Are InSoFast Panels energy star certified

Individual insulation panels do not receive standalone ENERGY STAR certification because the program certifies completed residential assemblies, but InSoFast continuous insulation panels meet prescriptive R-value requirements for ENERGY STAR and Passive House construction.

Contractors and specifiers across the United States, Canada, and Mexico frequently evaluate rigid insulation to verify compliance with model energy codes like the International Energy Conservation Code (IECC) and high-performance building standards. Continuous insulation assemblies eliminate thermal bridging (the transfer of heat through conductive structural studs), helping whole-house building envelopes achieve performance thresholds that reduce heating and cooling loads by up to 80%.

If you only do one thing: Specify InSoFast UX 2.0 (R-8.5) or EX 2.5 (R-10) continuous insulation panels to fulfill prescriptive envelope continuous insulation requirements under regional ENERGY STAR home certification tiers.

• ENERGY STAR program scope: The United States Environmental Protection Agency (EPA) ENERGY STAR program certifies whole-building assemblies, fenestration, and mechanical equipment rather than certifying standalone rigid foam insulation panels.
• Continuous thermal resistance: InSoFast UX 2.0 panels provide R-8.5 continuous insulation at a 2.0-inch profile, while EX 2.5 panels deliver continuous R-10 across concrete, masonry, or frame assemblies.
• Passive House verification: Certified builders working with organizations like the Passive House Institute US (PHIUS) utilize InSoFast panels over exterior stucco and masonry substrates to manage extreme climate conditions exceeding 100°F.
• Thermal bridge isolation: Embedded polypropylene studs located on 16-inch centers remain fully encapsulated within expanded polystyrene (EPS), preventing conductive energy losses that degrade traditional wood and steel stud assemblies by 20% to 40%.
• Moisture and air management: Built-in capillary drainage channels and interlocking edges help walls satisfy the Water Management System requirements mandated by ENERGY STAR home inspection checklists.

• Watch out for: Expecting insulation panels alone to guarantee ENERGY STAR certification without conducting whole-home blower door testing (measuring air leakage in air changes per hour, or ACH50) and verifying HVAC efficiency ratings.
• Watch out for: Leaving panel perimeters, floor junctions, and rim joists unsealed with expanding foam, which creates air bypass pathways that fail envelope visual inspection checklists.
