Professional Considerations

Grade 1 Insulations

Our goal is Grade 1 insulations, no matter the type of insulation, spray foam or fiberglass batt. Grade 1 is the highest rating your insulation installation can receive during building inspection. This grade fills cavities without compressions, gaps, voids or misalignments and will be on par with the manufacturer’s instructions.

Bison Insulation commits to Grade 1 installs on every project to keep the inspection process smooth. The property owner may experience comfort issues like fluctuating temperatures and have higher utility bills due to improper insulation. Bison Insulation has superintendents in the field checking installs daily to ensure our properties pass energy inspections and provide customers with the highest quality control possible.


RESNET and JobWerks

At Bison Insulation, we strive to stay at the forefront of the insulating industry. RESNET is a not-for-profit body that creates the standards for building energy efficiency rating systems. Bison Insulation was fortunate to launch the pilot of RESNET—Building America, a program for the mentoring and assessment of high quality insulation installers. The pilot program was based on a joint development effort led by Bison Insulation and RESNET. The program features practical instruction, field mentoring, and assessment of high quality insulation installers. The foundation of this program is a tablet-based program—JobWerks Insulation Installer—developed by RESNET and Organic Think. JobWerks Insulation Installer offers the promise of an educated and skilled insulation installer workforce, giving builders confidence that insulation will be installed to meet the RESNET Grade 1 Insulation Installation rating.
