Laticrete’s high-performance acoustical underlayment, the 170.5 Sound & Crack Isolation Mat, muffles noises through hard surfacing materials. The 5mm-thick, rubberized membrane, comprised of 88.5% post-consumer recycled materials, also helps prevent substrate cracks of up to 1/8 inch from transferring to the finished floor, according to Laticrete. For interior use only, the Greenguard-certified underlayment applies quickly and easily to concrete, mortar beds, exterior glue plywood, cement backer board, cement terrazzo, cement tile, and stone, the manufacturer claims.
