The Redland Cambrian Slate 4.5K Thruvent Tile With Underlay Seal incorporates ventilation within your roof pitch at a low or high level. This 4.5k vent is also suitable for roof space ventilation, mechanical extraction and soil vent termination for two storey housing. The black underlay seal included should always be installed to maintain the integrity of the roofing underlay.
Available in a range of colours including Heather, Langdale Green, Pre-Weathered & Slate Grey, the ThruVent Tile itself is made from concrete with a PVC ventilation unit & cap and the underlay seal is made from black polypropylene.
Installation: Where ThruVent Tiles are used in combination with insulation between the rafters, ensure that the pipe on the underside is clear of the insulation, by cutting the pipe where necessary.
ThruVent Tiles are not suitable for hot flue gases, please use the Gas Flue Ridge Terminal. For soil pipe termination do not install within 3m horizontally and 900mm vertically of an opening, e.g. roof windows and roof space ventilation.
To achieve the specified roof space ventilation the ThruVent tiles should be spaced as recommended: ThruVent: 4.5 k, Roof Space Ventilation: 5000 mm_/m, ThruVent Spacing: 0.9m or ThruVent: 4.5 k, Roof Space Ventilation: 10000 mm_/m, ThruVent Spacing: 0.45m.
Minimum and maximum pitch will depend on the profile and surface finish. Minimum and maximum headlap will depend on the tile profile. To achieve the specified roof space ventilation the ThruVent tiles should be spaced according to the table in the technical section.
Flexible Pipes (not included) are available for connecting to a 110mm soil vent pipe or mechanical ventilation duct.
