Low Permeability Foam
Permeability is a material’s ability to let gases or liquids pass through it. In foam applications, low permeability is essential. It helps block air, moisture, dust, and other contaminants from entering a system. Low Permeability Foam offers a reliable solution for sealing, insulation, and protection—without losing flexibility or durability.
Merryweather Foam specializes in custom foam fabrication, providing high-performance Low Permeability Foam solutions that are precisely tailored to your specifications. This material comes in a wide range of densities and is easily customized. Every solution meets top industry standards for quality, performance, and dependability.
