MONA INSULATION SERVICES – INTERWEST INSULATION

Local Connection: Mona, Utah

Mona’s lavender farms perfume the Juab Valley each June, while Mount Nebo’s 11,900-foot summit looms to the east. Daytime heat builds fast on the open benches, then night air rushes down the canyon and drops the mercury 30 degrees in a blink. Homes built during the 1990s ranch boom usually carry minimal attic batts and little air-sealing, so indoor temperatures swing as wildly as the high-desert sky.

We start every Mona project with a blower-door test, then seal top plates and can lights before blowing attics to R-49-plus. Closed-cell foam at rim-joists stops dust that drifts in from alfalfa fields, and dense-pack fiberglass hushes U.S-91 truck noise. After upgrades, residents report roughly 15 percent lower summer power bills—money that can go toward lavender honey and fall rodeo tickets instead of another A/C cycle.
