It complies with Approved Document E 2003 to the Building Regulations and with the requirements of Robust Details.
INSTALLATION
The AIM Party Wall Fire Closer should be installed in the external cavity wall with an equal overlap to either side of the party wall cavity. For 1 hour fire rating, the bearing on either side must be at least 75mm.
The Fire Closer should be fitted with the DPC overlap at the bottom. At the top of the Party Wall Fire Closers, the DPC should be extended to the inner leaf of the wall to form a cavity tray or sealed to the underside of the lintel.
