In insulation terminology, R-value refers to how effective the insulation is. Basically, the higher the R-value, the better the insulation material. Spray foam insulation has one of the best R-values. Furthermore, because it is so cheap, you can conveniently add layers of insulation to get the same level of insulation you would have gotten from expensive substances like cellulose insulation. Moreover, because spray foam insulation has been in use for a very long time, you can get competitive prices with relatively little effort. By installing an effective insulation material, you will eventually be able to save on utility bills in the long run.

Types Of Spray Foam Insulation
In the market today, two types of spray foam insulation are commonly used. First is the open type and the other is the closed type. The main difference lies in the structure between the small bubbles (cells) that make up the foam. Open cell foam is full of cells that aren’t completely encapsulated. In other words, the cells are purposefully left open. This leads to a softer and consequently more flexible foam. On the other hand, closed cell foam is made up of cells that are, as the name suggests, completely closed. The cells are compressed together, so as to block all the air and moisture from getting inside the foam. Because of this, closed cell foam is much more rigid and stable than open cell foam.
R-Values Of Spray Foam Insulation
As stated before, spray foam insulation has a high R-Value per inch. In fact, its R-Value is even higher than that of products such as batts. Closed cell spray foam can offer an R-6 or R-7 per inch. This translates to R-24.5 for a 3.5″ deep wall cavity. This is very important in situations where your local area code requires an R-21 for the wall, which is the most common scenario. Open cell spray foam on the other hand typically has an R Value of 3.5 per inch, and another drawback is that it does not form a tight air seal. Nonetheless, it performs much better than any form of batt for stopping air flow, and it is an affordable solution for those on a tight budget.
