Party Wall DPC should be fitted during the brickwork/blockwork stage of the building process. The product should be fitted with the DPC against the inner face of the outer brickwork with the 40mm flanges on both sides. During vertical applications each length should be installed with 100mm flange at the bottom, with the next length forming a close butt joint over the flange. During horizontal applications the product should be supported by the wall ties that join the inner and outer leaf and is protected from above by the cavity tray system.

Party Wall DPC is supplied in strong polyethylene outer bags and should be kept dry on site prior to installing.

Due to the flexible nature of the product some local delamination may occur during handling. This does not however, detract from the performance of the product.

Insulation thickness: To suit cavities from 50mm to 150mm

*Other sizes can be manufactured to order

The mineral wool insulation used in the production of CCL Party Wall DPC and CCL Polycor FR achieves a fire classification of Euroclass A1 as defined in BS EN 13501-1. The DPC conforms to BS6515 (1984). The correct use of CCL Party Wall DPC and Polycor FR will exceed the requirement to provide a 30 minute cavity fire barrier as defined in Approved Document B of Building Regulations 2010 (2019) edition Table 3 of Appendix B.

The product has been independently tested adopting procedures and criteria from BS476: part 20: (1987) and achieved 1 hour fire resistance.

CCL Party Wall DPC complies with the robust details accepted to provide a solution which satisfies the Approved Document E (2003 Edition) of the Building Regulations relating to the transmission of sound.

CCL Party Wall T Sock is designed to minimise sound transmission and fire penetration through the wall cavity adjacent to separating floors.

Benefits

CCL Party Wall T Socks are supplied 10mm to 15mmm thicker than the cavity in which they are to be installed and friction fitted during the brickwork process.

During vertical installation it is necessary to place a length of damp proof course between the Party Wall T Sock and the outer leaf. The Party Wall T Sock can be supplied with a bonded DPC if required.

During horizontal installation, it is advisable to protect the Party Wall with a damp proof course or proprietary cavity tray immediately above with a minimum 100mm upstand.

Special attention must be paid to the joints to ensure that these are very closely butted. Cavity barriers may fail at the joints if a gap is left.

The Party Wall T Sock should bridge the whole cavity as shown ensuring a fully filled cavity under the required compression..

CCL Party Wall T Socks are supplied in 1200m lengths, normally 300mm wide with the thickness and party wall section dimensions manufactured to fit the specified cavity size and are available for cavities sizes ranging from 50mmm to 150mm.
