Attic insulation is different from other kinds of insulation in a number of ways. The primary distinction is that it supplies insulation and air sealing all in one product. This helps to keep heat from moving in the winter and out of the home in the summer. Additionally, it creates a strong barrier against mold growth, pollutants and rodents.

What is spray polyurethane foam insulation?

SPF is an alternative to traditional building insulation, such as fiberglass. It consists of two chemicals that are mixed at the tip of a gun, which is sprayed onto roof tiles or concrete slabs, or through holes drilled into wall cavities. The chemicals, isocyanate and polyol resin, react with each other and expand rapidly to form an insulating foam. The resulting material is long-lasting and has a high R-value, meaning it keeps homes warmer or cooler for longer than other types of insulation.

It is also resistant to water, so it does not absorb moisture or vapor and helps prevent mold, mildew and other harmful substances from growing within the home. It is a good choice for homeowners who want to minimize power bills, as it has been proven to reduce energy consumption by up to 50%.

While there are DIY kits available for individuals who are confident in their skill set and would like to install the insulation themselves, it is usually recommended that professional installation be undertaken. The mixture of isocyanates and polyols involved in the manufacturing process can be dangerous to handle without a lot of training. The chemicals can cause irritation to the eyes, gastrointestinal, and respiratory tracts, and prolonged exposure can even lead to chemical bronchitis.
