What thickness should I choose?
The 170 Sound & Crack Isolation Mat is available in 3mm, 5mm, 10mm, and 12mm. Thicker profiles provide greater sound attenuation and are ideal for multifamily and commercial applications where impact noise reduction is a priority. The 3mm option is well-suited for residential projects where floor height buildup is a concern.
What substrates is the 170 Sound & Crack Isolation Mat compatible with?
The 170 Sound & Crack Isolation Mat is rated for use over concrete, mortar bed, cement backer board, exterior glue plywood (interior only), and ceramic tile and stone.
What is the IIC rating?
The 170 Sound & Crack Isolation Mat achieves a ΔiIC of up to 28 per ASTM E2179 and up to 44 per ASTM E492 and E989, depending on assembly configuration. IIC stands for Impact Insulation Class — a standard measure of how well a floor assembly reduces impact sound transmission between floors.
Can I use the 170 Sound & Crack Isolation Mat in commercial projects?
Yes. The 170 Sound & Crack Isolation Mat is ASTM C-627 rated and meets ANSI 118.12 and 118.13, making it suitable for a wide range of commercial and institutional flooring applications.
