Perimeter Acoustic Isolation Strips

Why choose Farrat Perimeter Acoustic Isolation Strips?

Farrat Perimeter Acoustic Isolation strips are used in conjunction with Acoustic Floating Floors to maintain the isolation of the floating element by preventing it from touching the surrounding walls or other isolated structures.

They are fitted as the first step in the installation process for all types of Acoustic Floating Floors and have further applications in assisting with setting the finished floor level and clearing perimeter concrete snots.

All options in Farrats Perimeter Isolation Strip range perform the function of providing a resilient separation between the floating element and the surrounding structure in an Acoustic Floating Floor construction. However each have different features to assist with installation.

Typical application of Farrat Perimeter Acoustic Isolations Strips:
Example Site Applications:

Step 1

  • Align either the top of the strip level of the strip level or the tear-off line with the finished floor datum and adhere to perimeter walls.
  • Farrat ISOFOAM ISO3 Perimeter Acoustic Isolation Strips have self-adhesive back to speed up installation.

Step 2

  • It is not always necessary for the strip width to extend all the way to the structural slap level, but it must extend at least 25 mm below the underside of the floating element (including formwork).

Step 3

  • Perimeter Acoustic Isolation Strips should be butted tightly together and installed anywhere that the floating element would otherwise touch existing structure. This includes penetrations through the floating element.

Step 4

  • Once the floating element element has been installed, ensure that the isolation strip is visible and clear of debris around the entire perimeter.
  • Clear away concrete snots and/or remove tear-off strips as necessary.


Self-adhesive back allows for fast installation & easy positioning.
