I went to local glazing company for this product and told only place to get it was online. Not so! Local toolstation came up trumps again! Perfect for my upvc door gasket replacement.

Worked well, maybe install above 6C, but with a bit of faffing and brute force of strong fingers and thumbs, it went in and we now have a draft-free pair of patio doors.

Product was available in different lengths. We got the 20m tub. It was easy to fit and trim, and what a difference! The old seal was dry and cracked, but now we've replaced them with this, there's no more drafts through the windows. Easy and will save us money on our heating bill. Can feel the difference straight away and can't hear outside as much either. Fab!

Had to buy this as my father in law’s front door had let in a huge amount of water in the recent storms. It fitted perfectly and sorted out the leak. Easy to fit (woman, modest diyer) and well worth the money as there is loads left for any other leaky emergencies.

Great product

The rubber seal was easy to fit once the old seal was removed from the door surround. I used pointed tweezers for this.

Decent seal to replace some very old and some not-so-old seals in uPVC windows and doors.
Slot widths in windows do appears to vary - some windows were easy to fit and some very hard so check before the width before you buy, it isn't truly "universal".

I needed too replace the seals on bathroom window and front door, after removing the old seals and cleaning the areas the new seal fitted easily in place. The corners were a little harder to do but a little washing up liquid on the seal did the trick. I am very happy with the product.

So far so good
