EP ComfortCore™
Choose the exterior insulation package that best fits your home, wall assembly, and performance goals. EP ThermoShield™ is our continuous exterior insulation system designed to reduce thermal bridging, improve wall performance, and add a stronger insulation layer to the outside of the home.
As you move up through the ThermoShield™ packages, you gain more insulation thickness, stronger thermal break performance, and a more complete exterior wall upgrade.
Most homeowners looking for the best mix of exterior insulation value, wall performance, and overall efficiency choose EP ThermoShield™ Elite.

Frequently Asked Questions
Frequently Asked Questions — Insulation
Michigan code recommends R-49, though many older homes have R-19 or less. We recommend R-49 minimum and up to R-60+ for maximum comfort and savings in our harsh winters.
Start with the attic—heat rises, so it's where you lose the most energy (up to 30%). Wall insulation is valuable in older homes with little or no insulation. We use thermal imaging to prioritize improvements.
Most attic projects finish in one day. Spray foam may take 1–2 days. Premier whole-home packages involving walls, crawlspaces, and rim joists take 2–4 days.
Possibly—federal tax credits up to $1,200 annually are available through the Inflation Reduction Act, and some Michigan utilities offer rebates. Ask about current eligibility during your consultation.
Every installation includes our EP Protection Plan™ lifetime workmanship warranty. Material warranties range from standard coverage (blown-in) to lifetime (Premier packages).
