Floor Tiles With Vapor Barrier Mechanism

  • Floor tiles with a vapor barrier such as Sheet Polyethene (0.1 perms) create a barrier between floor tiles and the finished area.
  • It will let moisture airflow under your floor tiles. Thereby trapping of vapor below floor tiles gets prevented.
  • By creating a gap between your floor tiles and concrete. And it will form a moisture barrier under the tile.
  • Thus we get the effective moisture displacement hence no more creation of dampness and mildness.
  • In short, water vapor passes through and is now building up under the tiles.  Floor Tiles with vapor barrier creates a vapor barrier between the concrete basement floor and finished basement area, having space for the air to move under the floor tiles and for moisture to dry.
