Mounting

Roof mounted, single pitched.

Guidance for specification option:

Vent can open to 90º or 140º. Can be supplied with an insulated kerb for fixing directly to the roof deck. The roofing membrane is dressed up the outside of the kerb to provide weathering. Alternatively, if a kerb is constructed as part of the roofing system, a kerb adapter can be supplied. Both kerb and kerb adaptors are manufactured from folded galvanized steel or aluminium, and can be thermally broken.

Roof mounted, double pitched.

Guidance for specification option:

Both pitches of the vent open to 90º. Can be supplied with an insulated kerb for fixing directly to the roof deck. The roofing membrane is dressed up the outside of the kerb to provide resistance to weathering. Alternatively, if a kerb is constructed as part of the roofing system, a kerb adapter can be supplied. Both kerb and kerb adaptors are manufactured from folded galvanized steel or aluminium, and can be thermally broken.
