In addition to the best selling range of smooth faced ventilators, the Manthorpe in-line plain tile vent is now available with a granulated finish, which helps it to blend in when fitted on a roof covered with sand faced plain tiles.  The vent is quick and easy to install, taking the place of 3 plain tiles with no need to cut the battens, providing a simple solution to the problems of roof space ventilation and mechanical extraction.  Available in four granulated coloured to suit most styles of sand faced plain tiles from the major tile manufacturers.
