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.
