Polyisocyanurate (Poly-Iso) insulation is suitable for applications that require a Flame Spread Index of 25 or less and a Smoke Developed Index of 450 or less when tested as per ASTM E84. These are typical requirements for pipe insulation located in non-plenum locations so polyisocyanurate insulation is particularly ideal for use as pipe insulation in the non-plenum areas of commercial buildings. Polyisocyanurate can be used within the service temperature range of -297°F to 300°F (-183°C to 149°C).
GIC Companies fabricate polyisocyanurate (Poly-Iso) in many shapes and sizes to meet your exact requirements. This rigid insulation is supplied in the form of bunstock into sheets, pipe shells, tank and vessel coverings, and other shapes for a variety of thermal insulation applications. Polyisocyanurate insulation features improved dimensional stability over a wider range of temperatures.
