Government studies indicate that your home may be losing up to 40% of its energy because of air
infiltration. Spray foam insulation is the most effective way to stop this from happening!
The greatest challenge in the Insulation Industry is not technology, expertise or cost effectiveness. The
greatest challenge is Education.
Our certified technicians are specialized in providing different customizable and environmentally
friendly insulation solutions. Contact 4D Roofing & Construction today to discuss your options.
Closed Cell vs. Open Cell Foam Insulation
Closed cell: Foams consist of trapped gas bubbles formed during the foam’s expansion and cure. These
gas bubbles consist of the blowing agent and are permanently locked into place during the curing of the
foam. The trapped gas increases the insulation capability of the cured foam. The cured foam must be
strong and of a medium density in order to lock in the gas bubbles. The foam’s strength, coupled with its
closed cell nature, enable it to resist liquid water and function as a vapor retarder.
Open cell: The blowing agent gas is not trapped by the forming cells and instead is released to the
atmosphere during foam expansion and curing. The foam cells have “holes” in their walls, enabling them
to interlock and interconnect. The spaces within the cells are filled with atmospheric air, much like a
sponge. Due to its porous nature, open cell foam does not resist liquid water or water vapor (humidity).
Without trapped gas bubbles, open cell foams also do not need to be as strong, and therefore, are less
dense than closed cell foams.
