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.
