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.Installation
Before installation begins, the roof deck must be firm, well attached, even, clean and dry.
