Its wave profile ensures flexibility and durability across all weather conditions, providing superior protection against drafts, moisture, dust, insects, and noise. Easy to install with a self-adhesive backing and customizable length, it’s the perfect upgrade for energy efficiency and home comfort. ## Description The M-D Premium Silicone Rubber Window Seal for Ex-Large Gaps is designed to protect against drafts, moisture, dust and insects. Save on energy by sealing windows keeping the heat or air conditioning from escaping. Made of Premium Silicone Rubber this seal exhibits very high resistance to extreme temperatures and remains flexible when below freezing. It also provides maximum resistance to wear and tear. The self-adhesive design is easy to install by simply pressing onto a clean and dry surface. No hardware required. Before installation, cut to desired length using scissors. Review: This seal was easy to install and use and I saw that the draft coming through my windows immediately stopped. The only issue is that the adhesive could be improved, as the seal didn't stick well at certain points, but since I don't always open the windows, it's not a big issue for me. Review: For those occasions when good, ol' fashioned Duck Brand brown duct tape won't do the trick, this is an excellent, sturdy, and sticky product. It was recommended that I try using weatherseal around the frame of our door for soundproofing. We have had a serious noise problem, as our condo faces a loud common-area whose open space amplifies sound. Residents and foot-traffic generate noise that travels right into our unit. Since we were desperate for a modicum of peace & quiet, we thought we'd give this product a try. It was easy to apply around the door's frame; the silicone "wave" profile really does expand & contract to seal gaps. The brown color blends in unobtrusively. Now, there is a marked difference in the amount of noise-intrusion, for which I'm grateful. This M-D Building Products weatherseal provides an effective barrier not just to minimize dust and temperature variation, but against noise. Highly recommended! ## Features - Made of top-quality EPDM and silicone rubber tape - Seals gaps at the bottom of your window to protect against drafts, moisture, dust and insects - 3/8 in.

Highly recommended! ### ⭐⭐⭐⭐⭐ Review *by D***H on 21 April 2012* After buying two different types of weather stripping from the local Home Depot, we finally got this from Amazon. We used rubbing alcohol to prep the area so we got good adhesion when installing. It is an air-tight seal. The only 'downside' is that we have to pull pretty hard on the door to open it initially, if the door has been shut for a long time (I actually thought the door was locked the first time). --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/304149647-43846-all-climate-thermalblend-weatherseal-wave-profile-17-feet-white](https://www.desertcart.hr/products/304149647-43846-all-climate-thermalblend-weatherseal-wave-profile-17-feet-white) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-04*
