Quick Overview

A closed-cell polyiso foam core integrally laminated to heavy, durable and dimensionally stable inorganic coated-glass facers.

Manufactured in a tapered profile to attain positive drainage while maintaining the highest thermal efficiency available in a tapered system.

Typically specified for use in certain single-ply, BUR and modified bitumen membrane systems.

Also available in a 25-psi formula.

Available in 4’ x 4’ (1220mm x 1220mm) only.

CFC-, HCFC-, and HFC-free foam blowing technology with zero ozone depletion potential (ODP) and zero (negligible) global warming potential (GWP).

Polyiso is the highest R-value per inch insulation in the industry.

Excellent R-values reduce energy demands while maintaining compatibility with all types of roofing membranes and fire assemblies.
