This creates a slow expanding pre-compressed, expanding foam tape that is used to resist weather ingress in fenestration, roofing, and other construction applications. Its visco-elastic property offers noise/vibration damping while its impregnated foam structure provides an energy efficient thermal barrier. PHS TRS allows some movement of the structure whilst ensuring that the airtight seal remains constant.


  • BG1 Water-tight seal to driving rain at 600Pa,
  • Good air-tightness if used compressed,
  • Acoustic and thermal insulation,
  • Vapor permeable,
  • Easy and clean to apply,
  • Improves energy efficiency in buildings,
  • Seals against uneven surfaces,
  • Accommodates joint movement
  • Fire retardant, self-extinguishing,
  • Easy to quantify usage.
