A parge coat for increased airtightness to optimise sound & thermal performance. Parging of masonry walls, prior to drylining, is a commonly used method of improving the thermal & acoustic performance by minimising air leakage through cracks, unfilled joints & block porosity. Buildings that are well constructed, with a good standard of airtightness, will benefit from enhanced energy & acoustic performance, lower heating costs, reduced CO2 emissions & greater comfort for its occupants. Key facts – what’s changed Soundcoat Plus replaces Sound Coat to deliver even more performance benefits. It has been formulated to enable application on to aircrete blocks, as well as aggregate, & is now part of nine Robust Detail masonry wall specifications, including separating walls incorporating aircrete blocks. Used in Robust Detail wall construction E-WM-3, E-WM-4, E-WM-5, E-WM-6, E-WM-10, E-WM-11, E-WM-12, E-WM-13, & E-WM-16
