Finally, a door seal that stays put
You feel that cold draft every time you walk past the door.
You've tried the foam strips. They fell off.
You've tried the rubber seals. Too thick. The door wouldn't close.
Sealux is different. Its 1mm thick silicone is thin enough to let the door close smoothly—but strong enough to block cold air, dust, and even bugs. The industrial-strength adhesive grips in seconds and won't peel off, even in freezing temps.
No tools. No mess. Just peel, stick, and feel the difference the moment you close the door.

Frequently asked questions
Will this work if my gap is uneven?
Yes. The flexible silicone conforms to uneven gaps between 0-0.5 inches. It bends with your door frame without losing its seal.
Can I remove it later without damaging paint?
The adhesive is strong but can be removed with gentle pulling and a bit of rubbing alcohol. Some residue may remain on painted surfaces.
Does it work on glass shower doors?
Absolutely. Many customers use it to seal gaps in frameless shower doors to prevent water leaks.
Will it affect how my door opens and closes?
No. At 1mm thick, it's thin enough that your door will still close and open smoothly.
Does it work in freezing temperatures?
Yes. The silicone material and adhesive are designed to withstand extreme temps, from freezing winter cold to hot summer heat.
