LATICRETE 170 Sound & Crack Isolation Mat
Premium Sound Reduction Underlayment & Crack Isolation Membrane for Tile & Stone Flooring
The LATICRETE 170 Sound & Crack Isolation Mat is a premium acoustic underlayment and crack isolation membrane engineered to create quieter, longer-lasting tile and stone installations. Designed to reduce impact noise while protecting finished floors from substrate movement, this high-performance underlayment is ideal for residential, commercial, and multi-family construction projects.
Available in 3mm, 5mm, 10mm, and 12mm thicknesses, the 170 Sound & Crack Isolation Mat is offered in both traditional rolls and lightweight precision-cut sheets, allowing installers to choose the format that best fits their project.
