Moisture is a Serious Concern in Any Building

Whether you are building homes, office buildings, or commercial structures, moisture should be at the top of your list of concerns. Moisture in the building envelope is a problem in any kind of structure, because it can lead to problems such as:

  • Mold and mildew buildup which can lead to allergic reactions
  • Harboring of insects and rodents
  • Cracks and breakage due to freezing and thawing
  • Corrosion and rotting of building materials

There are three common contributing factors to moisture buildup in the building envelope. These are water leaks, vapor diffusion, and air leaks. Leaks around window frames and drainage pipes and outside air entering the wall due to poorly designed air barriers are often to blame.

Luckily, there is a great way to fight against moisture buildup in building envelopes. By addressing water leaks, vapor diffusion, and air leaks, spray foam insulation does far more than insulate -- it protects your building from moisture damage. Here's a look at just a few ways that spray foam insulation accomplishes this task:

  • Spray foam insulation prevents heat transmission, so dew point conditions are not met and water vapor does not condense within your structure.
  • Spray foam insulation provides an air barrier, so moist air is kept out of your building envelope.
  • Using spray foam materials for your construction projects provides you with a moisture-tolerant insulation. Unlike fiberglass, it cannot absorb moisture, so it does not become a home to insects and other pests.
  • Water does not travel through closed-cell insulation, and its structure will not be ruined if it does happen to get wet.

When it comes time to find the best materials for your construction projects, you can rely on NCFI Polyurethanes. Contact us to learn more about our spray foam products, including commercial and residential spray foam insulation, roof coatings, and more.
