10 Good Reasons to Use Polyiso Insulation Boards for Your Commercial Buildings
Polyisocyanurate insulation boards offer many benefits that make them an advantageous solution when it comes to designing efficient assemblies. This article lists the 10 main benefits of using polyisocyanurate insulation boards for your commercial roofing projects.
1. High Thermal Efficiency
With the highest R-value per inch in the industry, based on LTTR (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, is 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.
Polyisocyanurate is compatible with most solvents used in construction adhesives.
7. Environmental Friendliness
Polyisocyanurate is a product without CFCs and HCFCs.
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.
