Laticrete - 170.3 Insulating mat for acoustic and crack control

The 170 Acoustic and Crack Control Insulating Mat is a high-performance acoustic underlay system that dampens impact sound through ceramic tiles, stone and other hard surface coverings. It also minimizes the propagation of cracks from the support to the tiles, for cracks without movement of 3 mm (1/8 in) maximum. The 170 acoustic and crack control insulation mat is a 3 mm thick rubberized membrane that contains 88.5% post-consumer recycled materials.

• Eliminates the transmission of cracks from the substrate up to 3 mm (1/8 in) from transfer to the finished floor
• ΔIIC classification of 20 according to ASTM E2179 (see PHYSICAL PROPERTIES)
• IIC classification of 65 according to ASTM E492/E989
• Load carrier - “Light duty” classification according to ASTM C627/TCA
