EPS Tech Data
Benchmark Foam offers complete EPS (Expanded Polystyrene) technical data in accordance with industry standards and ASTM C578 specifications. Our EPS materials are tested and crafted with a strong emphasis on quality and performance.
Insulation Performance and R-Values
One of the primary metrics used to measure insulation efficacy is the R-value, which indicates the material’s thermal resistance. According to Federal Trade Commission guidelines, the R-value at 75°F should be used when calculating R-values for residential construction. This approach ensures consistency and accuracy in insulation performance assessments across projects, optimizing energy efficiency in residential buildings.
EPS R-Values strictly adhere to the ASTM C-578 standard so that you can count on the same thermal performance with every project. EPS is a good thermal insulator but should not be compared to polyisocyanurate materials that may use different conditioning standards, such as RIC-TIMA or PIMA. EPS insulation is engineered to provide dependable thermal performance over time, making it a great choice for residential and commercial applications where consistent insulation is important.
Flammability Considerations
Like many construction materials, EPS is combustible and should be installed with appropriate safeguards. Benchmark Foam’s EPS should meet all current model building code requirements to ensure safe use, providing adequate protection or separation from occupied areas. EPS will not contribute to a flame as when exposed to high heat; EPS does not burn; it melts. However, caution must be taken to install in accordance with fire safety standards and to not expose to fire ignition sources
Moisture Resistance and Breathability
EPS insulation stands out due to its impressive moisture resistance, achieved through a closed-cell structure that significantly reduces moisture absorption. Although EPS is not a vapor barrier, its structure allows it to “breathe,” eliminating the need for costly venting, as other insulation materials require. This unique breathability makes EPS a versatile option that helps prevent moisture accumulation within wall and roof structures, supporting a healthy and moisture-resistant building environment.
UV Exposure and Protection
EPS insulation is very durable but may dust or discolor its surface if exposed to prolonged UV sunlight. For optimal performance, EPS should be covered or finished when exposed to sunlight for long periods. This protection preserves the material’s integrity and appearance and maintains it as intended for the life of the installation.
ASTM C578 Compliance for Reliable EPS Technical Data
EPS technical data from Benchmark Foam complies with ASTM-C578, a widely accepted industry standard for testing EPS insulation. This standard guarantees that all aspects of EPS performance (R-Values, flammability, moisture resistance, UV stability) are measured and reported accurately. Clients can trust the information provided to make informed design choices and achieve the best insulation solutions for their projects.
