Composed of dense post-consumer rubber, Mapesonic RM provides the dual uses of sound reduction and crack isolation. Available in thicknesses of 3/16" or 5 mm (Mapesonic RM5) as well as 3/8" or 10 mm (Mapesonic RM10), the dense rubber reduces impact noise when used as an underlayment as part of a tile or stone installation system. In fact, Impact Insulation Class (IIC) acoustical testing yields results of 50 to 64, depending on floor/ceiling assembly.
In addition to noise reduction, Mapesonic RM helps to prevent existing and future in-plane substrate cracks with movement up to 1/8" (3 mm) from transmitting through ceramic tile and natural stone. The premium rubber underlayment passes the “High Performance” requirements of ANSI A118.12, Section 5.4. And because it contains 82% post-consumer and 1% pre-consumer recycled content, it is GreenCircle certified.
“With this new premium rubber underlayment, MAPEI is helping neighbors live and work in peace,” Moste said. “And Mapesonic RM carries a lifetime warranty when it is used as part of a high-performance MAPEI installation system.”
