Review: Excellent draught proofing and noise control - Our window seals were 15 + years old and had began to split so replacement was long overdue, We ordered a few tubs of Stormguard as this brand was recommended to me by a friend. It was super easy to fit and has made a huge difference. Our house definitely feels much warmer already but the big difference is the sound proofing - we live near a busy town centre and the noise has been reduced significantly which is a major plus for me as I work nights. Money well spent - highly recommend.. Review: Good product, easy enough to fit it yourself but do measure first - Having noticed a draft coming from the window, I found online that the seal might be the problem and looked at how to replace it (there are some good videos to show you how, just do a search). I actually removed the window and brought it inside, which made it easy to remove the old seal and put in the new one. It would’ve been very fiddly to do it around the hinges otherwise. I would consider myself to be a competent amateur DIY’er, and I managed fine to both remove the window and to put in this new seal. I did measure the gaps as recommended by other reviews, to make sure I had the correct seal, and it popped in just fine. Just take your time to go round and press it in, sometimes needs an extra press after so a second check round the edges is worth it. So far no draft, so I think it’s a job well done. Very pleased with it. ## Features - Important - Before ordering, please check sizes shown on the diagram match the gasket you are replacing - Fits window frame grooves between 3.2mm to 4mm wide - Pushes into existing groove on the frame of double glazing window seals - Seals gaps 3mm to 4.5mm (gap between frame to sash when closed) of double glazing seal - Bubble gasket weather seals opening sash to frame when closing, window seals for double glazing - Upvc window seal not suitable for sealing between frame and glass ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08XJSR4C1 | | Batteries Required? | No | | Best Sellers Rank | 7,233 in DIY & Tools ( See Top 100 in DIY & Tools ) 39 in Draught Excluders & Seals | | Colour | White | | Customer Reviews | 4.5 4.5 out of 5 stars (5,811) | | Date First Available | 25 Feb. 2021 | | Guaranteed software updates until | unknown | | Installation method | Push in | | Item Weight | 770 g | | Item model number | 21CP397025MW | | Manufacturer | STORMGUARD | | Material | Rubber | | Part Number | 21CP397025MW | | Product Dimensions | 2500 x 0.8 x 0.9 cm; 770 g | | Shape | Oval | | Thickness | 0.8 Millimetres | ## Images ![UPVC Replacement Door and Window Gasket Rubber Seal (White) 25 Metres Double Glazing Seal - Image 1](https://m.media-amazon.com/images/I/71SJ4i2hKBL.jpg) ![UPVC Replacement Door and Window Gasket Rubber Seal (White) 25 Metres Double Glazing Seal - Image 2](https://m.media-amazon.com/images/I/51etVF6++pL.jpg) ![UPVC Replacement Door and Window Gasket Rubber Seal (White) 25 Metres Double Glazing Seal - Image 3](https://m.media-amazon.com/images/I/61UYOfc6pKL.jpg) ![UPVC Replacement Door and Window Gasket Rubber Seal (White) 25 Metres Double Glazing Seal - Image 4](https://m.media-amazon.com/images/I/61Y2yvc319L.jpg) ## Available Options This product comes in different **Colour Name** options. ## Questions & Answers **Q: Any tips on how to make the corners fit better** A: You can cut a small 'V' notch in the corner (not all the way through the gasket), however its easier to work the gasket around the corners without cutting. 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent draught proofing and noise control *by N***M on 2 January 2025* Our window seals were 15 + years old and had began to split so replacement was long overdue, We ordered a few tubs of Stormguard as this brand was recommended to me by a friend.
