Best Attic Insulation Services in Lee’s Summit & the KC Metro Area

Poor attic insulation often shows up in ways you can feel or notice around the house. Common signs include:

• Uneven temperatures: Upstairs rooms are much hotter in summer or colder in winter than the rest of the home.
• Higher energy bills: If you notice higher bills with no other meaningful changes to your home’s HVAC systems, your insulation may be the culprit.
• Ice dams on the roof in winter: Warm air melts the snow on the roof and refreezes at the eaves, a common sign of attic insulation failure.
• Aging insulation: Visibly thin, settled, or compressed insulation when checking the attic.

If several of these sound familiar, a free attic check can show exactly what's going on.

The recommended R-value depends on your climate zone and home type. Here in Kansas City, we’re in Climate Zone 4 (mixed-humid). The U.S. Department of Energy recommends R-49 to R-60 for Zone 4 to achieve optimal energy efficiency and comfort.

Most of the older homes we blow insulation into have an R-value between R-19 to R-30, which is usually insufficient. If you have an older home and want to see how your R-value holds up, give us a call.

Blown-in fiberglass (like Owens Corning) is loose-fill material blown into attics to fill gaps and create a uniform layer. It’s great for retrofits because it conforms around obstacles (wiring, pipes) without compression. Compared to other types:

• Cellulose: Dense, good soundproofing, but can settle more and hold moisture.
• Spray foam: Higher R-value per inch, air-seals perfectly, but more expensive and harder to remove later.
• Batt/roll fiberglass: Easier DIY, but leaves gaps around edges and compresses over time.

Blown-in fiberglass offers excellent coverage, minimal settling, fire resistance, and cost-effective performance. It’s ideal for most attics when installed professionally.

Properly installed insulation actually improves ventilation performance by keeping the attic closer to outdoor temperatures. We always baffle soffit vents first to maintain airflow channels and avoid blocking intake vents. Owens Corning fiberglass is non-absorbent and mold-resistant, so it doesn't trap moisture when the attic is ventilated correctly. If ventilation is already poor, we flag it during assessment and recommend fixes (e.g., adding ridge/soffit vents) to prevent condensation or ice dams.
