Insulation Upgrade to R38 with Premium, Blown In Fiberglass in 2150 Sq. Ft. House in Coarsegold, CA

Donald contacted us looking for a solution to his high cooling costs and a home that felt hot and stuffy. Although his home was built in 2005, when we inspected his attic, we found that Donald’s attic had only about 5 inches of insulation present and was bare in many spots. In addition, another company had installed a gable fan for him but had not properly blocked off the gable vent, rendering the fan useless. We determined that an insulation upgrade and blocking off the vent around the gable fan would best help Donald achieve his goals of reducing his cooling costs and making his home more comfortable.

We began by blocking off the gable vent around the fan, ensuring it could properly ventilate the attic’s heat. We then air-sealed visible leakage points with closed-cell foam, helping to mitigate the air flow between the attic and the living spaces of the home. Lastly, we blew in premium, fiberglass insulation to an R38 level, bringing the attic to the Energy Star-recommended level.

As a result of the work we performed, Donald and his family will enjoy a cool, comfortable home during the summer, a warmer home in winter, and reduced heating and cooling costs by up to 30% for as long as they live in the home.
