TP650
Trio

TP650 is an impregnated, pre-compressed multi-functional sealing tape. It is comprised of open-cell polyurethane soft foam, impregnated with flame-retardant synthetic resin. The different vapour diffusion properties are achieved through a unique, one-sided patented side impregnation. The impregnation also protects the tape against mould and fungi. TP650 utilises the property of water-vapour permeable sealing, making it less permeable inside than outside (inside tighter than outside principle).

Usage/Purpose

TP650 is used for sealing the perimeter joints of windows and doors against driving rain and provides airtightness and thermal insulation, thereby maintaining the energy performance of the window/door. Easy application with single product, complying with BS8213-4:2016 Code of Practice & GGF Guide to Good Practice – Installation of replacement windows and doors.

  • Suitable for new-build and replacement installations
  • Maintains the energy performance of the window/door
  • Driving rain resistant to 600 Pa, also providing thermal and acoustic insulation and airtightness in one product
  • Quick and easy application
  • Complies with BS8213-4:2016 CoP for survey and installation of windows and external doorsets
  • Complies with GGF Guide to Good Practice – installation of replacement windows and doors
  • Vapour permeable
