Open Cell Foam Insulation Vs Closed Cell

At the end of the day open cell spray foam insulation is an affordable option opposed to closed cell.

Open cell foam insulation vs closed cell.

However closed cell will give. Closed cell foam has a higher r value than open cell foam usually about 6 0. Open cell foam is made of irregularly shaped cells that are linked together. Because the cells are closed and have their own cell walls they are more rigid and trap a large amount of air.

Open cell foam insulation is lightweight pliable and easy to work with whereas closed cell foam is rigid and very dense. Open cell insulation is also a great option for soundproofing. Because the cell walls are broken the foam is softer. Closed cell foam.

A foams r value is its resistance to heat flow or in other words how well they insulate. Closed cell foam can be over three times that with a density of 1 75 pounds per cubic foot or more. For example if you needed to run new wiring open cell spray foam is going to be much easier to work with because it is so pliable. Closed cell foam is much denser than open cell foam.

Most open cell foam has a density of about 5 pounds per cubic foot. Closed cell foam is made of uniform cells that maintain their own shape. Because of this the foam expands making it able to cover those hard to reach areas. Because of this closed cell foam is much more rigid and stable than open cell foam.
