(Standard) Floorboard Gap Filler for Home Insulation, Filling Gaps in Floorboards

Fantastic, exactly what I needed and couldn't have done the job better. Covered a large room with plenty to spare, fitting an impressive range of wide and thin gaps. Easy to install, made a big job very simple.

I am sure this will do the job of reducing draughts and energy waste but it can be a pig to install. The video of a young lady doing so with ease is only true with a perfect gap, anything less and it is a real struggle with the supplied wheel being quite useless.

We suffered from an increasing population of clothes moths which seemed to be thriving in 50 years worth af accumulated dust beneath our uncarpeted floor boards in our bedroom. After two days of painful and very dirty head under floor boards hoovering (which wasn't mentioned in the Husband job description i successfully applied for over 20 years ago) I wanted to prevent new dust falling through the gaps dust and re accumulating. I bought two rolls of this stuff (4mm and 8mm versions). It's hard work actually, and you'll need a cushion for your knees, but the pizza cutter roller thingy that come with it is heavy duty and really helps. Metre for metre the 8mm goes much further as you tend to stretch it to fill increasingly thinner gaps. The 4mm version will snap if you stretch it too much...but you don't need to as it squishes into all but the tightest of gaps. If you have uncarpeted floors you'll need to roller it down to the full depth of the pizza wheel shoulder and poke the ends down with a flat headed screwdriver so that it isn't dragged out by the hoover. All in all really pleased. It's been a long job all in all but hopefully that's the end of the moths.

Product is excellent. Delivery was terrible thanks to Evri. It went to an industrial unit and we had to go and collect it. Seller blamed Amazon and Amazon blamed seller so if you want a refund it would be hassle. Had to talk to a customer service agent.

Product is really good and makes a huge difference stopping any draught. Tricky to get started but once going the applicator tool makes light work.. until the tool breaks. Friction on the pivot part caused the plastic to heat up and melt/fail.

Installed recently, but so far has not come out of the wider gaps between floorboards. Floorboards move and another product I've used occasionally comes out when the floor is walked on, so the squishiness of the DraughtEx is helpful there. Generally looks like dark shadows between the boards, quite smart. Installation really easy. The gaps under the skirting boards were a bit tight sometimes, so I ended up using a combination of a phillips screwdriver to hold one end in place and an old credit card equivalent or the plastic pizza wheel provided to install it. It also stretches to do slightly thinner gaps, which is helpful in avoiding chopping and changing between sizes and means you use less. I needed one and a half reels to do two rooms and a hallway, plus a reel of the next size up (approximately 34m2). So far, so good - floors definitely less draughty. Given the holes around our radiators and old knotholes in floorboards, am not worried about damp or air ciculation but considering if you're looking at getting airtight in an old house. The draughts coming from the remaining gaps are noticable, so it is having an impact. Would recommend and use again.

It goes in quite easy and the 40m will go alot farther then you might think. It is to be used between 3-8mm gaps so if most of your gaps are 4-5mm for example it'll go 2-3 times as far. If gaps are 3mm or less, try and find the thinner stuff. I'd recommend having some on hand since surely you'll have smaller gaps then you think in some places. The provided tool is perfect for the bulk of the work, though doesn't work for the ends. The ends are really more of an art to get in properly, but that's how these tasks can be no floorboard set is the same so all come with their own set of simplicity and challenges Generally what I was looking for in the end

The perfect solution for stopping draughts between skirting and wooden floor in a new extension. I had a significant draught coming through the gap due to a suspended floor being installed. This product basically stopped it entirely. The gap isn't even consistent; it varies from around 2mm to around 5mm, yet the product covers easily between the sizes since it's easily compressible. It was pretty easy to apply with the provided tool on the larger gaps, although I had to use a spatula / screwdriver in a couple of tight spots since the tool doesn't work with the smaller gaps. If I could make one suggestion it would be to include a second tool for the small gaps since my metal tools did scrape a little of the product away when pushing in. But overall, an excellent product.
