Closed Cell VS Open Cell Spray Insulation

When it comes to insulating your house, you have a veritable laundry list of options at your disposal. There are simply a variety of ways you can go about insulating your domicile or whatever it is that you want to insulate. There are some alternative options to the traditional route of regular old insulation. One of those options is rather new fangled: spray insulation. Don't, for one minute, think that such a decision is cut and dry as it stands. Rather, there are options within the world of spray insulation for which you will have to choose.

One of the most important decisions is: should you choose closed cell or open cell spray insulation? This brief article should help you with that decision.

What Is Open Cell Spray Insulation?

Whenever spray foam insulation is sprayed, it will eventually, usually quickly, congeal. Whenever it congeals, it congeals in a way that leaves tiny cells behind. When these tiny cells aren't sealed off, they are known as open cells. The cells in open spray insulation are not completely closed, allowing air to fill the space around the insulation. It is a bit less dense than closed cell spray insulation and has a springy, sponge like appearance to it.  

What Is Closed Cell Spray Insulation?

Unlike open cell spray insulation, after its quick acting congealment, the closed cell spray insulation foam turns into insulation that does not leave tiny cells behind. It expands into pockets of foam with gas trapped inside. Opposed to open cell spray insulation, it actually is not fluffy in appearance at all, and it is quite dense and noticeably heavier. It is an incredibly compact form of insulation and easy to transport and ship, despite the noticeable weight difference to its open cell spray insulation brethren. It is a bit more all-purpose than open cell spray insulation.

Advantages Of Open Cell Spray Insulation

One big advantage of open cell spray insulation over closed cell spray insulation is the cost. Usually open cell insulation is less expensive to purchase and have installed than closed cell. Due to the fact that open celled spray insulation rapidly congeals and the chemical bonding process leaves tiny open cells behind makes it a markedly less complex process than closed cell spray insulation.

It is also much easier to "handle." After the spray has been applied, open cell spray insulation is much easier to move and replace than closed cell spray insulation due to the fact that it so much less dense, much lighter, and much less bulky. Open cell insulation also shifts more easily, which means that as your house shifts, the insulation can accommodate that shift and move with it.

Advantages Of Closed Cell Spray Insulation

The fact that closed cell spray insulation is much more densely congealed means that it functionally works as insulation better than open cell spray insulation. While open cell spray insulation should mainly be used in areas inside out of the house, closed cell spray insulation can be used in any freestanding building.

Closed cell insulation tends to be stronger than open cell insulation, which means it is a great insulation to use to fortify walls and ceilings. Closed spray is often used for roofs or attics, as due to how tightly chemically bonded closed cell spray insulation is, it does wonders for keeping out water or other liquids that may try to make their way into your home.

Spray insulation is an amazing alternative form of insulating your house. Often times, it is cheap, efficient and does the job that it set out to do, insulate your home from the harshness of the outside world!
