Cause 1 — Attic Insulation Below Zone 5 R-38 Minimum
Zone 5 requires R-38 in the attic. Most Isabella County homes built before 1990 have R-11 to R-19. That gap costs 15 to 20 percent of your Consumers Energy bill every month through the heating season. Energy Plus blown cellulose brings most Mt. Pleasant attics to R-38 or R-49 in a single day. Energy Star average 15 percent reduction in heating and cooling costs. Consumers Energy rebates up to 400 dollars. Federal 25C tax credit up to 1,200 dollars per year.
Cause 2 — Single-Pane or Failed Double-Pane Windows in Isabella County
Single-pane aluminum windows have an effective R-value of approximately R-1. The wall beside them is R-13 to R-19. Every square foot of single glass in your Mt. Pleasant home loses heat 13 to 19 times faster than the surrounding wall — all winter, continuously. EP VueSeries replacements bring window R-value to R-3 to R-5. EPA estimated savings for Zone 5 Isabella County: 100 to 600 dollars per year.
Cause 3 — Unencapsulated Crawl Space Below the Home
An open crawl space connects your living areas directly to outdoor temperatures through the stack effect. Cold air rises continuously into first-floor rooms making them perpetually cold and forcing your furnace to compensate constantly. Closed-cell spray foam encapsulation plus a vapor barrier stops this pathway permanently. Federal 25C tax credit up to 1,200 dollars per year.
Cause 4 — Air Bypasses at Ceiling Penetrations
Every pipe, wire, and duct through your ceiling into the attic is a potential bypass for warm air. Dozens of unsealed bypasses in a typical Isabella County home reduce 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.
