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.

Which Works Best

The difference in closed-cell foams can determine whether you need, say, EVA or Volara foam for home, recreation or business needs. Breathable open-cell foam is the foam of choice if you want to prevent mold, and you can choose organic options. Note that both can be for outdoors use. Before making your decision, also consult foam safety specs for open-cell and closed-cell foam.

Consult the Experts

In this online era, it’s easier to consult experts. When you are perusing ecommerce websites, do your research to learn more about the company’s history, experience and expertise on foam products.

When it comes to closed cell foam vs. open cell foam, both types have their own advantages and disadvantages. Closed cell foam is more durable and provides better insulation and soundproofing capabilities, but it is also more expensive and not as breathable as open cell foam. Open cell foam is much more lightweight, breathable, and affordable, but it is not as durable and does not provide as good of an insulation value as closed cell foam. Ultimately, the best choice will depend on the application and the budget of the project.
