What is spray foam insulation for crawl spaces?
Spray foam insulation is a highly effective type of insulation that is well-suited for various applications, including crawl spaces. Spray foam insulation is a two-part system that is made up of polyurethane foam and a chemical curing agent. When these two components are combined, they react chemically and create a foam that quickly expands and hardens. The resulting foam is incredibly dense and effective at blocking air leaks, stopping water vapor from entering crawl spaces and providing excellent insulation.
When applied to a crawl space, spray foam insulation can create a sealed barrier that helps to keep the temperature inside more constant, preventing heat from escaping during the winter months and preventing the hot and humid air from entering during the summer months. The foam also stops air leaks in the crawl space walls, which are typically a major source of heat loss. Spray foam insulation can significantly reduce energy bills and make your home feel more comfortable while reducing noise and blocking pests from entering.
