AIM Cavity Fire Closers
The AIM Cavity Fire Closers have been designed to close cavities for fire, thermal and acoustic purposes; it reduces cold bridging when closing cavities at door and window frames.
The primary use of a cavity fire closer is to stop fire escaping from or entering into the external wall cavity around openings in the building envelope. This helps ensure that the detailing around the opening provides a protected means of escape from the building in the event of a fire.
AIM Cavity Fire Closers can be used around openings such as a window or door. They can also be used as a cavity barrier within extensive cavities where the cavity, within the wall structure, is in excess of 20m long.
