Closed Cell insulation provides a high amount of security to what you are insulating. It is also the most popular type of insulation used in remodeling and new construction applications. It can provide support to structures due to composition of their cells. It protects against water damage and provides a higher R-value per-inch compared to your other types of insulation. You may be wondering what R-value is: when dealing with insulation the R-Value is determined by its resistance to heat flow. Higher resistance typically results in better insulation, and that is also where energy savings come into effect. When you choose spray foam insulation, not only are you providing your home with the best quality of insulation, but you are also saving money and energy in the process. Closed cell foam usually has a R-Value of 7 per inch, however, open cell has an R-Value of 3.5 per-inch.
