Description
Manthorpe GTV CURV Cowled Universal Concrete Interlocking Roof Tile Vent Red / Grey / Terracotta / Brown
The Manthorpe Cowled Universal Roof Vent is designed to provide a quick and simple solution to the problems of roofspace ventilation and mechanical extraction / soil stack termination through a wide variety of concrete interlocking roof tiles.
It is especially useful on jobs where the installer may not know what the roof covering is: Designed to suit many large and small format concrete interlocking tiles, both flat and profiled in design, from 15x9s to large flat profiles such as the Marley Modern to deep bold roll styles of roof tile.
The Manthorpe Cowled Universal Roof Vent Tile is fitted with a versatile flashing skirt which can be dressed to match the relevent profile of the roof covering and comes with an adhesive mastic backing which securely seals the flashing down to the roof tile.
The hooded cowl protects the opening from the elements whilst providing an airflow path into the roofspace. An integral 4mm louvred grill within the cowl prevents the entry of debris and large nesting insects.
When using the vent for mechanical extraction, soil stack or vent pipe termination, the rear spigot is stepped to allow for 4" round, 5" round or a 6" oval connection.
The 4" connection can be joined to one of the Manthorpe range of GRPA Flexible Pipes to continue the ducting further into the roofspace.

Fixing
- The flashing skirt is designed to be dressed over the course the vent sits on, to allow for the penetration below, an entire tile can be removed or the corners of two adjacent tiles can be trimmed to create an opening.
- In both instances a strip of tile/slate the same depth as the headlap should be left to support the rear of the flashing.
