This tape is comprised of open-cell polyurethane soft foam, impregnated with flame-retardant synthetic resin. The tape boasts a unique, one-sided patented side impregnation which 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).
This product is best 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.
