Vapor Barrier Shower Walls Tile

Water vapor that gets behind walls or travels up through light fixtures or hvac grilles into an attic will turn back into water when it cools off.

Vapor barrier shower walls tile.

Use appropriate tape to adhere two pieces of vapor barrier and edges to avoid moisture entry to the back walls. A vapor or moisture barrier is a layer of protection that is designed to act as a waterproof shield helping to keep condensation away from wood insulation and other mold prone materials that are located behind the drywall. In a shower situation you recognize it as steam. Before tile can be installed on shower walls a moisture barrier must be secured so that any water that penetrates through the tile and grout does not get all the way through to the wooden wall.

Water vapor is water in a gas form. Run the height of the vapor barrier from the top all the way down into the shower pan make sure not cut too short before the water barrier. Steam stays in a gas form until it cools down or hits a barrier such as a shower door tile ceiling or a mirror. It s usually a thin layer of plastic that sits between the drywall and the studs.
