What is the Difference Between Open-cell and Closed-cell Polyurethane Foams?
Open-cell foam is soft - like a cushion or the packaging material molded inside a plastic bag to fit a fragile object being shipped. The cell walls, or surfaces of the bubbles, are broken and air fills all of the spaces in the material. This makes the foam soft or weak, as if it were made of broken balloons or soft toy rubber balls. T

​

he insulation value of this foam is related to the insulation value of the calm air inside the matrix of broken cells. The densities of open-cell foams are around 1/2 to 3/4 of a pound per cubic foot.

Closed-cell foam has varying degrees of hardness, depending its density. A normal, closed-cell insulation or flotation polyurethane is between 2 and 3 pounds per cubic foot. It is strong enough to walk on without major distortion. Most of the cells or bubbles in the foam are not broken; they resemble inflated balloons or soccer balls, piled together in a compact configuration. This makes it strong or rigid because the bubbles are strong enough to take a lot of pressure, like the inflated tires that hold up an automobile. The cells are full of a special gas, selected to make the insulation value of the foam as high as possible.

The advantages to Closed- cell versus Open- Cell include greater strength, more resistance to air leakage and water vapor. Has a higher R - Value and because it is so dense that it is unlikely to breath better then open cell during a fire. No air to fuel the fire! Adds as a vapor barrier as well. This is the only product that should be sprayed below grade.

We believe at BDK Foam Insulation that the consumer should be more educated on the products they buy. So don't just take our word on this, check out the world wide web.
