Sealing Tape: Self-Adhesive and Foam
Sealing tape removes draughts, noise and heat loss where two surfaces meet but never sit perfectly tight.
Self-adhesive sealing tape goes on in one pass, without tools — peel the backing and press. Foam sealing tape (closed-cell polyethylene or XLPE) is elastic and compressible, so it fills irregularities and keeps sealing even when the gap varies along its length.
Door sealing tape is the most common household use: applied to the door frame or leaf, it stops draughts, reduces noise from the stairwell and improves insulation without replacing the door. In construction, sealing tapes are also used under skirting boards, between structural joints and as an acoustic layer between metal profiles and load-bearing walls.

Frequently Asked Questions
What's the main function of XLPE tape?
XLPE sound insulation tape is mainly used for noise dampening — it wraps around sewage pipes and sits between structures and walls to reduce vibration and sound transfer.
How do I choose a sealing tape for joints and connections?
It depends on the location — for moisture-prone areas (bathrooms, basements), a butyl fleece tape is the right choice; for noise reduction, XLPE tape works best. Both give long-lasting protection when applied to a clean surface.
Do sealing tapes replace traditional sealants?
Yes, and they're often more effective — unlike sealants, which crack and lose flexibility over time, tapes stay flexible for their full service life and don't shrink.
