## Description

DraughtEx - A quick and easy way to stop floorboard draughts and heat lossWhy Fill Floorboard Gaps? Save up to £20 to £40 per room per year on energy bills with added comfort. Gaps in between floorboards create cold draughts which lead to chilly rooms, discomfort during the winter months and increased heating bills. Floorboard gaps also allow insect infestation. Timber floors contract and expand throughout the course of their life. These variations cause alternative floorboard sealants such as papier-mache, wood filler and silicon to become ineffective and loose and eventually drop out. If you have experienced these problems, DraughtEx is the solution. DraughtEx will mimic the movement pattern of the timber and therefore remain in place. Thus retaining insulation, eliminating cold draughts and improving the comfort and energy efficiency of your home. Easy to install with the free applicator, DraughtEx requires no adhesives and compliments the overall finish of your floorboards. Its flexible properties allow DraughtEx to be applied to a wide range of gaps which will be completely sealed, and can also be used to seal gaps between floorboards and skirting boards. DraughtEx comes supplied with a free applicator and comes in 3 sizes: Thin for gaps of 3mm or less, standard for gaps of 3 - 7mm and thick for gaps of 8 - 12mm.Energy Savings A 12 x 12ft room has approximately 25 floorboards and an average gap area of 3.87 square feet which is similar to a small window being left open. Based on the results of research carried out by The Energy Saving Trust, it is estimated that filling floorboard gaps can save a household up to £20 to £40 per room per year on energy bills and reduce its CO2 contribution by around 110kg. Box contains one 40m roll of standard DraughtEx, Free Application Tool.

Review: Product excellent - 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 desertcart and desertcart blamed seller so if you want a refund it would be hassle. Had to talk to a customer service agent.
Review: Generally what I wanted - 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

### ⭐⭐⭐⭐⭐ Moth be gone ....
*by K***Y on 5 May 2024*

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.
