Periscope vents are used in block and beam installations and for sub floor ventilation in timber floors. They have a cast iron air brick fitted externally and an integral internal plastic grille.
Cavity wall sleeves allow air into rooms for ventilation. They are fitted with internal baffles to reduce light and draughts. They are supplied with 1,2 or 3 cast iron air bricks externally depending on size and require an additional cast iron vent grille for the room they ventilate. We would recommend using Daisy pattern (DAY104 and DAY107) grilles with mesh for the CAV3 and CAV6 respectively and the Heritage 9x9 grille for the CAV9.
The Windsor cast iron air brick fits into the modern plastic ducting and although available in just one size, the Windsor is an interlocking air brick that can be doubled or tripled to fit the larger sleeves and make a larger vent.
