Browse Forums General Discussion 1 Mar 20, 2013 1:55 pm My current house in Perth was built with the standard local practice of concrete slab, double clay brick external walls, single clay brick internal walls, gyprock ceiling and insulation batts. I'm disappointed with the poor noise insulation between rooms. I recall, during building, that the internal bricks were just tacked together at the corners with cement rather than being fully mortared like an external wall. I was told, at the time, that this was to give the cement float something to cling to. Contrast this with a mates home that has excellent noise insulation. His internal walls were fully mortared. Am i right in thinking that a fully mortared wall offers significantly better sound retardation? Re: internal walls and sound insulation 2Mar 20, 2013 8:11 pm I have yet to see a wall 'tacked together at the corners' but I feel the render would fill enough to deaden sound Remembering back to my own experiences in the building industry in SA where internal walls were perforated bricks laid on edge, with the perforations saving clay in the manufacture and provided a key for rendering, seemed to work OK. Today with brick veneer, internal walls are mainly timber stud-work clad each side with gyprock, which wouldn't compare with what you have.
