The foams are fully catalyzed and fortified with fire-resistant additives and blowing agents. These specialized chemicals contribute to their outstanding insulation properties, characterized by a low K value, ensuring exceptional thermal efficiency and fire resistance. These panels are designed to meet stringent safety standards.
Additionally, these sandwich panels exhibit remarkable compressive strength, in compliance with ASTMD - 2326-70 standards. They are engineered to withstand various environmental factors, offering both structural integrity and energy-saving capabilities.
Known for their versatility and efficiency, PUF and PIR wall panels are a preferred choice in modern construction, offering an optimal balance between insulation, durability, and fire safety for a wide range of applications.
