You’ve probably heard of spray foam insulation, but what exactly is it made of and how does it insulate? At South Central Services, we answer this question weekly from customers curious about this energy efficient insulation.

Spray foam attic insulation is made of polyurethane, a type of plastic that’s created when two liquid chemical components undergo a rapid chemical reaction to form the plastic foam. It’s typically applied during the rough-in stage in construction, when the foam is sprayed into wall cavities, attic hatches, and other spaces that would be difficult to reach with conventional insulation materials.

When installed properly, this insulation creates an air seal that stops the flow of heat in and out of a home. This prevents heat from flowing into a house during the winter and out of it during the summer, cutting homeowners’ utility bills by an average of 50% right away.

In addition to stopping airflow, this type of insulation also stops moisture from leaking into the home. This prevents places like attics and crawl spaces from becoming damp, humid environments that require expensive dehumidification systems.

Another benefit of spray foam insulation is that it helps reduce the amount of airborne allergens, such as dust and pollen, from entering the home. This translates to fewer runny noses and itchy eyes in the spring, as well as less congestion on HVAC air filters that can’t work effectively if they’re filled with dust and other pollutants.
