CertainTeed FlintBoard® ISO-T Cold Tapered Polyisocyanurate Roof Insulation is a rigid, board insulation specifically for roof membranes applied using cold adhesive, in a tapered design to promote proper roof drainage. Not for use with hot applied roofing materials.
FlintBoard ISO-T Cold is manufactured in a tapered profile to offer the combination of high thermal value plus promotion of proper roof drainage. As with regular FlintBoard ISO Cold, FlintBoard ISO-T Cold features closed-cell polyiso core with integrally laminated heavy, coated glass facers. In multi-layer roof system applications, FlintBoard ISO-T Cold is installed over one layer of FlintBoard ISO in accordance with CertainTeed specifications.
FlintBoard ISO-T Cold is a recommended roof insulation for use in conjunction with CertainTeed Commercial Roofing Systems including Flintlastic® Roof Systems which utilize SBS modified bitumen adhesive as the membrane bonding agent.
FlintBoard ISO-T Cold is offered in a variety of tapered panels, providing average long-term thermal resistance (LTTR) values from 4.5 to 15.3. Higher LTTR values can be achieved with layers of flat FlintBoard ISO. Available in 4' x 4' panels only.
