Illbruck TP651 Compriband Trio Tape

Illbruck TP651 Compriband Trio Tape 

Illbruck TP651 Compriband Trio Tape is an impregnated, pre-compressed sealing tape used to seal window and door perimeter joints against driving rain up to 600Pa, while providing airtightness, thermal insulation, and acoustic insulation in one product. An 'A' rated (WER) window fitted with TP651 can therefore be classed as having an 'A' rated installation.

TP651 Compriband Trio Tape — Keep Your A-Rated Windows A-Rated

Specifying an energy-efficient window only to install it with a basic seal defeats the purpose. TP651 uses a patented one-sided impregnation to control vapour diffusion in the right direction, protecting the window's rated performance rather than compromising it.

Product Overview

TP651 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, which also protects the tape against mould and fungi.
