Apache
The Apache is a free control vapour barrier slip joint for penetrations and capping. It is used to prepare sub-floor bases in tandem with the laying of DPM membranes to protect penetrations by underground services, ducts and piles.
SPECIAL NOTE:
Thanks to the team at Ignite Architects for specifying this system in a commercial subfloor base and the quality installation from the team at Mansion Civil.
