Both open and cell foam insulation have their own set of benefits however, it does become confusing when it comes to the choosing part between the 2 for home insulation. Why confusing? That’s because along with benefits, these forms of insulation also have their own weaknesses. Furthermore, if you choose the wrong insulation things can get very messy for you and your home. Make sure you understand these differences in order to choose the correct one.

  1. Density – Between open and closed cell foam insulation, open cell foam insulation is highly denser with .5 pounds per cubic foot. While the closed cell foam is less-denser with 1.75 pounds per cubic foot.
  2. Cells – The foam is all that matters between the where cells play a huge role. The open cell foam has cells that are open and kept it like that on purpose. The purpose of this is to make it into a flexible and softer material with less encapsulation in nature. While the closed cell foam has cells that are located closer to each other and done so deliberately. This ensures moisture and air do not come in contact with the foam.
  3. R-Value – Open and closed cell foam insulation have their set of R-Values with 6.0 per inch for closed and 3.5 per inch for open cell foam. The R-Value of closed cell foam makes it more reliable to be used in low-temperature conditions while the R-Value of open cell foam is the opposite.

Both forms of insulation are good however, you have to be careful in choosing the best form of insulation in Canberra.
