What is DraughtEx?

DraughtEx is a proven floorboard gap filler which is designed to reduce cold draughts created by the gaps between your floorboards and improve the comfort and energy efficiency of your home.

The Energy Saving Trust estimate that filling floorboard gaps can save a household up to £40.00 per room per year on energy bills and reduce its CO2 contribution by around 110kg.

How Does it Fill Floorboard Gaps?

DraughtEx has been cleverly manufactured with thousands of tiny, concealed air pockets which allow it to be compressed by almost 90% of its original profile.

These flexible properties allow DraughtEx to be easily fitted into floorboard gaps much smaller than its original form by stretching it during the installation process. Once the floorboard filler is in the gap it will expand until it fills the entire width of the gap.

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. DraughtEx will mimic the movement pattern of the timber and therefore remain in place retaining insulation.

Great Results for Varying Gaps

Due to the nature of wooden floors and the way in which they are laid, the gaps between them often vary in size. To ensure that all gap sizes can be filled we offer DraughtEx in 3 different sizes.

    DraughtEx Thin has a profile of 4mm and is suitable for floorboard gaps less than 3mm in width - More Information.
  • DraughtEx Standard

    DraughtEx Standard has a profile of 8mm and is suitable for floorboard gaps between 2 and 7mm - More Information.
  • DraughtEx Thick

How to Fill Skirting Board Gaps

DraughtEx can also be used to seal the gaps between the skirting board and the floor. The size of these gaps often vary and traditional filling methods are usually time consuming, messy to install and will often fall out over time.
