Closed cell is a type of foam in which the “cells” are closed and tightly pressed together, contrasting with the open, interconnected cells of the open-cell, or traditional polyurethane foam variation. This means that water rolls off the foam rather than passing through it. With higher density and greater pressure resistance, this malleable material comes in a variety of forms. From the rigid polyethylene (cross-poly) foam to the less dense EVA foam, and the squishy feel of Flotex, closed-cell foam is a versatile material offering a tight seal and enhanced stability.

Closed-cell foam is a type of foam material that has closed cells, which means the cells are filled with gas and not connected to each other. It is denser and more rigid than open-cell foam, and has a higher R-value, making it a more effective insulation material.
Common uses for closed-cell foam include insulation for walls, roofs, and foundations, packaging materials, gaskets and seals, flotation devices, and athletic equipment.
The R-value of closed-cell foam insulation can range from R-6 to R-7 per inch, depending on the density of the foam.
Yes, closed-cell foam can be used in outdoor applications. It is water-resistant, durable, and provides excellent insulation, making it ideal for outdoor furniture cushions, flotation devices, and boat seats. Its dense structure prevents water absorption, helping it withstand harsh weather conditions and prolonged moisture exposure.
Low-density closed-cell foam is less rigid, lighter, and has a lower R-value, meaning it provides less insulation. It’s often used in applications where flexibility and ease of handling are important. High-density closed-cell foam, on the other hand, is more rigid, heavier, and has a higher R-value, offering better insulation and durability.
The advantages of using closed-cell foam include high R-value, moisture resistance, durability, soundproofing, versatility, pest resistance, and fire resistance.
Closed-cell foam can last up to 20-30 years depending on the application and environmental conditions it’s exposed to.
