In-line® slate, tile and ridge ventilators

Glidevale In-line® slate, tile and ridge 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.

Features & Benefits

  • Unrivalled range of slate, tile and ridge profiles.
  • Narrow grille section gives an unobtrusive profile which does not interrupt the roof slope.
  • A choice of house colours, as standard, to blend in with adjacent tiles or slates.
  • Colour matching service for unusual tiles and slates, specials and old weathered tiles and slates.
  • Simply installed as part of the normal slating/tiling process.
  • Vents are easily converted into terminals for soil vent pipes or mechanical extracts with the use of a GV110 adapter.

Frequently Asked Questions

What type of rafter ventilators are available to vent an open eaves?

This depends on what amount of ventilation you require. Our RV625F supplies 25,000mm²/m whereas our RV601F gives 10,000mm²/m.  Our friendly technical advisors can advise the ideal product for your needs.

Are they easy to cut down if they are too wide for the rafters?

Yes, they are made from PVC and can easily be cut with a pair of scissors or Stanley knife.

Where can I purchase Glidevale rafter ventilators?

Either order from your local builders’ merchant or online on the BPD Store.

 Why do I need a fly screen type?

With the ventilator being fitted to an open eaves the fly screen will prevent nesting insects entering the airspace within the loft.

How easy are the ventilators to fit?

The fitting of rafter ventilators is very simple. However, when retrofitting them, there is an element of roofing and brick pointing in order to refit the bottom rows of tiles or slates. For more information, see our handy guide below. Always refer to the supplied fixing instructions when fitting.

Will they fit my roof?

They are available in 400mm, 450mm and 600mm widths and can easily be cut where needed to suit differing rafter centres.
