Aero Core Anti Draught Ventilators

Installation Advice

Core anti-draught ventilators can be installed in new builds, but benefit the installer most when used in existing walls
To fit in existing cavity walls, make a hole through the full cavity wall using either a 5" or 6" core drill, whilst ensuring a small incline towards the outer wall. Remove brickwork debris to fit the vent
Large flanges around the external cowl and internal grille allow minor irregularities to be covered easily and also adequate fixing
An external cowl will push onto the sleeve and can be silicone sealed to face or screw fixed
