An Overview of XPS and Polyiso Rigid Foam Products
Rigid Foam Insulation has come a long way in enhancing and protecting the life of a building’s roof. This is primarily due to the ever-increasing demand for greener building efficiencies, including better thermal maintenance and maximum water resistance. Both XPS and Polyiso Rigid Foam product lines are specially designed for use in Protected Roof Membrane Assemblies (PRMA). Here are some benefits of each type:
| Extruded Polystyrene (XPS) Insulation is installed directly over the roof membrane. One such product is Owen Corning’s Foamular® 604 XPS Insulation. Produced by Owen Corning’s patented HYDROVAC® process, this insulation protects the roof membrane from physical damage, thermal stress and UV exposure. The insulation also provides a stable R-value of R-5 per inch of thickness. In addition, the closed-cell content of this insulation greatly reduces the potential for water absorption.
Polyiso Rigid Foam
| Polyiso Rigid Foam Insulation consists of a polyisocyanurate core available in a variety of facers, including foil, fiber, GC, and more. Polyiso also typically provides an R-value of R-7 to R-8 per inch of thickness. Hunter PanelTM polyiso products, which are manufactured using environmentally minded practices, are available in straight, tapered, beveled, and even vented panels. Among its brands: the H-Shield line, and Cool -Vent, a specialty product. The panels are specially designed to provide high-thermal continuous insulation with proper drainage, no matter what the roof’s pitch.
