Foam-Control MAX™ Graphite Polystyrene (GPS)
Next Generation Insulation Powered by Graphite™
Foam-Control MAX™ is a next generation insulation product line with a maximum R-value powered by graphite. Foam‑Control MAX is a premium grade insulation manufactured to provide architects, specifiers, distributors, and contractors all the features and benefits inherent in a high quality insulation.
Foam-Control MAX Benefits
- R-value – Foam-Control MAX has a maximum R-value that never changes over time.
- Strength – Foam-Control MAX comes in compressive strengths of 10, 15, and 25 psi.
- Moisture Resistance – Foam-Control MAX is a closed cell polystyrene insulation and is resistant to moisture gain.
- Vapor Permeable – Foam-Control MAX allows moisture vapor to move through its structure.
- Drying Potential – Foam-Control MAX rapidly releases absorbed moisture.
Powered by Graphite.
Foam-Control MAX is a graphite polystyrene rigid foam insulation that delivers maximum energy efficiency, cost effectiveness and sustainability. Planners, architects, contractors and builder-owners benefit from Foam-Control MAX because of the special advantages this material offers.
Foam-Control MAX is comprised of many small pockets of air within a polymer matrix containing graphite. The graphite reflects radiant heat energy like a mirror, increasing the material’s resistance to heat flow or R-value.
