4mm Width (40m Roll)

Last year we bought and moved into a 1900/1910 house, where the previous owners had removed the hall carpet and stained the original floorboards. Looks beautiful. One small issue: wherever the floorboards have been taken up to allow electrical or heating work to take place in the crawl space, there are gaps between boards and cold air flowing up unchecked.Various other solutions would fill the void but ruin the aesthetic of the floorboards (ie look like LVT, or laminate).With this, using the provided wheel, or in some sections: a fingernail to press into place, the look of the floorboards remains and the draughts are stopped. Definitely recommend if facing similar problems.Little bit fiddly at times depending on the size of the gaps, but worth the perseverance.

I got this a while ago but it didn't suit what I got it for. I tried to squeeze it beneath my laminate beading, because I could feel a draught coming from all the way around my floor. It didn't really seem to do anything so I just put it in my garage. Recently I decided the draught from my floor (laminate) was too much, and I couldn't bear another cold winder where my heating was just wasted. I ripped up my laminate flooring in order to put a good underlay and carpet down. When I'd ripped up the laminate, I remembered this product, so thought I may as well make use of it. Firstly, it is very tricky to get the hang of. My method ended up being using a 1p coin to lodge the start point of the draught excluder. I then gently rolled the provided tool across the gap in the floor boards, whilst with my other hand holding the excluder string and stretching it out whenever the gap became smaller. Sure enough, using this method allowed me to install the excluder inbetween the boards. It takes time, patience and strong knees (ended up buying some knee pads after an hour or so). Amazingly, the draughts did disapear. I completed half of the flooring and then ran out of product. Because of the difference in the completed half, compared to the uncompleted half, I even got another roll to finish the room.It lost one star because with about 8m of product left, the tool used to install it just broke to pieces. It's really good to use for installing it,, but its not built to last.All in all, I'd recomend it, especially if you live in an older house with a suspended timber floor, like I do. Eventually I want to use this stuff on the whole ground floor of my property, but I'll do it as and when I can be bothered to change the flooring. You will be amazed at how much cold air is brought into the home from underneath the flooring.

I've used the 4mm and also bought an 8mm it to fill gaps (of varying thicknesses) between floorboards before they will be sanded. I bought this both for the thermal benefit and also to help the sawdust & filler (which will go down with the sanding) not to fall down between the boards over time.I found this a little tricky to install at first but soon developed a couple of techniques, including smoothing the gaps a bit with a knife first (nothing too exhaustive, just to shift stuck tiny stones that might stop this from going in) and then stretching the filler smoothly & squashing it about as it goes in, where the gaps are thinner or varying widths. I think stretching it the right tension for the right width is the key to fitting it, which is easier than it sounds once you've done a plank or two. All gaps in the photo above are filled.It does work out quite pricey for a large area but I really rate this stuff and have already bought more for another room.

Everything was easy to use and instal, my only suggestion would be to not push so hard when using the roller

I wedged this in between floor board gaps then applied wood filler on top. I then sanded down the floor and applied varnish. I did it like this as wanted it to look kind of rustic and not too perfect! You can just wedge it in between gaps and not use filler but I only had a few gaps so wanted the whole thing to blend in. Very happy with final result! Love the little device that comes with it helps you get a tight fit without snapping the draughtex foam

I was a bit doubtful about this product, but honestly, it was much better than I expected! Very easy to install and learn, and immediately improves the look of the room, making it much more finished and clean, besides reducing significantly the the annoying dust between the gaps and the squeaky floorboards. I wish I had bought it sooner, and I’m sad to see that the 8mm is currently sold out, as some of my gaps were bigger, so I also recommend checking the right size of the floor gaps. I’m very happy I found this and just can’t recommend it enough!

Fantastic product - these rubber strips have helped the drafts fromthe cellar and I can no longer smell the sheep’s wool insulation under the floor.Easy to use (so my husband says)5 Star
