Attic Insulation Home / Attic Insulation       Does Your Attic Insulation Measure Up? · Take a tape measure into your attic and measure the depth of your existing insulation. · A little known fact is that most homes are built with the minimum required insulation by local building codes. Even new homes don't have an optimal level of insulation. When energy was cheap, home insulation was less of a concern. The older your home, the higher potential for dramatic energy loss exists. · As you can see by the map and chart below, the Dallas area is in Zone 3  we recommend a minimum of R-38 for the attic to provide appropriate, energy-saving insulation levels for your home. If you have less than 14 inches of insulation in your attic (14"=R-38), it is safe to say you are spending more money on energy than you should. If you don't measure up, contact us for a free quote at (214) 742-7252. R-Value Recommendations: · The Dallas area is in insulation Zone 3 · We recommend a minimum of R-38 for attics · R-38 equals approximately 14" of insulation The measure of resistance to heat flow. Insulation materials have tiny pockets of trapped air. These pockets resist the transfer of heat through material. The ability of insulation to slow the transfer of heat is measured in R-values. The higher the R-value, the better the insulation material's ability to resist the flow of heat through it. How Insulation Works: It Resists Heat Flow To maintain comfort in your home, 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 ceilings, walls, and floors decreases this heat flow by providing an effective resistance to the flow of heat. Heat flows naturally from a warmer to a cooler space. In winter, heat flow moves directly from heated living spaces to adjacent unheated attics, garages, and basements, or to the outdoors; or indirectly through interior ceilings, walls, and floors – wherever there is a difference in temperature. During the cooling season, heat flows from outdoors to the house interior. Most Common Types of Attic Insulation Fiber Glass Fiber glass loose-fill insulation is an extremely effective insulating material because its fibers prevent air movement and the resulting heat loss to resist the flow of heat and cold. It is designed for use in attics and hard-to-reach locations such as corners, nooks and crannies. It is installed dry, and because it will not settle over time, maintains its full R- value over the life of the home. Fiber glass loose-fill insulation is fed into a pneumatic blowing machine and blown under high pressure through a long flexible hose into the attics and walls. Although homeowners can rent blowing machines, it is typical practice to have blown in insulation installed by a professional. Rock and Slag Wool Rock wool (or slag wool) loose-fill insulation is similar to fiberglass except that it is spun from blast furnace slag (the layer of impurities that forms on the surface of molten metal) and other rock-like materials instead of molten glass. The production of rock wool uses by- products that would otherwise be put in a landfill. Rock wool insulation is well suited for locations where it is difficult to install other types of insulation, such as irregularly shaped areas, around obstructions (such as plumbing stacks), and in hard-to-reach places. Blown-in loose fill insulations are particularly useful for retrofit situations because, except for the holes that are sometimes drilled for installations, they are one of the few materials that can be installed without disturbing existing finishes. Rock wool is installed dry, and because it will not settle over time, maintains its full R-value over the life of the home. Cellulose Cellulose is made from ground-up newspapers. It is treated with fire retardants, some of which have been known to cause corrosion of wiring and pipes. The product settles significantly over time and must be over-installed to compensate for this settling. All loose-fill insulations are required to detail their installed and settled thickness on the bag label to let consumers know the expected settled R-value. Cellulose is applied using a mechanical blowing machine. In an attic, cellulose is not typically installed above an R-30 because its weight can cause sagging of the drywall. Most energy codes now call for R-38 to R-49 in attics. Sala Air Conditioning has been serving the DFW area since 1972, providing commercial and residential heating and air conditioning.

Jet Stream 73.3's unique platinum color identities it as the high performing product that you require. Application Knauf JET STREAM 73.3 Fiber Glass Blowing Insulation is typically installed in open attics of both new and existing structures. It can also be used in retrofit closed-cavity applications such as exterior sidewalls or floored attics. Loose-fill blowing insulation is intended for use where pneumatically installed insulation is most cost-effective. Features and Benefits Installation •Blows fast and smooth. •Clean, white, professional-looking appearance. •Processes better than a bag a minute. Permanence •Noncombustible, non-corrosive. •Will not rot, mildew, or deteriorate. Thermal Performance Knauf JET STREAM 73.3 Fiber Glass Blowing Insulation provides you a choice of R-values based on the installed thickness and the installed weight per square foot. The tables below show the minimum requirements for obtaining the desired R-value. The stated thermal resistance (R-value) is provided by installing in accordance with the manufacturer's instructions, the required number of bags per 1,000 sq. ft. of net area, at not less than the labeled minimum thickness. Jet Stream 73.3's new 32 pound bag gives you coverage of 73.3 square feet at R-30. Failure to install both the required number of bags and at least the minimum thickness will result in lower insulation R-values.
