When pushing into the grove, remember to push back towards the gasket before going around corners. This will stop the gasket shrinking due to being over stretched. Thank you. **Q: I have a disturbing whistle coming tbrough one of the upvc windows in my lounge when it's wi. Im no expert so does it sound like it needs a new seal?** A: I'm not a glacier or window fitter but this sealer did stop draughts on my older windows. Took out the old worn seals and replaced with this seal. It depends on whether it's the frames or where the window fits into the wall. The seal isn't expensive so you could try it if the wind still whistles after that then the seal isn't the problem. **Q: Is this the gasket which goes between the glass unit and the upvc frame ?** A: I believe what you are looking for is a 'wedge gasket'. Im looking for that too. **Q: Can you use on anglian bifold doors** A: Think it works on any pvc windows or doors. This was the 2nd one bought. The first was too thin and up till then didn't realise there was a difference so I would check measurement of what's on your doors before ordering. ## Frequently Bought Together - Stormguard UPVC Replacement Door and Window Gasket Rubber Seal (White) 25 Metres Double Glazing Seal - GB DIY Store 10 x Yale uPVC Universal Window Handle Inline Locking Espag Double Glazing White 40mm (Pack of 10) --- ## 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.tn/products/290783840-stormguard-upvc-replacement-door-and-window-gasket-rubber-seal-white](https://www.desertcart.tn/products/290783840-stormguard-upvc-replacement-door-and-window-gasket-rubber-seal-white) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-16*
