So, what is a moisture barrier? At its core, it is a shield designed to prevent moisture buildup in your home. Since only a small amount of moisture is required to create a suitable environment for mold and mildew, moisture barriers play a vital role in preventing the growth of these damaging organisms. This tool contributes to the longevity of your home and protects your health.

Different types of barriers exist, including the vapor barrier, which limits the flow of moisture and gas in your home, and the air barrier, which prevents air from passing through walls, floors, and ceilings. However, a moisture barrier is unique as it blocks all liquids, fortifying your home against moisture accumulation.

Do I Need a Moisture Barrier?

So, who needs a moisture barrier? If you’re embarking on a new construction project or remodeling parts of your home, you’ll need moisture barriers to protect vulnerable materials such as wood or drywall. Furthermore, a moisture barrier between the exterior wall and your home’s insulation becomes essential if you live in a hot, humid climate or an area prone to flooding.

But don’t be mistaken; moisture barriers aren’t just for warm climates. Even homes in colder regions can benefit from a moisture barrier. Installing a moisture barrier between the drywall and insulation is beneficial as warmer indoor air can hold more water, potentially leading to condensation and subsequent moisture problems.

Classifications of Moisture Barriers

There are three categories of moisture barriers based on their permeability:

  • Class I – These moisture barriers are the strongest because they are impermeable. Class I moisture barriers include glass, sheet metal, polyethylene sheets, and rubber.
  • Class II – These barriers are semi-permeable, allowing some moisture to pass through. Class II barriers include unfaced expanded or extruded polystyrene, 30-lb. asphalt-coated papers, plywood, and bitumen-coated kraft paper.
  • Class III – These barriers are the most permeable, allowing moisture to pass through. They include gypsum board, fiberglass insulation, board lumber, concrete block, brick, and 15-lb. asphalt-coated paper.

Most construction projects, including residential construction, will use Class I moisture barriers as they are the most impermeable of the three classes. Understanding these classifications can guide you in choosing a suitable moisture barrier.
