In-Line® Tile, Slate & Ridge Ventilators – Roofspace ventilation

Glidevale profile dedicated In-line tile, slate and ridge ventilators are designed to ventilate through the roof slope and form an integral part of the roof covering.

The slate and tile ventilators can be used at low level or high level where the roof construction does not allow eaves or ridge ventilators to be used such as where compartment walls or where fire break walls obstruct airflow. They are also used in complex roof shapes where effective cross-ventilation is not possible.

The In-line ridge ventilators are used at intervals with a range of manufacturers ridge tiles, on bedded and many dry ridge systems. The whole In-line range can also be used as soil vent pipes or mechanical extract terminals with separately supplied accessories.


  • Profile matched and colour blended in with adjacent slates, tiles and ridges as standard, making the ventilators almost indiscernible once installed.
  • Can be installed wherever they are required as part of the normal roofing process.
  • Driving rain and deluge rain resistance demonstrated by test data.
  • High nett free ventilation area and low airflow resistance allow for an optimum spacing to avoid stagnant air pockets.
  • Integral or supplied extensions sleeves ensure a clear air path from the roof void to the outside to meet the design requirements of BS 5250.
  • Integral 4mm large insect ingress screen.
  • An unrivalled range of slate, tile & ridge profiles plus colour matching service means that Glidevale offer an excellent service for heritage projects and listed buildings.
  • Designed and developed under BS EN ISO 9001.
