We are happy to provide suggestions. **Q: There is a picture of white - can you sell these in white?** A: Dear customer: Hello, there was white before, but now the white is out of stock, it will take a while to be in stock, I am very sorry! **Q: Does th7s stuff last? Doesn't look robust.** A: Not sure how robust a flexable window seal should be. It compresses as the window closes and works well. Only time will tell on it's longevity. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fits great and good value *by P***R on 26 January 2025* Very pleased with product ans seals window very nicely ### ⭐⭐⭐⭐ Good item *by N***L on 22 October 2023* The silicone is a nice change from the typical rubber used in such seals. As a whole the seal works as expected. ### ⭐⭐⭐⭐⭐ Great value seal and comes with useful tool to assist with installation *by S***M on 24 October 2022* I ordered this to replaced the door and window seals that needed to be a bit thicker as the UPVC doors and windows were had become bit out of true or misshapen over time.This was the thinkest I could find at short notice and has worked perfectly. Much cheaper than the DIY store stuff and also much thicker.It's quite easy to fit and I was pleasantly surprised at the tool provided to help push the strip into the UPVC channel. If you can find a point where you can push it in you could spray some silicon lubricant into the channel and pull it through otherwise you'll need to use the tool to ush the rubber in. --- ## 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.pt/products/242586390-cgc8-window-seals-upvc-replacement-door-and-window-gasket-silicone](https://www.desertcart.pt/products/242586390-cgc8-window-seals-upvc-replacement-door-and-window-gasket-silicone) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-16*
