ARC’s Party Wall Cavity Stop Sock is designed for use at the party wall junction; fitted in the external wall cavity, with a minimum 50mm overlap either side of the party wall cavity. At 250mm wide, ARC’s PWCSS range is suitable for use with party wall cavities up to 150mm wide. These wider barriers do not require a compression fit, and are supplied with a 5mm compression to allow for site anomolies.
