Energy-Efficient Insulation Solutions for Bay Area Homes

Where Your Energy Bills Actually Go

In most Bay Area homes, heating and cooling account for the largest share of monthly energy costs, and a significant portion of that energy is lost through inadequate attic and wall insulation. When conditioned air escapes through the building envelope, your HVAC system works harder, runs longer, and costs more to operate. Proper insulation addresses the source of the problem, not just the symptom.


Yorkshire Roofing installs attic insulation systems designed for Northern California's climate that reduce thermal transfer and improve indoor comfort year-round.

Attic Insulation Installation and Upgrade

The attic is one of the easiest places to add insulation to improve the comfort and energy efficiency of your home. Owens Corning AttiCat Expanding Blown-In Insulation is designed for your attic insulation project in new or existing homes. This is an unbonded loose-fill fiberglass insulation designed for use exclusively with the AttiCat® machine.


Features of Pink Blown-in Insulation:

  • Can cover the entire attic in as little as 2 hours (based on a 1,000 sq. ft. attic up to R-30, blowing time only)
  • Helps achieve the right R-value for your climate zone
  • Provides complete coverage, even around HVAC ducts, pipes, wires, and outlets
  • Available in R-values ranging from 19 to 60
  • Ideal for DIY homeowners looking to upgrade attic insulation quickly and efficiently

Measurable Energy Savings

Properly installed insulation can reduce heating and cooling costs by up to 30%. In practical terms, that means:



  • More consistent indoor temperatures without continuous HVAC cycling
  • Reduced strain on heating and cooling equipment, extending system lifespan
  • Lower monthly utility costs, beginning immediately after installation
  • Potential qualification for utility rebates and energy efficiency incentive programs
  • Increased home value through documented energy performance improvement
