Open and closed cell foam insulation are popular types of insulation that offer a ton of benefits. However, with no knowledge about these 2 forms of insulation can make things tricky and confusing making it harder to choose the best from the other. One reason is that both forms of insulation also have weaknesses. Therefore, choosing the wrong insulation will lead to trouble for you and your home for sure. Let’s understand some of the differences between the two to make it easier to choose.
- The Density or Weight – When it comes to density or weight, open cell foam insulation sits higher compared to closed cell foam. The density of both insulations are as follows: – Open Cell – .5 pounds per cubic foot and Closed Cell – 1.75 pounds per cubic foot.
- The Cells – Cells are known to play a huge role when it comes to the foam. For instance; the cells of open cell foam insulation are in the manner of being open which is kept like that purposely. The reason for the purpose is that it helps the foam softer and less encapsulated. On the other hand, the cells of closed cell foam insulation are known to be close to each other which again is done purposely. Being close of cells means moisture and air don’t come in contact with the foam.
- The R-Value – 6.0 per inch is the R-Value of open cell foam insulation while 3.5 per inch is the R-Value of close cell foam insulation.
