R38 Insulation Upgrade with Blown In Fiberglass Insulation After Whole House Fan Installation in Fresno, CA

Jeff contacted us because we had installed a whole house fan for him but as it was getting closer to summer, he wanted to upgrade his insulation. We had informed him that his insulation was low when we installed the whole house fan in January, but he wanted to upgrade his insulation at a later date. When we initially inspected his attic, we observed that his insulation was low — only about 4 inches. He knew from our previous visit that upgrading his insulation would keep the cool air in his house longer and reduce his dependency on his air conditioner during the summer.

We began the insulation upgrade by sealing off visible holes, gaps, and cracks. This helps to prevent air from flowing between his attic and the living spaces of his home. Next, we blew in premium, fiberglass insulation up to an R38 level, or 14 inches. 

As a result of the insulation upgrade, Jeff and his family will enjoy a cooler, more comfortable home during summers, a warmer home during winters, and reduced heating and cooling costs for the life of their home.
