Boosting Energy Efficiency with R38 Blown-In Fiberglass Insulation in Clovis, CA

Brent reached out to us from Clovis because his home wasn’t staying comfortable—especially during those long Central Valley summers. His HVAC system was working overtime, yet the house remained warm and his utility bills were steadily climbing. When we inspected his attic, we discovered only 4 inches of old cellulose insulation, which had settled and lost most of its effectiveness.

To bring his home up to today’s energy efficiency standards, we performed an R38 insulation upgrade. We added 14 inches of premium blown-in fiberglass insulation directly over the existing cellulose. This method increases thermal resistance, significantly improves indoor temperature control, and helps reduce the strain on heating and cooling systems.

By bringing his attic insulation up to the Energy Star recommended R38 level, Brent will now experience better temperature consistency throughout his home, lower energy bills, and greater year-round comfort.
