DraughtEx Floorboard Draught Excluder Insulating Gap Filler (8mm Width - 40 Metre Roll)

DraughtEx floorboard gap filler 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 width by stretching and compressing it during the installation process. Once the floorboard filler has been inserted into the gap it will expand until it fills the entire width of the gap.

Timber floors naturally contract and expand throughout the course of their life because of changes in temperature and humidity. These movements create varying gap widths which can cause alternative floorboard sealants such as papier-mache, wood filler and silicon to become ineffective and loose and eventually drop out. DraughtEx is designed to expand and contract with the movement pattern of the timber and will therefore remain in place, retaining the insulation and preventing cold draughts.
