Closed cell spray foam on the other hand is also called medium density or 2 0 lb foam.
Open cell and closed cell spray foam insulation.
Let s take an apples to apples look at a cost comparison between open cell and closed cell spray foam.
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.
Closed cell foam is made.
We often compare the texture of open cell foam to a sponge or even angel food cake.
The microscopic cells within open cell foam are just that open which give it a soft fluffy feeling.
In density or even higher for certain applications.

In other words the cells are deliberatly left open.
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.
Closed cell foam is much more expensive than open cell foam.
Closed cell foam is roughly four times as dense as open cell for insulation applications.
Closed cell foam is around 6 6 per inch as compared to 3 8 per inch in open cell.

This makes the foam a softer more flexable material.
Ft of foam material is weighed.
However both foams are air barriers and it is the air barrier that makes foam such an excellent insulation.
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.
Importance of knowing the difference between open cell vs closed cell spray foam insulation.
Icynene open cell and closed cell spray foam insulates and air seals in one step.
If an installer was to install the incorrect cell type foam it could cause the insulation to work ineffectively.
