• Attic Insulation

    According to the Department of Energy, heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate attic insulation and air leakage are leading causes of energy waste in most homes.Attic insulation


    • Saves you money and our nation's limited energy resources
    • Makes your house more comfortable by helping to maintain a uniform temperature throughout the house
    • Makes walls, ceilings, and floors warmer in the winter and cooler in the summer

    The amount of energy you conserve will depend on several factors: your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use. Once the energy savings have paid for the installation cost, energy conserved is money saved - and saving energy will be even more important as utility rates continue go up. The insulation experts at Mr. Attic can help ensure that you have the right insulation in your attic. We’ve been helping families in Walnut Creek, Concord, Danville, Lafayette, San Ramon, Oakland, Berkeley, Martinez, San Rafael, and Antioch save money and be more comfortable in their homes for over 10 years.

    How Insulation Works:

    Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements - wherever there is a difference in temperature.

    During the summer, heat moves from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating attics, ceiling, walls, decreases the heating or cooling needed by providing an effective resistance to the flow of heat.

    Does your home need more insulation? Unless your home was constructed with special attention to energy efficiency, adding insulation will probably reduce your utility bills significantly. Most existing homes in the United States are not insulated to the levels used today. Older homes are likely to use more energy than newer homes, leading to higher heating and air-conditioning bills.

     R - Value

    An insulation's resistance to heat flow is measured or rated in terms of its thermal resistance or R-value.  The more heat flow resistance your insulation provides the higher your "R-value" and the lower your cost will be to heat or cool your home will be.

    To determine whether you should add insulation, you first need to find out how much insulation you already have in your home and where.  If you live in a newer house, you can probably find out this information from the builder. If you live in an older house, you'll need to inspect the insulation yourself or give us a call for a free insulation evaluation.
    Determining Recommended R-Values

    Once know the R-value your existing insulation you can then use the U.S. Department of Energy's Zip Code Insulation Calculator to determine how much insulation you should add and where to achieve the recommended insulation levels for maximum energy efficiency.
