G-Flex Timber Floor Reinforcing Sheet


A reinforcement sheet to allow tiling over timber floors and helps prevent:

  • Cracking tiles.
  • Loosening tiles.
  • Rotten timber.
  • Grout staining.

Unlike plywood, Genesis G-Flex is simple to cut and install, a knife can be used to cut the sheet and is fixed using the self-adhesive backing. Offers quicker installation time compared to using plywood.

Can be used when incorporating electrical under-tile heating systems and in conjunction with Genesis Waterproofing system.
