Manthorpe Double Roman Tile Vent - GTV-DR

This Manthorpe Double Roman Tile Vent is compatible with the following manufacturers / tiles:

  • Redland Double Roman
  • Marley Double Roman
  • Sandtoft Double Roman
  • Russell Double Roman
  • Lagan Double Roll

From our latest range of roofing supplies, this Manthorpe Double Roman Tile Vent offers an incredibly neat and efficient, profiled roof vent solution to match a wide range of double roman roof tiles. These vent tiles are easy to install into the roof space. The roof vent is carefully designed to provide high-volume airflow, while channelling any incoming rainwater straight back out onto the roof.

The external grille is manufactured from uPVC, with 4mm slats to keep out insects and debris. The grille’s low-profile design is discreet, and barely visible from ground level. The grille feeds air into a polypropylene chamber which is specially angled to expel incoming rainwater back out onto the roof. The tiles feature two inbuilt channels to efficiently dispose of incoming water. A 48.25mm outlet on the rear of the tile delivers 10,000mm2 of free-flowing air into the roof space.

This in-line, Manthorpe roof vent is a simple, attractive solution that can be easily adapted for mechanical extraction or soil stack termination. As part of our comprehensive range of roofing supplies we stock Manthorpe Double Roman Tile Vents in four classic colours. This compact vent is compatible with double roman tile profiles from five leading manufacturers.

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).
