Vapor Barriers for South Dakota, Wyoming, and Nebraska

Waterproofing Your South Dakota Home

To keep moisture out of areas where it doesn’t belong, builders use vapor barriers. Understanding what water vapor barriers are can help you prevent moisture problems like dry rot and mold. Remember that humidity levels in your area are a big factor in the amount of moisture in the air within your walls. Families generate their own moisture as well. Examples of this would be cooking, house plants, showers, and even breathing. During winter months your home is heated to a higher temperature than the air outside. Air has a natural tendency to move from a warm area to a cold area, so the heated air in your home is always trying to move toward the ceiling, the floor, and the outside walls, carrying moisture vapor with it. Our homes also tend to be at a slightly higher air pressure than outside, and that overpressure is pushing the air and moisture toward the ceiling and the outside walls.

Vapor barriers are something that every home with musty, damp basements with wet walls or high humidity should look into having installed in their basement. Any material used for damp proofing, typically foil or plastic sheets, is referred to as a vapor barrier. These sheets resist diffusion of moisture through a wall, ceiling or floor. In technical terms, most of these materials are vapor retarders since the materials have varying degrees of permeability. We need moisture in our homes in order to survive, however, if it gets into the wrong places in our homes and is allowed to stay there, it can do a lot of damage.

For all of the above reasons, vapor barriers in most homes are necessary so that moisture cannot pass through to cause moisture problems to the structure. Plastic sheeting is an example of a barrier that moisture would not be able to permeate. Warm air in your home is trying to escape through the exterior walls, carrying moisture vapor with it. If it gets into the exterior walls some of it will stay in the walls and condense back into a liquid, a situation that can lead to big problems. One of your home’s most common vapor barriers is one of the most important. It’s the plastic sheeting used over the insulation in your exterior walls. It is designed to stop the moisture before it can enter the wall cavities.¬†Call Rapid Foundation Repair for vapor barriers in South Dakota, Nebraska, and Wyoming.
