8100 is a weather-retardant, impregnated, open-cell, polyurethane soft foam, enclosed before use in a polypropylene film with a bonding adhesive on one side for fixing.


Our 8100 is an impregnated, pre-compressed foam sealing tape, encapsulated before use in a tear-off, polypropylene film with a bonding adhesive on one side for installation. The tape is intended for the external, recessed perimeter sealing of windows and doors with the same high performance characteristics as 8000. The tear-off, encapsulating film permits the post-installation expansion of the foam strip, thus ensuring an effective weather seal.

In order that driving rain resistance is maintained to a minimum of 600 Pa, it is essential that the maximum recommended joint width is not exceeded. To ensure that irregularities can be sealed by the tape, aperture surfaces must not be excessively rough. The information provided herein represents general guidance only. The user is advised to conduct trials to establish suitability for his particular application.
