Product Description

FlintBoard® ISO-T Cold Tapered Polyisocyanurate Roof Insulation 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 offered in a variety of tapered panels, providing average long-term thermal resistance (LTTR) values from 4.2 to 12.9. Higher LTTR values can be achieved with layers of flat FlintBoard ISO. 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.
