Why do I need Insulation?
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.
How much Insulation Do I Need?
The U.S. Department of Energy (DOE) recommends insulation levels based on a variety of factors, including the cost of energy in various parts of the country. The DOE divides the United States into six zones, and lists different R-values for each zone -- Garland is in zone 3 and requires a R-49 in the attic.
What kind of Insulation should I get?
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.
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.
