supplied with the roof curb. This seal must be glued by the installer on the roof curb to avoid metal

Once installed and fastened to the roof structure, the outside wall of the curb must be fully integrated in the roof
insulation.

ROOF CURB
The main purpose of the roof curb is to provide weatherproof passage,
supply and return air down to the building from the ROOFT@IR.
In this way, all connections (air, electricity) to the building are not free
above the roof. The curb provides a perfect roofing thermal insulation
and weight distribution between the ROOFT@IR and the building.
The roof curb should be used for a downward configuration at supply
and return air. The roof curb guarantees the perfect weathertight sealing
between the building structure and the appliance.
Two versions are available:
knocked-down and non-adjustable version
¢
This fixed roof curb, as an option, is supplied in kit form. Ask your sales representative.
