Not all thermal barriers are equal. AzoCore is the foamed polyurethane with the lowest material thermal conductivity available. It helps aluminum fenestration systems achieve U-factors that meet demanding energy standards, including ENERGY STAR, Passive House, and the International Energy Conservation Code.

AzoCore is engineered for single and dual cavity profiles where performance isn’t negotiable. It is strong and durable, and it maintains thermal efficiency over the life of the system. If the specification demands high thermal performance for years to come, AzoCore is the answer.
