be used where installations around obstacles within the roof space is required.
The rigid tunnel should be specified for lengths between 0.9m and 1.8m. For greater lengths up to 6m the rigid tunnel should also be specified in combination with ZTR extension sections which ensure adequate daylight levels are obtained.
It is supplied with 2 x 30° bends.
