Vapour barrier sheet loft

Vapor barriers are sheets of plastic or other material placed on one side of insulation sheets. This barrier is meant to keep moisture from getting to the insulation in the walls and ceilings, and it is required by building codes when insulating most houses. In any case, the vapor barrier must point to the warm side. A vapor barrier is usually a sheet of plastic, commonly called “Visquene,” through which air and water cannot pass. A home that has a vapor barrier installed properly will be warm, dry, and will last a long time.

Thin plastic like this is often called a vapor retarder—meaning it slows the vapor down but doesn't stop it. A much better approach is a true vapor barrier, with characteristics that conform to the requirements of ASTM E-1745, "Standard Specification for Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs." Vapor barriers can be used in tandem with insulation in walls, in an attic, in a crawlspace or basement, under a concrete slab, over a concrete subfloor before installing wood or laminate flooring, or anywhere it's necessary to reduce the amount of water vapor that passes through.

Apr 24, 2014 · We can summarize the vapor barrier issue like this: A vapor barrier's job is to keep water vapor in humid air from diffusing through one side of a wall and finding a cool surface inside the wall. When a vapor barrier is on the side of a wall where the dry air is (i.e., outside in winter or inside in summer), moisture problems can occur.
