10 Best Condensation Strips for Windows
1. Silicone Seal Door Strip Bottom – 8M/26ft (W: 35MM)
Best for: Homeowners who want a low-cost way to reduce condensation on windows and doors.
The Beicarin silicone door strip is a simple but effective fix if you’re dealing with condensation around window and door frames. By sealing the small gaps that let in cold air, it keeps the glass surface warmer and less prone to fogging. That means less water build-up, fewer mould patches, and a more comfortable room overall.
The roll comes in a generous 8 metres, so you can cover several doors and windows, and it’s clear, so it blends in with frames without spoiling the look. As a bonus, it also cuts down on draughts, noise, and even insects sneaking through gaps.
Key Features
- 8M (26ft) roll, cut-to-size for multiple frames
- 35MM width with strong adhesive backing
- Helps reduce condensation by limiting cold air gaps
- Clear silicone for discreet fitting
- Also blocks draughts, insects, and noise
Pros
- Targets condensation at the source—gaps and draughts
- Long roll suitable for several installations
- Clear finish blends into most frames
- Works on windows, doors, and shower screens
Cons
- Adhesion can weaken if surfaces aren’t cleaned first

Condensation Strips Buying Guide
When choosing a condensation strip for your windows or doors, it helps to focus on a few key factors. Here’s what to consider:
1. Type of Condensation Issue
- Water forming on sills: Choose absorbent strips like FuKuEn, ZKFSIE, or Oniissy that soak up excess moisture directly.
- Cold air gaps causing fogging: Opt for draught excluders such as Bynsaer, Esufeir, UPSEN, or Fowong, which seal the airflow that leads to condensation.
2. Gap Size
- Small gaps (≤3mm): Use thin foam tapes like UPSEN.
- Medium gaps (3–6mm): GUKOY Type D is ideal.
- Large or irregular gaps: Wedge-shaped strips like Esufeir or thicker foam tapes like Fowong provide a better seal.
3. Material & Absorption
- Felt or non-woven fabric is best for moisture absorption (FuKuEn, ZKFSIE, Oniissy).
- EPDM or PU foam is durable and compressible for sealing gaps (Bynsaer, GUKOY, Esufeir).
4. Length & Coverage
- Longer strips allow coverage of multiple windows or doors. Some products provide multiple rolls per pack (Gsrhzd, Oniissy), which is handy for larger homes.
5. Adhesion & Ease of Installation
- Strong adhesive ensures long-term use. Clean and dry surfaces before applying to maximise stickiness.
- Reusable absorption strips are handy for seasonal condensation without constantly re-purchasing.
6. Additional Benefits
- Some strips also offer noise reduction, dustproofing, impact cushioning, or energy efficiency. Decide if you want a multi-purpose solution or just moisture control.
💡 Pro Tip
Combining strategies can work best — use an absorbent strip for existing condensation and a draught excluder for gaps causing fogging. This dual approach keeps sills dry and glass clear all season.
Answering Common Questions on Condensation Strips for Windows
-
Do condensation strips work?
Yes. Condensation strips absorb moisture or block cold air entering through gaps, keeping window sills dry and reducing mould, damp, and water stains.
-
How do condensation strips work?
They work in two ways: moisture-absorbing strips soak up water running down glass, while foam or rubber strips seal gaps to prevent cold air, which causes condensation, from reaching windows.
-
Can condensation strips be reused?
Many moisture-absorbing strips, like ZKFSIE or Oniissy, are reusable. They absorb water, allow it to evaporate naturally, and continue protecting your windows throughout the season.
-
Where should I place condensation strips on windows?
Place them directly on the sill or along the bottom edge of the glass where condensation collects. Foam strips are best in gaps between the window frame and sash or door.
-
Are condensation strips suitable for all window types?
Yes, most strips work on wood, metal, or uPVC frames. For boat windows, glass doors, or air conditioners, reusable adhesive moisture-absorbing strips are ideal.
-
How long do condensation strips last?
Foam or rubber sealing strips can last multiple years if applied correctly. Absorbing strips last a single season, but most are designed for reuse within that period.
-
Can condensation strips help with draughts and energy bills?
Absolutely. While primarily for moisture control, sealing strips also reduce cold air drafts, improving warmth in winter and potentially lowering heating costs.
