fowong Adhesive Weather Stripping 12mm(W) x 12mm(T) x 2M(L) Home Window Insulation Self Adhesive Foam Tape Seal Soundproof Shockproof Gap Sealing, 2 Pcs Total 4M Long

I have used this on the sash windows and wasn’t expecting these to work that well. Theses have worked a treat. Absolutely no draft and have used on all the windows. I wish I had these years ago. Although our place gets cold in the winter without the heating, it is not as much as it use to be. Thoroughly recommend this product.

The foam is very stiff. It is 5mm deep. When pressed as hard as you can between thumb and finger it reduces by half. So if the gaps you want to seal vary by more than 2.5mm - eg in a warped door - this will be no good for you. Look for alternatives described as "soft" foam.

Really good quality, sponge rubber-type material which is dense but has spring to it. I ordered the 10mm x 10mm rolls as the gap in the door was significant however it was too deep so I trimmed it down to 5-6mm with a standard pair of scissors and it now fits a treat. Easy to apply, the stickiness is good. Seems like it will last and so much better than the sealer which it replaced. Door now fits better too and no more drafts. Highly recommended.

I bought it- it arrived very quick.So me with full happiness run home to use it and finally keep my doors from cold gaps!After putting it all over the doors- Guess what? It just fell down again. The glue was dry , so it could not be attached to any surface .Will never get it again

Good value and quality

As advertised, thick, firmish foam. Not very adhesive, so better get placement right first time. Also, 4m doesn't go far and is not enough to do a door frame. Seems pricey for what you get. Package arrived open/unsealed. The item was in there, but no paperwork.

Easy to apply, but a bit fiddly to get the tape off the sticky side. Has stopped the draught so very happy, as are my plants

I have to say this product is amazing. I brought it due to our sliding pots I the utility area was letting lots of cold area which came through to the house and for a window upstiars. The difference is amazing, both areas feel alot more warm and we do not need the heating on as much to stay warm. I will be buying more of this for some place I yet to work out but for someone who never writes reviews and spends alot of money on amazon. This product is the first which truly deserved a review as the difference was immense.
