170 Sound & Crack Isolation Mat

The 170 Sound & Crack Isolation Mat is installed beneath ceramic tile and natural stone flooring to reduce impact sound transmission and isolate cracks caused by substrate movement in residential and commercial buildings.

The 170 Sound & Crack Isolation Mat is a high-performance underlayment engineered to reduce noise transfer while protecting tile and stone finishes from substrate movement. Designed with installer efficiency in mind, it is available in optimized roll sizes and precision-cut, beveled-edge sheets that deliver cleaner seams and consistent installation results. Its flat sheet format eliminates roll memory and acclimation time, while lightweight, palletized packaging improves handling and jobsite productivity. Manufactured in the USA with a high recycled content, this system provides a durable, sustainable, and warrantied solution for both residential and commercial flooring applications.

Features and benefits:

• Reduces noise transfer with multiple thickness options to enhance acoustic performance between floors.
• Provides crack isolation protection that helps prevent tile and stone finishes from cracking due to substrate movement.
• Precision-cut beveled sheet edges create tighter seams and a guided, puzzle-style installation for a smooth finished surface.
• Automated precision-cut sheet format ensures consistent sizing and reduced installation variability.
• Flat sheet design eliminates roll memory, allowing the material to lay flat immediately without acclimation time.
• Manufactured with up to 94% post-consumer recycled content to support sustainability and green building goals.
• Lightweight sheet options improve ergonomics, enabling easier single-person handling and enhanced installer safety.
• Tested per ASTM E2179 to meet IRC and IBC code requirements through independent verification.
• Meets ANSI A118.12 and ANSI A118.13 standards for crack isolation and sound reduction performance.
• GREENGUARD certified for low VOC emissions to support healthier indoor air quality.
• Improved pallet efficiency increases square footage per shipment, helping reduce logistics and freight costs.
