170 Sound & Crack Isolation Mat
Proven sound and crack isolation — now precision cut sheets for better installs
The 170 Sound & Crack Isolation Mat sets a new standard for acoustic performance and installation efficiency. Engineered to reduce noise transfer and protect tile and stone finishes from substrate movement, the updated system introduces precision-cut sheet formats alongside optimized roll sizes—giving installers and specifiers greater flexibility without sacrificing performance.
The new sheet format features automated, precision-cut beveled edges that create tighter seams, cleaner transitions, and a smoother finished surface. Sheets lay flat immediately with no roll memory or acclimation time, reducing waste and speeding installation. Additionally, lightweight, palletized packaging improves ergonomics and makes single-person handling of sheets easier on the jobsite.
With multiple thicknesses to meet a wide range of acoustic requirements, up to 94% post-consumer recycled content, and independent testing that exceeds code requirements, the 170 Sound & Crack
Isolation Mat delivers trusted performance for residential, and commercial floor assemblies—backed by a 25-year LATICRETE system warranty
