  • How does the system work?

    1. Radiant barrier spray and radiant barrier foil  improve energy efficiency by keeping the sun’s heat from entering your attic.  Lowering the temperature in your attic with a radiant barrier reduces the stress on your heating and cooling system, allowing it to work less, thus saving you money.  We offer both a spray on product which is cost effective and can be more easily applied in tight areas, and a foil radiant barrier which blocks more radiant heat from entering your attic, but requires a greater investment.  Visit our radiant barrier page to learn about  each type so you can choose the radiant barrier that best fits your needs.

    2. Attic insulation performs a critical role in energy efficiency by slowing down the transfer of heat from your attic into your living space.  Hiring Mills to install the Department of Energy’s recommended 18″-22″ of attic insulation will slow down extreme attic temperatures before they enter your living space, keeping the inside of your house cooler in the summer and warmer in the winter.  The bottom line is that a well insulated attic equals lower energy bills and a more comfortable living environment.  Attic Insulation also has superb sound absorption abilities, so properly insulating your attic will keep the inside of your home comfortable and quiet.

    3. Balanced attic ventilation is necessary to remove damaging moisture from your attic.  Moisture builds up in the attic from normal activities conducted in home, such as cooking and showering.  If this moisture isn’t removed with attic ventilation it can lead to mold and mildew problems, and cause the roof decking to rot. This moisture also hurts energy efficiency by making insulation damp. Adding the recommended amount of vents along eave and rooftop will keep the attic cool and dry, and is far less expensive than replacing your entire roof in a few years.

  • Attic Insulation Information

    Increasing attic insulation is the most effective way to increase the energy efficiency of your home. Attic insulation eases the strain on your heating and cooling system; thereby reducing energy costs and improving comfort.

    Attic insulation makes it much easier for your heating and air conditioning system to keep your home cool in the summer and warm in the winter.  Attic insulation does this by trapping inert air and creating a temperature-neutral pocket between areas of opposing temperature. This trapped pocket of air doesn’t allow heat to transfer from the warmer area to the cooler area so that, in the summer, the air cooled by your AC unit stays colder longer. All this adds up to running your air conditioner less and less – extending its life and using less energy, saving you even more money.

    The most common types of home insulation are blown fiberglassblown cellulosefiberglass batt or fiberglass blanket. Blown fiberglass insulation is the best type of attic insulation, providing the highest level of energy efficiency as well as a bevy of other benefits.  Blown fiberglass is not dusty so it won’t hurt your eyes or lungs. It’s naturally flame retardant so it greatly reduces the risk of attic fire.  It has low chemical content so it won’t damage your sheetrock or joists, and it never settles, maintaining a consistent, high R-value for as long as it’s in your attic.

    R-value is a measurement of the effectiveness of home insulation. The higher the R-value, the less heat will pass through your attic insulation. To illustrate how insulation reduces cost, imagine  the temperature in your attic is 140 degrees. But you’re running the air conditioning to keep the inside temperature at 75 degrees.  An average home has 3 to 4 inches of old insulation, with an R-value of 6. That level of insulation allows 5200 btu to come through your ceiling every hour. An average, 2000 sq ft home with an normal air conditioning system (3.5 ton, SEER 11) can generate around 48,000 btu/hour. This means your AC must work 11% harder every hour just to keep your home at constant temperature, let alone actually lower the temperature. When your poorly-insulated attic is fighting against your AC all summer, that 11% will cost you thousands and thousands of dollars in just a few years.

    With an R-value of around 2.5 per inch, a proper amount of blown fiberglass insulation drastically reduces heat transfer and your AC unit can easily keep a constant, comfortable temperature. The Department of Energy’s  recommended level of attic insulation for most regions in the US is an R-value between R38 and R60, which is between 15 and 22 inches of blown fiberglass insulation.

  • Radiant Barrier Information

    A radiant barrier is a highly reflective material applied to the underside of your roof that is designed to reduce summer heat gain and winter heat loss in your home.

    A radiant barrier works in concert with attic insulation and balanced ventilation to keep your home comfortable and your energy bills in check.  The two most common types are radiant barrier spray, also called radiant barrier paint, and radiant barrier foil.  Mills uses only the best radiant barrier paints that are tested and certified to block the most heat.  We are proud to install the new and improved Sherwin Williams radiant barrier as well as HeatBloc Ultra and Radiance.  Foil radiant barrier reflects more heat but is difficult to install in tight spaces or in attics that are already well insulated.  Radiant barrier spray helps this problem because it is somewhat easier to apply, especially in tight attics because it is applied with special equipment that helps in hard to reach areas.  Because of the relative ease of application, radiant barrier paint is often more cost-effective than the foil type heat barrier.  Whichever type you choose to install, our radiant barrier installers will apply it correctly so you realize the maximum benefit from the product.  Choose your radiant barrier company wisely as some contractors will cut corners to save money.  There are even reports of contractors watering down their radiant barrier paint to “stretch” the material further.  This is something Mills would never allow.

    More on the properties of radiant barriers:

    When the sun heats a roof, it’s primarily the sun’s radiant energy that makes the roof hot. A large portion of this heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.

    Performance is determined by three factors:

    • Emissivity (or emittance) - the ratio of the radiant energy (heat) leaving (being emitted by) a surface to that of a black body at the same temperature and with the same area. It’s expressed as a number a between 0 and 1. The higher the number, the greater the emitted radiation.
    • Reflectivity (or reflectance) - a measure of how much radiant heat is reflected by a material. It’s also expressed as a number between 0 and 1 (sometimes, it is given as a percentage between 0 and 100%). The higher the number, the greater the reflectivity.
    • The angle the incident radiation strikes the surface-a right angle (perpendicular) usually works best.

    All radiant barriers must have a low emissivity (0.1 or less) and high reflectivity (0.9 or more). From one brand to another, the reflectivity and emissivity are usually so similar that it makes little difference as far as thermal performance. (Most products have emissivities of 0.03-0.05, which generally corresponds to a reflectivity of 95%-97%.) Also, the greater the temperature difference between the sides of the radiant barrier material, the greater the benefits it can offer.

    Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. They can lower cooling costs between 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system.
