This is a retro-fitted combustion air vent with an external cowl for boilers, stoves and fires. The external cowl is designed to offer protection against excessive weather and has the advantage of alleviating air blasts through the cavity.
The internal panel is draught reducing and this allows air to be evenly dispersed in to the room, thus increasing your comfort, while the external baffle prevents the travel of moisture across the cavity.
This vent is so easy to paint or wallpaper, allowing you to match the features of the room. Installation is very simple too and the interlocking components make aligning and positioning easy. The grille is embossed with the reminder 'DO NOT BLOCK' for your safety.
To slow down the impact of sunlight, both the external grille and cowl have been UV stabilised. And the component has been HETAS approved for use with solid fuel applicances.
