MAPEI’s Latest Membrane Brings You Peace and Quiet (April 01, 2008)

With new Mapesonic SM, the annoyance of airborne and impact sound transmitted through floor/ ceiling assemblies is dramatically reduced. The premium “peel-andstick” membrane not only offers an STC rating of 73 and IIC rating of 69–but also provides in-plane crack isolation. Mapesonic SM is white to optimize visibility on the job site. Printed layout lines help reduce the labour associated with measuring and cutting.
