Because of this closed cell foam is much more rigid and stable than open cell foam.
Open cell foam insulation vs closed cell.
Open cell insulation is also a great option for soundproofing.
Closed cell foam.
However closed cell will give.
Closed cell foam is much denser than open cell foam.
Open cell foam is made of irregularly shaped cells that are linked together.
Closed cell foam is made of uniform cells that maintain their own shape.
A foams r value is its resistance to heat flow or in other words how well they insulate.
At the end of the day open cell spray foam insulation is an affordable option opposed to closed cell.
Closed cell foam can be over three times that with a density of 1 75 pounds per cubic foot or more.
One application is able to fill any open areas between studs.
This makes for more sturdy products that serve as great insulation.
Because the cell walls are broken the foam is softer.
Because the cells are closed and have their own cell walls they are more rigid and trap a large amount of air.
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.
Because of this the foam expands making it able to cover those hard to reach areas.
Most open cell foam has a density of about 5 pounds per cubic foot.
