Polyisocyanurate insulation has been the roof insulation of choice for the majority of commercial roofing professionals for many years. IKOTherm® and IKOTherm III polyisocyanurate roof insulations offer one of the highest thermal insulating R-value per inch thickness of all commercially available rigid board insulations. Both are available in a range of thicknesses and board sizes to meet the specified thermal needs and code requirements for a wide range of roof designs. Available in standard kraft facer, IKOTherm polyisocyanurate foam insulation is produced according to the requirements of CAN/ULC S‑704 for Type 2, Class 3 materials and ASTM C1289 Type II, Class 1, Grade 2. For added moisture resistance and surface strength, IKOTherm III uses the same polyiso core, but is faced on both sides with fiberglass mats. Both standard IKOTherm and IKOTherm III are FM and UL-approved. Strong and durable, IKO’s polyiso thermal insulation adds to the R-value of the IKO Innovi TPO single-ply roofing system, offers excellent compressive strength and performs well in fire tests.
