What is Polyiso Foam Insulation? A Deep Dive
Polyisocyanurate, commonly known as polyiso, is a closed-cell, thermoset plastic foam used extensively in the construction industry as thermal insulation. It stands out due to its high R-value per inch, excellent fire resistance, and versatility in application. Unlike some other insulation materials, polyiso’s performance isn’t significantly affected by temperature changes, making it a reliable choice in a wide range of climates.
A Brief History and Evolution
Polyiso foam insulation emerged in the late 1960s as an improvement over polyurethane foam. The modification of the chemical formulation resulted in enhanced fire resistance and thermal stability, quickly establishing polyiso as a preferred option in commercial and residential buildings. Over the years, advancements in manufacturing processes have further improved its performance and broadened its application range.
Core Concepts and Advanced Principles
At its core, polyiso’s insulating properties stem from its closed-cell structure, which traps gas within the foam matrix. This trapped gas resists heat transfer, providing exceptional thermal resistance. The isocyanurate chemical structure contributes to its fire resistance. Advanced formulations may include additives that further enhance its fire performance, moisture resistance, or compressive strength. Understanding these principles is crucial for selecting the right type of polyiso for a specific application.
