Glidevale Cowl Vents


Glidevale profile dedicated G range tile, slate & flat roof ventilators are designed to ventilate through the roof slope and form an integral part of the roof covering.

The tile and slate 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 fire break walls obstruct airflow. They are particularly suitable for insulation upgrades when the roof covering is not being changed and recommended by the Energy Efficiency Partnership for Buildings as the solution for ensuring adequate ventilation is provided.

They are also used in complex roof shapes where effective cross-ventilation is not possible. The range of ventilators can also be used as soil vent pipe or mechanical extract terminals with separately supplied accessories.

  • Colour-matched to blend in with adjacent tiles as standard, making the ventilators almost indiscernible once installed.
  • Underlay opening protector, integral 4mm insect screen, and ventilator throat or extension sleeve meet design requirements of BS 5250.
  • Driving rain and deluge rain resistance demonstrated by test data.
  • Designed and developed under BS EN ISO 9001.
  • AA fire rating to BS 476: Part 3: 2004.

Product Range

    • Not recommended for high-level use as its large air capacity and wide spacing would tend to leave stagnant air pockets between units.
