4.2 Material and components
The roof curb is manufactured from powder-coated galvanised sheet steel. The spiral duct connected to the cover is in-
sulated with 30 mm mineral fibre. Two 3 m cables are included, as well as the TUS base plate which is fitted on to the
inside of the roof. This base plate prevents water-damage via the roof aperture if there is leakage on the outside of the
roof.
The base plate should not be used if the roof is only covered with roofing felt.

5.1 Design
Roof curb with a flat covering plate, which is fitted at right angles to the roof cladding and can therefore be used on dif-
ferent roof pitches. Roof curb TOS is designed to fit the TFSR roof fans.
5.2 Material and components
The roof curb is manufactured from powder-coated galvanised sheet steel. The spiral pipe connected to the cover is in-
sulated with 30 mm mineral fibre. Two 3 m cables are included, as well as the TUS base plate which is fitted on to the
inside of the roof. This base plate prevents water-damage via the roof aperture if there is leakage on the outside of the
roof.
The base plate should not be used if the roof is only covered with roofing felt.
6 Mounting of the seal plate TUB/TUS
A lower plate must be installed on all roof bases unless the only cladding is roofing felt.
6.1 Roof preparations
Where there is an underlay of foil, cloth, thin board or similar, extra supports are nailed between the roof trusses (under
roof base) and the TUB is fitted on these, figure 1.

6.2 Mounting
1. For tiled roofs : Remove one or two roof tiles (depending on the size of the covering plate). Make a hole in the roof
base corresponding to the dimensions of the insulated pipe, in the centre of the recess.
For profiled roof cladding (not removable): Make a hole corresponding to the external dimensions of the TUB in the
roof cladding, and a hole corresponding to the insulated pipe in the roof base.
For roof bases without roofing felt, go directly to point 3.
2. The TUB is placed (collar upwards) under the roofing felt at the upper edge and along the sides, and on top of the
roofing felt at the lower edge, figure 2 and figure 5.
