Review: Great product and an easy fit - Okay.... so I had noticed an increase in road noise and the cold seemed to be getting through. Checking the seals, something I hadn't thought to do since buying this house helped me to implement a quick fix. My.existing window seals where hard, brittle and the window thumped the frame when shut. It took me a couple of hours on a cold winters day to strip out existing seals, clean and replace. Thst fact these are lubed up really helps, and makes sliding into those tight fits so much easier. remember not to stretch and just be patient on corners. Would recommend and replacing the seals have helped windows are tight to frame and the lock levers are stiff as a result, drafts and noise have reduced.
Review: perfect - Fitted perfectly, easy to install.

## 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.
