POLYISO PRODUCT BENEFITS
- Requires less embodied energy to manufacture than mineral wool
- Does not require thermal barrier because it acts as one (per IECC 2012 ASHRAE 90.1)
- Compressive strength allows polyiso to stand up to foot traffic from routine maintenance
At low temperatures competing polyiso boards require additional thickness to achieve the same R-value of Firestones polyiso.
