Review: Wish I’d done this years ago - excellent product. - Our conservatory is over 20 years old and the original door gasket seals had perished. They were brittle and hard, so sitting near the door in the winter meant you could feel a definite draught. Over the years I had tried to fix the problem with those stick on strips you can buy from DIY stores but they looked messy and were never man enough for the job. I had a glazing firm in who said that the original ones were no longer made - usual story - so I thought I take a chance and order online. I did some research and because they were in a state, I measured a bit of the old gasket as accurately as I could. This universal seal is perfect! So easy to fit, I was getting suspicious! The arrow head part just popped into the groove with a little bit of pressure, I got away without needed washing up liquid, but a great tip. As others have mentioned, there does seem to be a little bit of lubricant on already which definitely helped. I found that it pays to be a bit careful to keep checking that when you are pushing the seal in, to go back and check that where you first started hasn’t slid along, especially before you cut of the excess at the end. If it has moved, it’s easy just to push it back into place with a bit of thumb pressure. The worst part of the whole job was pulling and digging out the original seal from the grooves, especially at the base. I’m so pleased with the final result. As well as being more efficient, the door looks clean and brand new - better than it has for years. I don’t know why I didn’t do this ages ago.
Review: Works for me!! - Bought this after reading reviews. Fits my standard upvc door. Was a little concerned when parts kept popping out but that could've been me as after more pressure it's all in one place and appears to have stayed. Cant complain with the amount you get for the price. 20m! Have plenty to replace most of the windows if needed

## Questions & Answers

**Q: Is there a tool that helps with pushing the seal into place? It's really hard to get it pushed into place on my windows and feel that I could do with**
A: There's no tool to help. Make sure the window runner is clean then to make it easier use a cloth with some washing up liquid on, wipe the runner 1st with it and this should help it slide on easier.

**Q: Does this product fit all double glazed windoes and doors ?**
A: We cannot guarantee it fits ALL as there are so many different types/styles/sizes but it is a universal seal and fits most upvc frames.

**Q: can this be used externally around the glass between glass and upvc frame? The original wedge gasket has shrunk and water is coming in window.**
A: I don't think so. I used it for frame round upvc door which was perfect.

**Q: How well does this block sound from entering and escaping the room (of an internal door)? Does this create a 100% airtight seal aswell? Thanks**
A: This rubber seal is a replacement seal for upvc door and windows. I would not use it on any other type of door and would struggle to believe that you have upvc internal doors in your house. I think that foam strip would be better solution for internal doors. No matter what seal you fit the door must apply gentle pressure on it without any gaps to ensure good seal.

### ⭐⭐⭐⭐⭐ Good quality
*by J***S on 16 March 2024*

Good quality and easy to install. Use a little soapy water to aid with install. With this I was able to replace the seals on one side of my Upvc door frame and also do 2 seals on a 4 x 4 meter window frame (6meters) and one seal on another 4 x 4 meter window frame (12 meters in total). Just enough left over for our small bathroom window (2 meters). Will happily buy another one for the rest.
