How to soundproof a shared party wall

Video Description

How to soundproof a party wall in a 1960s semi-detached home the right way. We treat every noise path (party wall, suspended floor void, ceiling void, chimney stack & fireback, RSJ/steel beam, window wall, and an upstairs paramount board partition) to stop neighbour noise, airborne and flanking transmission. You’ll see why dot & dab plasterboard and quick-fix panel/clip systems often fail, and how our four-step soundproofing method (find holes → open voids → sound-deaden → isolate/add mass) delivers a real reduction so you can stay in the home you love. Materials & methods: viscoelastic sound-deadening membrane, 10–20 mm rubber isolation, RW3 Rockwool, resilient bars/channels, honeycomb/constrained-layer board, 15 mm acoustic plasterboard, acoustic sealant/adhesives, moisture membranes, acoustic secondary glazing. Includes our “tuck it up & tuck it down” approach for floors/ceilings.
