WHAT ARE THEDIFFERENCES BETWEENOPEN AND CLOSED CELL

SPRAY FOAM INSULATION?

LEARN ABOUT THE

BIG DIFFERENCES BETWEEN

OPEN AND CLOSED CELL SPRAY FOAM

BEFORE DECIDING WHICH ONE TO HAVE INSTALLED.

CLOSED-CELL FOAMS

are made up of trapped gas bubbles

that are formed as the foam expands and cures.

The blowing agent

in open-cell foams is released

into the atmosphere when it expands and cures.

In closed-cell spray foam,

the trapped gas increases

the cured foam's insulation capability.

OPEN-CELL FOAM

typically has R-values of 3.5-4.0,

whereas closed-cell foam has R-values of 6.0-6.5.

Open-cell spray foam

is best for structures where space

is not limited, such as a crawl space or attic.

Closed-cell spray foam

is best for getting high R-values

in shallow areas of a structure.

The R-values

of closed-cell foam

tend to change overtime

If you are on a tighter budget

then closed-cell foam

would be your best option.

Open-cell foam

is vapor semi-permeable and

closed-cell foam is vapor semi-impermeable.

Closed-cell spray foam

is the best option for preventing

liquid water from getting into a structure.

Closed-cell foams

are much denser and

more common than open-cell foams.
