Sheet1 ISO insulation, commonly known as polyisocyanurate (polyiso), is a highly effective rigid foam insulation material widely used in commercial roofing and building applications due to its excellent thermal resistance and fire safety properties.
Polyisocyanurate insulation, often referred to as ISO, is a type of rigid foam insulation that is known for its high R-value per inch, typically ranging from R-5.7 to R-6.5. This makes it one of the most efficient insulation materials available, particularly for commercial applications. 1.5" = R-8.6 minimum. 3" = R-17.2 min. 3.5" = R-20 min.
