Closed Vs Open Cell Spray Foam Insulation

Closed cell and open cell foam are insulation products that effectively insulate a home. They accomplish the task in different ways. Let’s dive into this.

Both products offer comparative strengths and weaknesses. One is not necessarily better than the other. It depends on the type that will fit your needs. Generally, closed cell spray foam insulation is the most preferred product here in MA because they generally deliver a higher R-value.

The open cell foam is full of cells that are not completely encapsulated. The cells are left open making the foam a softer, more flexible material. With closed cell foam, it is made up of cells that are completely closed. The cells are pressed together, so air and moisture are unable to get inside the foams. These results make closed cell foam more rigid and stable than open cell foam. In addition, closed cell foam is much denser than open cell foam. Based on the resistance to heat flow or how well they insulate, closed cell foam has a higher R-value than open cell foam. It has higher ratings that go up to almost seven per inch. The higher rating makes closed cell foam better at keeping heat in or out of a structure. In addition, closed cell foam is very useful for a lot of applications that require moisture and shock resistance, heat, and sound insulation. This makes it the ideal insulation solution for commercial properties for being sustainable and durable.

Closed cell spray foam has much to offer and it can come in a slightly higher material cost than open cell. But here in MA, that modest product cost differential for closed cell insulation passes the overall value test. That cost is returned rapidly in the form of lowered home energy costs.
