Product Description
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).
