Sealing of window and door perimeters in a closed cavity wall, solid masonry wall, insulated concrete form walls (ICF) or other constructions where the window or door is inset into the structural opening and not projecting from the backing wall.

Cavity wall reveals must be closed off with a proprietary thermal cavity closer, blockwork or similar return to the outer leaf. Existing cavity and solid masonry wall reveals may need to be made good. Damaged or excessively undulating masonry should be levelled off with sand and cement render to provide a flat as possible surface. TP650 Trio is applied directly to the head an jamb of the frame immediately prior to the final installation of the window or door. The cill section of TP650 Trio is applied to the substrate of the structural opening and bonded with illbruck SP525.


An impregnated, pre-compressed Multi-functional Sealing Tape. Comprised of open-cell polyurethane soft foam, impregnated with flame-retardant synthetic resin. The vapour diffusion properties are achieved through unique, one-sided patented side impregnation. The impregnation protects the tape against mould and fungi growth. TP650 utilizes the property of water-vapour permeable sealing, making it less permeable inside than outside.

Features and benefits:

  • Airtight.
  • Watertight.
  • High movement capability.
  • Low thermal conductivity.
  • Breathable.
  • 25 year life expectancy.
