WebAug 8, 2024 · Closed-cell polyurethane foams use air to provide a cushion. These closed-cell foams are filled with tiny, closed air bubbles or pockets. Over time, repeated compression causes air to leak out of the closed cells. Because the cells shut it out, air cannot return to the foam. This process of exhalation deflates the foam. SMALL SPRINGS

Closed cell foam is more impermeable to water, vapor, and air. Therefore, it is less likely to be structurally impacted by the effects associated with water damage: mold, mildew, rot, and bacteria. See more In closed cell foam, the cells are like tiny air pockets piled together in a compact configuration, resembling inflated balloons nestled tightly together. Due to the closely packed cells, closed … See more Closed cell foam is a better air barrier than open cell foam, and can be used to control airflow as it is less permeable. For example, closed cell foam could be an effective gasket or seal for climate-control by keeping hot … See more Created using a similar process as closed cell foam, open cell foam is designated to be vapor semi-permeable as the formation of the cells in the material are broken, rather than closed. Similar to the holes inside a sponge, air … See more Open cell foam has a higher possibility of absorbing water than closed cell foam, which can lead to degraded performance, especially for thermal applications.
