Glidevale IN-LINE slate ventilators have been designed to provide an aesthetic and unobtrusive solution to roof space ventilation. They can be used at low or high level where the roof construction does not allow eaves or ridge ventilators to be used, or where complex roof shapes do not allow effective cross ventilation. 


Simply installed as part of the normal slating process. Easily converted for use as SVP or mechanical extract terminals compatible with tiles from these Manufacturers: Marley/Cedral, Redland, Cembrit, SVK UK
