The video shows how to pre-assemble the multifunctional joint sealing tape ISO-BLOCO ONE CONTROL for plastic windows under controlled conditions already in the workshop. This is because the pre-compressed multifunctional joint sealing tape is equipped with a robust tear-open wrapping, which ensures the compression of the tape even after opening the roll. The expansion of the joint sealing tape is therefore only triggered after the windows have been installed, by removing the tear-open wrapping. It doesn't get any better than this. Fast installation and maximum control with the ISO-BLOCO ONE CONTROL multi-function joint sealing tape
