More Information

Perimeter Flanking Band – FB8 is an absolute essential in floor soundproofing systems and one that is often overlooked. Perimeter Flanking Bands are to line the perimeter of any room that is using rigid materials that would come into contact with the walls. It acts as a buffer, one that reduces Flanking Transmission, by creating a barrier between floor and wall. It is to be installed along with any installation of a new subfloor in timber builds, even if you plan to install a woven carpet. It is for when you are installing any hard floor finish such as the examples below. These are because a timber overboard is required with some of our flooring options.

  • Engineered wood
  • Laminate
  • Luxury vinyl tile
  • Vinyl
  • Ceramics

Screeding also benefits from the use of a Flanking Band as it helps to decouple the new floating screed from being in immediate contact with the walls.


  • 8mm x 150mm x 50m
  • Vital decoupling for flooring systems to separate floor and wall
  • Suitable for concrete screeding applications, and when installing hard floor finishes
  • Also suitable for timber structures when installing a new subfloor, and when installing hard floor finishes
  • Closed cell foam structure
  • Plastic apron to keep an airtight seal with adhesive
Perimeter Edging Strip should be applied around the perimeter of each room to where hard flooring comes in to contact with the adjacent wall, so with the fitting of new timber flooring it should be installed at joist level to the final floor finish level, in acoustic under screeding in concrete constructions, you will want to make sure full coverage is available to reduce contact with the adjacent concrete walls.
When all floor layers are butt against the Perimeter Edging Strip it reduces flanking transmission by creating a barrier between for and wall for impact sound to transfer in to, instead of directly in to the adjacent walls – helping to improve the soundproofing quality of the floor. Negating this can lead to failure of acoustic tests in most cases and is difficult and costly to fix in retrospect.
It requires bonding to the wall to make sure it has a secure fit, then the plastic apron with the self-adhesive strip is applied to the floor to create an L shape.

Installation Guide

Install Perimeter Flanking Band where there are to be rigid surfaces coming into contact with the wall.

Screeding will also be in the same application.
