Welcome to R30 Insulation!
Because of the recent down turn in the economy, many people are combining two causes: going green and saving money. While many of us think of going green as being more expensive, when it comes to saving energy, the two go hand in hand.
The best way to save energy in your home is to make sure it is well insulated. If you live in a home more than about 20 years old, ask a professional to come in and determine whether your home is properly insulated. This could cut your energy bills by up to 50%. If you live in a warm, southern climate, proper insulation will allow you to run the air conditioner less while maintaining a comfortable temperature in the summer. Homes in cold weather climates will keep more heat in the house, reducing heating bills.
Insulation comes in various sizes and R factors. The greater the R factor, the more efficient the insulation is and the more energy you’ll be saving. Experts recommend the insulation in the attic or ceiling of the top floor of a home have an R factor of at least 30.
R30 Thickness can vary depending on the specific need of the individual. Traditional insulation is a rolled mat of fiberglass that is unrolled between the rafters of a home. R30 insulation is about 9 inches inches thick and comes in widths from 16 inches to 24 inches wide. The widths allow it to fit between most standard joists. Rolled insulation is usually preferred by builders when constructing a new home.
Blown insulation is becoming a more popular choice these days, especially for retro fitting an older home. Though some use blown fiberglass, that is falling out of favor because it is itchy and doesn’t tend to retain its R value. Other products like blown cellulose do not have these negatives and provide excellent temperature control in the home. Blown fiberglass needs to be about 13 inches thick to have an R30 factor, while cellulose needs only an 8 inch thickness to achieve the same insulation factor. Cellulose is made largely from old newspapers, so it is a green choice as well.
Rolled Fiberglass Insulation Prices vary. Most will cost you about $.50 to a $1.00 per square foot, plus installation. Blown cellulose insulation costs about $2.00 to $3.00 a square foot, which includes professional installation.
