SikaTile®-700 Sound Shield PNS is a 90 mil (2.3 mm), thin, flexible, self-bonding, fabric reinforced, load-bearing membrane that reduces sound transmission and isolates ceramic and natural stone tile from cracks in the substrate. Suitable for both full and partial coverage applications. SikaTile®-700 Sound Shield PNS reduces the transmission of impact and airborne sound through floors when installed under ceramic tile, stone, or wood floor coverings. It is also a crack isolation membrane that exceeds the requirements of ANSI A118.12 and protects tile from in plane movement up to 3⁄8” (9.5 mm). Its strong self-adhesive backing and uniquely designed surface provide secure bonding for all types of ceramic, natural stone, and terrazzo tile. After application, ceramic tile or stone can be installed immediately using appropriate SikaTile® polymer-modified cement-based mortar. Additionally, glue-down wood flooring can also be installed with approved urethane adhesives.
