THS

Flat cowlThe cowl is fitted at right angles to the roof cladding and can therefore be used on different roof pitches. Manufactured from powder-coated, galvanised sheet steel, in the standard colours of black and brick red. The spiral pipe connected to the cover is insulated with 30 mm rockwool. The TUS under-plate, for fitting inside the roof, is included. This underplate prevents water-damage via the roof aperture if there is leakage on the outside of the roof. The under-plate should not be used if the roof is only covered with roofing felt.
