Waterproof and airtight – where it matters

Moisture and drafts are silent problems in bathrooms and at windows: water seeps into gaps, cold air drifts through cracks, and over time damage occurs. A good door seal strip keeps water out and warmth in – and it should be easy to apply, without tools or expertise.

Material and Function

This door seal strip is made of silicone, a material that reliably keeps out water and air. The D-profile is a classic shape that fits into gaps and joints, forming a tight barrier. The self-adhesive backing lets you simply peel, press on, and you’re done – no glue, no tools needed. Silicone is durable, stays flexible, and does not rot, even when constantly wet.

The strip is sold by the metre, so you can buy exactly the length you need. There are different sizes – varying widths and heights – so you can find the right strip for your gap.
