Manthorpe GTV PT Plain Roof Tile Vent

The Manthorpe In Line Plain Tile Vent is designed to provide a quick and simple solution to the problems of roofspace ventilation and mechanical extraction / soil stack termination through a plain tiled roof.

The vent is quick and easy to install, taking the place of a 3 plain tiles with no need to cut the battens.

The inline profile helps to maintain an unbroken appearance to the roofline whether used at high or low level.

The tortured path through the internal weathering geometry is designed to maintain a constant airflow gap of 7,000 m square metres whilst channelling any water ingress out of the vent and on to the roof covering below, with the 4mm louvred grill and placed to prevent the entry of debris and large nesting insects.

Available in a range of colours and finishes to suit most styles of modern concrete and traditional clay plain tiles from all major UK and Irish tile manufacturers, these vents will blend into either new or existing plain tiled roofs.

Application:

  • The vent tile is laid in a broken bond format taking the place of 3 individual plain tiles across 2 courses
  • Once the position of the vent is marked,the underlay can be cut to allow for the base outlet, at which point the unit can be aligned with the tile course below and nailed in place
  • Tiling can then be resumed,fitting the adjacent tiles around the vent
  • The vent outlet is designed to penetrate through the roofing underlay between the tile courses, meaning there is no need to cut or trim the battens, even when laid at the lowest batten gauge of 88mm (when using 38mm roofing battens)
  • NOTE: When using the vent for mechanical extraction, the pipe adaptor is fitted from inside the roof space
