Many homeowners and contractors will find that spray foam insulation is the best option available for their insulation needs. However, while narrowing down the choices this far may be easy for many people, choosing between the options of open and closed cell foam can be a bit more difficult. This is because many people fail to understand the true differences between these two products and how these differences can impact the way their insulation works.

Below you will learn more about these differences, as well as the pros and cons that accompany both open and closed cell foam so that you can ultimately make an informed decision regarding which type of insulation is right for you:

Blocking Moisture

Closed cell foam makes use of small gas bubbles inside each cell that burst during the application process causing the cell to become completely closed. This allows the cells to bond together to create a virtually impenetrable moisture barrier.

When choosing open cell foam, the air bubbles inside each cell will remain intact during the application process. As a result, this insulation is able to absorb moisture rather than creating a barrier against it.

Consequently, open cell foam will often prove to be the inferior product when insulating exterior walls, attics, and basements, since these areas of the home will require the ability to block out moisture.

Absorbing Sound

When sound waves hit closed cell insulation, the reaction is much like running into a brick wall, the sound is likely to go flying in all directions. This is because the solid surface created by closed cell insulation does not have the ability to absorb anything.

Open cell foam on the other hand, has the benefit of many microscopic air bubbles that allow for the absorption of sound. Consequently, when sound waves hit this insulation, they will simply be absorbed and deadened. This allows for a very impressive sound barrier when insulating a play room, music room, conference room or other area where privacy is of the utmost importance.

Standing Up To The Test Of Time

One of the biggest problems that most insulation materials have is a process known as settling. Settling occurs over time as the insulation loses its elasticity and therefore begins to lose volume. When this happens, the effectiveness of the insulation will become greatly compromised.

Since closed cell foam does not have any gaps or spaces in its molecular structure, it will experience far less settling than open cell foam. This allows it to last significantly longer without being replaced. To learn more, contact a company like Bios Environments with any questions or concerns you have.
