From the lakeside breezes that sweep through Miller Beach to Crown Point’s historic Courthouse Square, Northwest Indiana experiences a humid continental climate that keeps indoor comfort top of mind.
Average relative humidity hovers north of 70% most months, so heat sneaks in during steamy summers and escapes during frigid lake-effect winters. The quality of your insulation determines how well your house resists that constant push and pull, and insulation performance is measured by R-value.
As the region’s leading insulation specialists, IBP Momper Insulation is here to demystify R-value and show you how the right choice safeguards your energy bills and your family’s comfort.
What Is Insulation R-Value?
R-value is a numerical score that indicates how effectively a material slows heat flow. Higher numbers equal stronger thermal resistance, meaning fewer BTUs sneak through your attic, walls or crawl space. Because climates differ, the International Energy Conservation Code assigns target R-value ranges by zone; Northwest Indiana sits in Climate Zone 5, so our recommended levels skew higher than milder parts of the country.
R-value also changes by location inside your house: the attic needs thicker coverage than interior walls, and basement walls require a different range than a vented crawl space. Choosing materials with the proper rating for each area keeps your HVAC equipment from working overtime and reduces condensation risk in our damp environment.
How to Calculate the R-Value
Manufacturers state the R-value per inch of every insulation product: fiberglass batts may be R-3.2 per inch, while closed-cell spray foam can exceed R-6. To reach a target level, simply multiply the per-inch rating by the planned thickness. For example:
Material R per inch Planned thickness Total R
Fiberglass batt 3.2 15 inches R-48
Closed-cell foam 6.5 8 inches R-52
When combining layers, say, cellulose blown over existing batts, add the totals together. Always confirm cavity depth, account for compressed areas around wiring or ductwork and remember that gaps dramatically reduce real-world performance. An energy pro can verify final R-values with infrared imaging and blower-door testing.
What’s the Best Insulation R-Value for My Northwest Indiana Home?
Energy Star and the 2021 IECC prescribe these targets for Climate Zone 5 homes like yours:
- Attic or roof deck: R-49 to R-60
- Exterior above-grade walls: R-13 to R-21 (or R-13 plus continuous sheathing)
- Floors over unheated areas: R-25 to R-30
Shoot for the upper end of each range if your house sits near open farmland in Lowell or Valparaiso where winds are stronger or if you want maximum utility savings.
