8mm Width - 40 Metre Roll

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.
