THB

Profiled cowlThis cowl is shaped so as to fit over a standard double-lap concrete roof tile (THB 160), or over two tiles (THB 200). The 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 matting. The TUB under-plate, for fitting inside the roof, is included. This under-plate 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.
