## Description

Seal gaps in floorboards with this flexible, easy-to-apply filler. Helps improve home insulation and reduce drafts, maintaining comfortable indoor temperatures.

Review: Easy to use, effective product that arrived promptly - I used this to seal the gaps between the floorboards before my new underlay and carpet were fitted. I was advised by the carpet fitter to block the gaps to prevent dust and dirt coming through onto the carpet. The product was very easy to use either with the help of the wheely thing supplied or the edge of an old membership card. Very quick and easy to install and the one reel dealt with all the gaps in my modest sized room. I took the view that if this thin draught excluder wouldn't fit in the gap the then gap was small enough not to be a probelm or to provide minimum dust ventilation.
Review: Floor draught - Excellent

## Questions & Answers

**Q: Will this be fine to pad out loose floorboards.**
A: Thank you for your question. The DraughtEx is very versatile and flexible, but is specifically designed to bridge gaps and prevent draughts between floorboards. We can therefore not guarantee it would be suitable for padding out loose floorboards. The gap between the floorboards needs to be at least a couple of millimeters deeper than the diameter of your roll. Additionally, the diameter of DraughtEx lays between 4-12mm depending on the version you buy so please ensure the dimensions are correct for your application.

**Q: What is the filler made from? Is the filler fire retardant, or at least compliant with fire proofing regulations/standards?**
A: The Draughtex is a closed cellular Black EPDM Sponge Rubber Cord that can expand in a gap and provide protection against cold draughts and improve energy efficiency. The manufacturers do outline that the flammability resistance is low on this material, though, but is very resistant to cold temperatures and conduction of electricity.

**Q: Does this thin roll of Draughtex include the plastic applicator?**
A: I think it did, I ordered several different sizes from different sellers but definitely got more than one applicator. Some gaps were too thin for the applicator so had to use a blunt knife or credit card, which work just as well. Very happy with product

**Q: How to order the standard size for gap 3 to 7mm**
A: Its thin and rubbery but great to fill in gaps to stop draughts and damp  hope this helps @

### ⭐⭐⭐⭐⭐ Easy to use with no mess!
*by H***2 on 9 December 2025*

Easy to use and effective. I have previously used a floor filler which was very messy and cracked over time. This product was quick, effective and I can already feel the difference. For some of the smaller gaps I used the edge of the craft knife to ensure they were pushed down. Def would recommended.
