One question we are always asked is what is the best insulation for your home? Is it batt, loose fill rigid or spray foam? Each type of insulation works a little bit differently depending on the insulation project. However, one type of insulation that is best for any type of insulation project is closed-cell spray foam.
What’s the difference between open-cell and closed-cell insulation?
When we talk about open-cell and closed-cell insulation it has to do with any air cells that are left after the insulation is installed. With traditional types of insulation, these are almost always open-cell as there will be air pockets left.
With spray foam, there is also open-cell insulation. In this case, there are small air pockets left by the foam which reduces its R-value – the ability to resist heat loss.
