Product Summary
IKOTherm III is a rigid, polyisocyanurate foam insulation with high thermal properties. It is constructed from closed cell polyisocyanurate foam core bonded on each side to coated glass fiber facers during the manufacturing process. IKOTherm III polyisocyanurate foam insulation is ideally suited for hot and cold applied Mod-Bit roofing systems and BUR roofing systems. IKOTherm III polyisocyanurate foam insulation is dimensionally stable and can be sized with ease. It is also lightweight and easy to handle. It has a high thermal R-value that provides outstanding insulation protection, which helps to reduce heating and cooling costs.
