FGT BR135 Foam Backer Rod
Sealing & Bonding Products


BR135 Foam Backer Rod is a closed-cell, polyethylene foam cord for use as a backing in glazing or expansion joints for elastomeric and other cold-applied sealants including silicones, polyurethanes, polysulphides, butyls, bitumens and acrylics. It is chemically inert and has an exterior 'skin' that acts as an effective bond-breaker strip, preventing it from staining or adhering to the sealant.

Sizes: Available in 100m rolls in various diameters from 6mm-50mm.

  • Highly flexible and provides permanent secondary seal behind joint sealant
  • Forms optimum sealant shape to minimise strain and adhesion stresses on sealant
  • Controls sealant depth preventing excess material usage
  • Promotes correct joint design and prevents three-sided adhesion
  • Closed-cell structure is resilient and prevents moisture absorption
