## Description

Bantie 20FT Weather Stripping Door Seal, Self-Adhesive Silicone D-Shaped Seal Strip for Door Frame & Window Gaps, Soundproof Insulation Gap Filler - desertcart.com

Review: Good deal and keeps out the drafts - The weather stripping works very well at sealing the gap at the top of my entrance door. I had never noticed that it was missing until I saw light shining thru the top of the door. I did have to double layer it as my measurements were off and I ordered the wrong size. But it seals well and I don’t have any light coming thru. Installation is a breeze and it stays put once applied. I do have to double layer a positive door lock check, because it doesn’t close unless I give it a little extra push. But that’s not a deal breaker.its a good deal.
Review: Great way to save a little money on energy bills. - Just as described. The seal is amazing, the quality of the silicone feels good, 3M adhesives are generally best in the business and this is no different. Was very easy to install, they even provide gloves and alcohol wipes to clean the surface and help stick even better. It is silicone, so it is more flexible and less rigid than foam alternatives and can be a bit harder to keep in a straight line. Overall the value this will add in less heating and cooling will easily pay itself off in a single season.

### ⭐⭐⭐⭐ Disappointed
*by H***Y on August 12, 2026*

Used this on my camper windows. We wished the adhesive had been a little better. We also thought we were still seeing daylight but it turned out we were seeing through the clear adhesive. I don't love that part.
