Through the Attic — Largest Single Heat Loss Pathway in Isabella County
An attic with R-11 to R-19 — common in pre-1990 Isabella County homes versus Zone 5 R-38 minimum — continuously conducts heat upward into the cold attic and out through the roof. Blown cellulose from Energy Plus brings Mt. Pleasant attics to R-38 or R-49 in a single day. Energy Star average 15 percent reduction. Consumers Energy rebates up to 400 dollars. Federal 25C tax credit up to 1,200 dollars per year.
Through Single-Pane Windows
Every single-pane window in your Mt. Pleasant home has an R-value of approximately R-1. The wall beside it is R-13 to R-19. Each square foot of single glass loses heat 13 to 19 times faster than the surrounding insulated wall — all winter, continuously. EP VueSeries replacements bring window R-value to R-3 to R-5. Federal 25C tax credit up to 600 dollars per year.
From the Crawl Space Through the Stack Effect
An unencapsulated crawl space connects your Mt. Pleasant living areas directly to outdoor air. Cold rises from below into first-floor rooms through the stack effect, forcing continuous furnace operation. Spray foam encapsulation stops this pathway permanently. Federal 25C tax credit up to 1,200 dollars per year.
Through Air Bypasses at Ceiling Penetrations
Every pipe, wire, and duct through your ceiling into the attic reduces insulation effectiveness 30 to 40 percent regardless of R-value. Energy Plus includes air sealing at all penetrations as standard with every attic insulation project in Isabella County.
