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.
Open cell foam insulation vs closed cell.
A foams r value is its resistance to heat flow or in other words how well they insulate.
Open cell foam.
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.
Closed cell foam has a higher r value than open cell foam usually about 6 0.
Closed cell foam can be over three times that with a density of 1 75 pounds per cubic foot or more.
However closed cell will give.
Because the cell walls are broken the foam is softer.
One application is able to fill any open areas between studs.
At the end of the day open cell spray foam insulation is an affordable option opposed to closed cell.
This makes for more sturdy products that serve as great insulation.
Closed cell foam is much denser than open cell foam.
Because of this closed cell foam is much more rigid and stable than open cell foam.
Closed cell foam is made of uniform cells that maintain their own shape.
Closed cell foam.
Because of this the foam expands making it able to cover those hard to reach areas.
