When it comes to selecting the best overall insulation product for commercial roof systems, polyiso is the product of choice. No other foam insulation has the perfect combination of features so important for long-term performance. These performance features provide excellent initial installation costs as well as attractive life cycle payback rates.
Polyiso insulation is the only foam insulation that can be used in almost all types of roof systems without the need for a thermal barrier. Polyiso’s high-temperature stability prevents melting when mopped with hot bitumen. Polyiso is unaffected by properly applied construction adhesives, and many membrane manufacturers specify its use without the need for a cover board in single-ply adhered systems.
