Iso-Sill™ Plate Isolation stays permanently elastic and unaffected by water.

Acoustic ‘flanking’ can seriously degrade the acoustic performance of a wall assembly. Iso-Sill™ ™ is used to help prevent structure borne noise from transmitting through the wall into the areas above and below the partition. Iso-Sill™ ™ is a permanently resilient gasket that decouples wall assemblies from the building structure to reduce the transfer of sound and vibration.

 Iso-Sill™ ™ Plate Isolation is manufactured with reclaimed rubber and is formulated with high damping acrylic polymers making it a “Green” product for LEED projects. The Iso-Sill™ ™ Isolation Plate is manufactured to carefully controlled density standards for trusted long term service.

Iso-Sill™ ™ Isolation Plate can be installed with mechanical fasteners, polyurethane based construction adhesives, or a variety of thin-sets and mortars. Iso-Sill™ is impervious to water, most chemicals and temperature change. Iso-Sill™ ® will not rot or support mold.  Iso-Washers for installation are also available through AcoustiGuard® – WILREP LTD.
