A flexible visco elastic membrane 1.2mm thick, installed between two plasterboards is the most efficient and cost effective way to reduce noise transmission through a partition wall.
Very economical and easy to install it will give, for a typical 148mm thick partition wall, a 6 star rating with a Rw62 and Rw + Ctr = 55db, exceeding BCA minimum requirements between attached dwellings.
Visco Elastic Membranes are a high performance noise barriers that deliver exceptional performance utilising layer membranes to reduce noise in a variety of applications i.e. inside dry wall.
