CertainTeed FlintBoard ISO Cold Polyisocyanurate Roof Insulation features a closed-cell polyiso core with integrally laminated heavy, coated glass facers. FlintBoard ISO Cold has been specifically engineered with a more durable facer and higher dimensional stability for use with roofing systems that utilize cold applied adhesive as the membrane bonding agent. Suitable systems include single ply, cold applied modified bitumen and cold applied BUR. DO NOT use with hot asphalt, coal tar or hot applied membranes.
CertainTeed ISO-T is offered in a variety of thicknesses, providing long-term thermal resistance (LTTR) values from 4.5 to 15.3. Higher LTTR values can be achieved with layers of flat ISO. FlintBoard ISO-T is a closed-cell, polyiso core integrally laminated to heavy, black (non-asphaltic), fiber-reinforced felt facers. FlintBoard ISO-T is also available in 25-psi formula. Available in 4' x 4' (1220mm x 1220mm) panels only.
Before installation begins, the roof deck must be firm, well attached, even, clean and dry. Do not leave exposed. FlintBoard ISO Cold is a polyiso organic plastic foam and will burn if exposed to an ignition source of sufficient heat and intensity, or open flame, such as a welder's torch. Do not apply flame directly to FlintBoard roof insulations
