When it comes to home insulation, spray foam is a highly effective option that can save you up to 50% on your energy bills. It's more expensive than other types of insulation, but it has higher insulation ratings and can last up to 80 years. Installing spray foam is easier during the construction of a new home, but it can also be done in existing homes with a bit more time and money. Before making the decision if spray foam insulation is worth the investment, there are several factors to consider.
The expanding agent used in spray foam has a high global warming potential, so it's important to take safety precautions to mitigate any potentially harmful effects. Additionally, closed-cell spray foam is necessary in areas that require a moisture barrier. Open-cell foam insulation is not as strong an insulator as closed-cell, but it is cheaper and expands more. The improved insulation provided by spray foam can offset environmental damage, and the hermetic seal created by the foam does not absorb moisture, protecting walls from water damage and mold.
Closed-cell spray foam has a lower application configuration and takes longer to apply than open-cell spray foam, as it will completely seal the area being insulated. Spray foam insulation is so effective at increasing the energy efficiency of your home that most homeowners who install it find it worth the price. Hiring a professional can ensure that the installation is done correctly and safely.
