Closed Cell Foam vs. Open Cell Foam: What’s the Difference
Knowing the difference between open-cell foam and closed-cell foam is important to making the right choice for your home, business or industrial needs. The pros at FoamOrder offer this quick guide to closed-cell foam vs. open-cell foam.
What’s the difference between open-cell foam and closed-cell foam? It’s all in the name. Open-cell foam has open, interconnected cells (or, spaces) that absorb water and other substances. Denser closed-cell foam has closed (or squished together) cells, which seals out water, air and more.
About Open-Cell Foam
Open-cell foam is softer and more flexible than closed-cell foam, which is why it’s popular for use in indoor and outdoor furniture cushions. For example, open-cell foam is used to make popular memory foam mattresses. If you’re allergic or want an environmentally friendlier choice, you can choose organic open-cell foam for cushions and more. FoamOrder has 100% natural foam choices. We also offer outdoor dry-fast foam, with large open cells that let water drain quickly. This contributes to mildew and mold-free outdoor furniture cushions.
About Closed-Cell Foam
Closed-cell foam types differ in density and texture. It’s a stronger and higher-density foam than open-cell foam. And, it’s waterproof. Closed-cell foam also blocks the absorption of air, which is why it’s a popular choice for insulation. You’re probably most familiar with closed cell foams like Flotex, which is what yoga mats are made from.
