Stormguard Rubber Foam Jumbo Weatherstrip 3.05m – Self-Adhesive Draught Excluder
Extra-thick self-adhesive foam weatherstrip that seals gaps up to 11mm, blocking draughts, water and dust while helping cut your heating bills.
Stormguard Rubber Foam Jumbo Weatherstrip is built for the larger, more stubborn gaps that standard draught strips can't handle. If cold air is creeping in around an ill-fitting door, window, loft hatch or roof box, this jumbo seal closes gaps between 3mm and 11mm with ease. It's self-adhesive, trims to size with scissors or a craft knife, and fits in minutes without tools or specialist skills.
Manufactured from durable rubber foam, this weatherstrip is designed to withstand repeated compression without losing its shape, so it keeps sealing effectively long after cheaper foam strips have flattened out. Available in Black or White to suit your frames and fixtures.
Key Benefits for uPVC Door and Window Owners:
- Seals Gaps Up to 11mm – Perfect for larger, uneven gaps where standard draught strips fail to make contact, stopping cold air and water getting through where it matters most.
- Cuts Heating Bills – A properly sealed door or window keeps warmth in and draughts out, so your heating doesn't have to work as hard through the colder months.
- Self-Adhesive, No Tools Needed – Peel, stick and trim to length in minutes, giving you a professional-feeling result without calling out a tradesperson.
- Extra Wide and Extra Thick – At 19mm wide and 11mm thick, this jumbo profile handles gaps that thinner strips simply can't bridge.
- Superior Shock Absorbing with Minimum Compression – Cushions doors and windows on closing while holding its shape, so the seal keeps performing instead of crushing flat.
- Extra Tough and Durable – Built to withstand daily use and UK weather, so you're not replacing the seal every season.
- Trimmable to Any Size – Cut it down to fit your exact frame length, with no waste and no need to order multiple sizes.
- Genuinely Multi-Purpose – Beyond doors and windows, it's just as useful on boats, loft hatches, roof boxes and automotive panels, so one roll covers several jobs around the home.

Pro Tips:
Pro Tip: Clean and dry the surface thoroughly before fitting – any dust, grease or moisture on the frame will stop the self-adhesive backing bonding properly and shorten the life of the seal. For best results, fit in mild weather above 5°C, as the adhesive bonds more reliably in warmer conditions.

Frequently Asked Questions:
Will this weatherstrip fit the gap around my door or window?
It's designed for gaps between 3mm and 11mm. Measure the largest part of your gap before ordering – if your gap is smaller than 3mm, a thinner Stormguard seal would give a better fit.
Is it difficult to install, and do I need any tools?
No specialist tools are needed. Clean the surface, peel back the adhesive backing, press the strip into place and trim any excess with scissors or a craft knife. Most doors or windows take just a few minutes per side.
What colour options are available?
This weatherstrip is available in Black or White, so you can pick the option that best matches your existing frames or fixtures.
How long will the seal last before it needs replacing?
The rubber foam construction is built for minimum compression, meaning it resists flattening far better than standard foam strips, giving you a long-lasting seal against draughts and water ingress.
Can I use this outside of windows and doors?
Yes. It's also popular for sealing boats, loft hatches, roof boxes and automotive panels wherever a durable, self-adhesive foam seal is needed.
