Polyisocyanurate insulation boards offer many benefits that make them an advantageous solution when it comes to achieving high thermal efficiency in your commercial roofing projects. But, the benefits go beyond that. Here are the top reasons roofers across Canada are gravitating to this exception and reliable product.

1. High Thermal Efficiency

With the highest R-value per inch in the industry, based on long-term thermal resistance, polyisocyanurate is the most effective thermal insulation product on the market.

2. Excellent Dimensional Stability

When used in a roofing system, the insulation retains its original dimensions, which prevents the formation of thermal bridges that could reduce the building's energy efficiency. In the case of wall systems, because polyisocyanurate is rigid, it will not collapse. It also won’t deteriorate or lose its thermal performance during the building’s service life.

3. Exceptional Service Temperature

The service temperature is between the lowest and highest temperatures that a product can stand without losing its physical characteristics. Polyisocyanurate’s service temperature is -73 to 122 °C (-100 to 250 °F), which makes it possible to apply the product with hot bitumen.

4. Convenient Size

It is lightweight, easy to transport and handle, and has constant thickness.

5. Fire Resistance

Polyisocyanurate meets the criteria of ASTM E84 Standard and shows superior performance in fire tests.

6. Compatibility

Polyisocyanurate is compatible with most solvents used in construction adhesives.

7. Environmental Friendliness

Polyisocyanurate is a product without CFCs and HCFCs.

8. Versatility

Polyisocyanurate can be used to insulate both roofs and walls.

9. LEED Credits

Polyisocyanurate panels can help in obtaining numerous LEED credits.

10. Meets the Requirements of Building Codes

Polyisocyanurate is still the only foam plastic insulation product to have both FM 4450 and CAN/ULC-S126 approvals when installed directly on a steel deck. Both tests are specifically referenced in many building codes.
