PRODUCT GUIDE
CV10K / CV20K Tile Roof Vents 
The Harcon low profile Cowl roof vent offers unobtrusive low or high level ventilation in tile roofs. The Cowl roof vent can blend almost invisibly to any roof: new build or conservation, because of Harcon’s unique colour and texture matching service.

The low profile Cowl roof vents incorporate a factory fitted round felt sleeve which penetrates the felt, so no extra sleeve is required.This round sleeve significantly reduces the felt tearing that can occur around rectangular spigots.

CP10K / CP20K Pipe Terminals
The COA1 adaptor can be simply site clipped to the cowl roof vent spigot, thus forming the pipe terminal for soil or extractor pipes.

The adaptor offers a 110mm dia. outlet as standard, this can be cut down to provide a 125mm dia. section if needed.
CT1C Flexitube
The Harcon flexitube is a high quality, durable product. It connects pipe terminals to 110mm dia. soil or extractor pipes; pressure tested in accordance with BS5250. Supplied compressed and netted with fixing clips.

FW1 Felt Weir
It is always necessary to cut and fold back the felt before fitting a roof vent. If this is done by following the Harcon fixing instructions no leakage will occur. However a ‘felt weir’ is available as an extra safeguard, it guides any condensation or rain water coming down the felt away from the vent opening. FW1 Felt Weir
