attic insulation is an alternative to fiberglass batts that combines the functions of air and moisture control, thermal and sound barriers. The result is a more insulated home or commercial building with lower energy costs and improved comfort. It also reduces the influx of outdoor pollutants and allergens, enhancing indoor air quality. It is long-lasting, minimizing replacement needs and waste. Additionally, it is environmentally beneficial, reducing energy consumption for heating and cooling which contributes to reduced carbon emissions.
Cost Benefits of Spray Foam Insulation in Florida’s Climate
Whether you have an existing home, new construction, or pole barn that needs to be insulated, the process begins with the crew removing any old insulation from the area being sprayed. They will then run a hose from the high-end rig to the areas where insulation is needed – usually attics, crawl spaces, rim joist in existing homes, and unfinished walls of new construction or pole barns.
Then, depending on the climate, they may spray two inches in walls and three inches in roofs to meet energy codes. In some cases, they may suggest a thicker application for better performance and savings.
Closed cell spray foam is more expensive than open-cell, but it is physically stronger and seals tighter, meaning that less of it will need to be replaced over time. Some contractors use low-GWP blowing agents, such as HFOs, which can significantly decrease the amount of CFCs, HCFCs, and HFCs that are released into the atmosphere each year. The choice of blowing agent also affects the flammability of the spray foam, which can impact the fire rating of the insulation.
