Open Cell And Closed Cell Spray Foam Insulation

Open cell foam is full of cells that aren t completely encapsulated.

Open cell and closed cell spray foam insulation.

The microscopic cells within open cell foam are just that open which give it a soft fluffy feeling. Importance of knowing the difference between open cell vs closed cell spray foam insulation. In density whereas closed cell ranges from 1 7 to 3 0 lb cu. Both closed cell spray foam and open cell spray foam insulation can be used effectively in commercial building designs to allow the building to achieve energy efficiency and consistent performance.

In other words the cells are deliberatly left open. Closed cell foam is more rigid. Now lets get to it. A spray insulation is referred to open cell or closed cell because of the difference between the small bubbles cells that make up the foam.

Let s take an apples to apples look at a cost comparison between open cell and closed cell spray foam. Open cell spray foam vs closed cell cost. Ft of foam material is weighed. Open cell tends to be roughly 0 5 lb cu.

Closed cell foam is roughly four times as dense as open cell for insulation applications. However both foams are air barriers and it is the air barrier that makes foam such an excellent insulation. To ascertain foam density one cubic foot cu. It is important to be aware of the difference between open cell vs closed celled spray foam insulation cost uk.

Closed cell foam is much more expensive than open cell foam. Closed cell foam is around 6 6 per inch as compared to 3 8 per inch in open cell. Closed cell spray foam on the other hand is also called medium density or 2 0 lb foam. The cost to insulate an entire existing home with spray foam varies by factors such as the size of the insulated area difficulty of the job thickness of foam applied and type of foam used.

When applied on the interior open cell spray insulation provides performance advantages that differ from those of closed cell spray foam used on the exterior. If an installer was to install the incorrect cell type foam it could cause the insulation to work ineffectively. We often compare the texture of open cell foam to a sponge or even angel food cake. In density or even higher for certain applications.

This makes the foam a softer more flexable material.
