A horizontal version of ARC Party Wall DPC is available, which includes additional width of DPC which can be lapped back to the inner leaf, negating the requirement to install a separate cavity tray above.
ARC Party Wall DPC enables the closing of an external cavity at either party wall or party floor junctions where building regulations require the use of mineral wool closer for acoustic insulation purposes.
Manufactured from non-combustible rockfibre mineral wool insulation and sleeved in colour coded polythene for on-site identification and protection. The ARC Party Wall DPC includes an integral DPC, satisfying any requirement for a DPC to be installed between the barrier and external brickwork.
