There are two types of spray foam insulation: open cell and closed cell. There are pros and cons to both types. Many homeowners choose closed cell spray foam for the following advantages and benefits:
1. Moisture Barrier – Closed cell spray foam helps to keep unwanted air out of your home, and it also helps to keep unwanted moisture out as well. Not only does closed cell spray foam help to prevent water and moisture from entering your home, it is also impermeable to water. This means that any water it does come in contact with will not be absorbed into the insulation.
2. Energy Efficient – Closed cell spray foam is an extremely effective insulator and therefore helps to keep your home warmer in the winters and cooler in the summers. This allows your HVAC system to work less and costs you less money each month on your energy bills.
3. Long Life – Spray foam will last many, many years before needing to be replaced. It is made up of inert polymer, which gives it a very long lifespan.
4. Greener Home – You will be using less energy to heat and cool your home with closed cell spray foam, which means your carbon footprint will be smaller.
5. Effective Insulator – Closed cell spray foam is an extremely effective insulator. It has an R-value of approximately 7 per square inch, which is the highest on the market. One of the reasons it is so effective at insulating is because, once it is sprayed, it expands and is able to cover all areas, including difficult to reach ones.
