IKOTHERM Polyisocyanurate TEST RESULTS IKOTherm is a rigid, polyisocyanurate foam insulation with high thermal properties. It is constructed from a closed cell polyisocyanurate foam core that is bonded on each side to fiber-reinforced facers during the manufacturing process. IKOTherm is designed to be part of a modified bitumen, built-up or single-ply roof system. IKOTherm insulation is dimensionally stable and can be sized with ease. It is also lightweight and easy to handle. Its high R-value thermal resistance provides outstanding insulation protection, which helps to reduce energy costs. IKOTherm is available in standard 1220 mm x 2440 mm (4’ x 8’) or 1220 mm x 1220 mm (4’ x 4’) sizes. IKOTherm Tapered is available in 1220 mm x 1220 mm (4’ x 4’) size. The top surface of IKOTherm Tapered is manufactured with a slope of 1/16”, 1/8”, 3/16”, 1/4” or 1/2” per foot to provide for positive roof drainage. Cost-effective. C ompatible with all types of roofing systems. • Dimensionally stable. • Excellent compressive strength. • Excellent thermal R-value. • Excellent performance in fire tests. • igh-temperature resistance for hot H mopping applications. • pproved for direct installation on the roof A deck without a thermal barrier (CAN/ULC S126M compliance). • eets U.S. (ASTM C1289) and Canadian M (CAN/ULC S704) product standards. • ISO 9001:2008 Registered Facilities. • • Evaluated by Canadian Construction Materials Centre under CCMC listing #13037-L BUR & Modified Bitumen Systems IKOTherm is applied by fastening each panel to the roof deck with Factory Mutual approved fasteners (appropriate to the deck type) and plates. IKOTherm panels of up to a maximum 1220 mm x 1220 mm (4’ x 4’) may be adhered to a suitably prepared concrete roof deck and vapor barrier with a full mopping of hot Type II or Type III asphalt or approved cold adhesive. The edges of the board must butt up against each other and the joints of adjacent panels must be staggered. IKO, NRCA and the CRCA recommend the installation of an overlayment board prior to the application of built-up roofing, such as 3 mm (1/8”) IKO Protectoboard. For best roof system performance, an overlayment board should be installed under the roof membrane. The roof covering can then be installed according to the membrane manufacturer’s specifications.

Above IKOTherm test results were produced according to CAN/ULC S704, and ASTM C1289. Note: IKOTherm not to be used on exposed or inverted roofs. THERMAL VALUES Thickness* IKOTherm panels are loosely laid on the roof deck. The edges of the board must butt up against each other and the joints of adjacent panels must be staggered. The roof covering can then be installed according to the membrane manufacturer’s specifications. Fully Adhered Single-Ply System Ballasted Single-Ply Systems IKOTherm panels are securely fastened to the roof deck with Factory Mutual approved fasteners (appropriate to the deck type) and plates. IKOTherm panels of up to 1220 mm x 1220 mm (4’ x 4’) may also be adhered to a suitably prepared concrete roof deck and vapor barrier with a full mopping of hot Type II or Type III asphalt. The edges of the board must butt up against each other and the joints of adjacent panels must be staggered. * Additional thicknesses available upon request. ** Typical Values.1 The long term thermal resistance (LTTR) values of IKOTherm Roof Insulation were determined in accordance with CAN/ULC S704 using CAN/ULC S770. These values can be used as design R-Values that more closely represent the anticipated thermal performance over the life of isocyanurate foam insulation products. Note: The IKOTherm product is produced to “inch” thicknesses, so the R-values shown should be regarded as more accurate than the RSI values, which have been calculated from the rounded mm equivalents.
