GRANTSVILLE INSULATION SERVICES – INTERWEST INSULATION

Local Connection: Grantsville, Utah

Grantsville sits on the edge of the Deseret Peak Wilderness, where summer rodeos echo against 11,000-foot ridgelines and desert evenings cool fast under clear stars. Many ranch homes were framed quickly during early-2000s growth and never upgraded beyond code-minimum attic fill. 

We top those attics to R-49, seal knee-wall voids common in bonus rooms, and wrap garage ceilings so bedrooms above stay livable after noon sun bakes the west façade. Closed-cell foam at rim-joists keeps desert dust off stored tack, while owners report 12–15 percent lower year-round energy costs—money better spent on Bit-n-Spur tickets than space heaters.
