Alenor butyl fleece waterproofing tape

Alenor butyl fleece waterproofing tape is a thin, flexible butyl tape with a polypropylene fleece (non-woven) surface. Use it to seal cracks, seams and joints where water or moisture leaks must be prevented: wall-to-floor joints, pipe penetrations, window and door edges. The tape contains no bitumen, so it can also be used in living spaces.

The butyl rubber layer has permanent tack, while the fleece reinforcement makes the tape stronger and more flexible. If the tape is punctured or cut, the butyl seals the hole by itself. The adhesive side is covered with a split release liner, so the tape is easy to apply in corners and hard-to-reach places.

Frequently asked questions

Can this waterproofing tape be used indoors?
Yes. The tape contains no bitumen, so it is approved for use in living spaces.

How is fleece tape different from aluminium butyl tape?
Aluminium butyl tape has a foil surface, fleece tape has a non-woven fabric surface. Fleece tape is thin and flexible, so it adapts well to corners, pipes and uneven surfaces.

Which width should I choose?
100 mm suits narrow seams and pipe penetrations, 150 mm suits wall-to-floor joints and wider cracks.
