Polyiso can be used on the roof and the walls. In commercial buildings, insulation and a cavity wall of air space provide protection from weather and fire, as well as continuous insulation across a wall. In residential construction, polyiso sheathing insulation is used to insulate the entire wall (including the framing, which accounts for at least 20% of the total wall area and often is uninsulated), thereby significantly reducing heat loss through both convection and conduction.

Polyiso’s many attributes include:

• Highest R-value per inch of thickness
• Moisture resistant, water repellent panel
• Resistant to solvents used in construction adhesives
• Excellent dimensional stability
• Superior performance in fire tests — polyiso meets the strict standard of both FM Class Approvals 1 UL 1256/ULC S126
• Service temperature range from -75 F (-60 C) to +225 F (+107 C) to reflect Canadian and US material standards
• Long Term R-value (only roof insulation with third party certification)
• Recycled content
• Zero ozone depletion potential
• Virtually no global warming potential
• Nationwide availability
