Manthorpe Mini Castellated Tile Vent (GTV-MC)

This Manthorpe Mini Castellated Tile Vent is compatible with the following manufacturers / tiles:

Redland 49
Marley Ludlow Plus
Sandtoft Standard Pattern
Forticrete V2

The smallest of our in-line roof vents, this Manthorpe Mini Castellated Vent is cleverly designed to interlock perfectly with 230mm x 390mm castellated (square top) roof tiles from four of the top UK manufacturers. These vents can be used for simple roof space ventilation, or can be quickly adapted for mechanical extract or soil stack applications.

A neat, inconspicuous grille on the vent's upper surface keeps large insects and debris out of the roof space. Any rainwater which enters the grille is funnelled out onto the roof, through two polypropylene outlets at the base of the vent. A 110mm diameter spigot on the rear of the roof vent delivers 5,000mm2 of free air flow. The whole unit is compact and easy to install, occupying the space of one single roof tile. Manthorpe’s Mini Castellated Vents will operate on a pitched roof as low as 17.5 degrees.

This simple, compact ventilation solution requires no special fixings or batten cuts. These roof vents are exceptionally versatile and can be quickly customised for extract operation with Manthorpe flexible piping. The external appearance is neat and appealing, with the Manthorpe Mini Castellated Vents being virtually unnoticeable from ground level. The vents can be ordered in a choice of four common roofing colours from Ashbrook Roofing Supplies.

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).
