Save up to Β£20 to Β£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 Β£20 to Β£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: Best tool for the job - 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. Review: Good product, pig to install - 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. ## Features - Proven floorboard gap filler designed to reduce cold draughts and save money. - Potential savings up to 40 GBP per room per year on energy bills and reduce CO2 contribution by around 110kg. - Standard, 8mm (on a 40m roll) to fill gaps of 3 - 7mm. - Also available in additional sizes to fill all gaps: thin for gaps less than 3mm, thick for gaps 10 to 12mm. - Flexible properties allow for easy fitting into floorboard gaps, requires no adhesive or specialist skill.

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. ### ⭐⭐⭐⭐ Good product, pig to install *by O***R on 8 December 2023* 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. ### ⭐⭐⭐⭐⭐ 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. ## Frequently Bought Together - DraughtEx (Standard) Floorboard Gap Filler for Home Insulation, Filling Gaps in Floorboards - DraughtEx - 4mm Width (40m Roll) - DraughtEx (Thin) Floorboard gap filler for home insulation, filling gaps in floorboards --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/52428259-standard-floorboard-gap-filler-for-home-insulation-filling-gaps-in](https://www.desertcart.tn/products/52428259-standard-floorboard-gap-filler-for-home-insulation-filling-gaps-in) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-22*
