Manthorpe Castellated Tile Vent - GTV-CS

The Manthorpe Castellated Tile Vent is easy to install in place of a standard, square-top, concrete roof tile. The tile surface features an integral, louvred grille which feeds a large volume of air directly into the roof space. A carefully engineered chamber on the reverse of the vent diverts any incoming rainwater out through two internal channels onto the roof.

This item is compatible with the following manufacturers / tiles:

  • Marley Ludlow Major
  • Sandtoft Lindum
  • Russell Cheviot
  • Lagan Square Top
  • Redland Renown (with vent modification)

This unobtrusive roof vent is simple to install and can be quickly adapted to operate as a mechanical extract or soil stack vent. Performance is impressive, with the unit delivering 10,000mm2 of fresh air directly to the roof space through a 48.25mm outlet. Rainwater ingress is effectively expelled through the tile’s polypropylene water channels. The low-profile, exterior grille keeps insects and debris out of the roof space. The vent is barely visible from the ground, making this an ideal ventilation option for a compact, modern build.

Independently Tested to BS 8612

Following the increased use of dry fix systems courtesy of these updates to BS 5534, a brand-new standard BS 8612 was introduced in February of 2018 to better control the design and material construction of dry fix systems. Manthorpe’s range of dry fix products have been independently tested to conform with the requirements of BS 8612, performance data for the tests conducted on these products is available upon request.

By far the simplest, quickest, and most cost-effective way of complying with the new standard is to join the switch to dry fix methods of roofing. Manthorpe's dry fix systems provide a high performance, easy to fix and maintenance free solution which can not only speed up the job on site, but also offer long term financial benefits.

The Bat Ridge Roost provides a habitable roost space for small crevice-dwelling bat species found in the UK.

Designed in association with the Bat Conservation Trust as part of their Roost Partnership scheme the product is a self-contained, externally mounted unit which offers no means of access for the bats to enter the roof space or the property. The Bat Ridge Roost also acts as a ridge end cap and is optimised to work in conjunction with the Manthorpe SmartVerge Polypropylene handed and ambidextrous dry verge systems (alternatively, could also be used with third party dry verge, traditional verge tiles or mortared in verge details).
