According to the Harvard University School of Public Health, if your home is as little as 5 to 10 years old, you likely have one of the 46 million under-insulated homes in the US.
Worse Yet, If your insulation has not been inspected in over three years it very well could have compressed itself enough to reduce your R-values by half – This means much higher energy bills.
Most Homeowners Think That Simply Rolling More Fiberglass Is The Answer, THEY ARE WRONG… And Its Costing Them Thousands.
Pink rolled fiberglass leaves your joists and rafters exposed and it has been proven, by the Oakridge National Laboratory, that exposed structural lumber is a key source of heat loss.
Even more important is that Insulation which is compressed will not give you its full rated R-value. This happens a lot because many people make the mistake of adding denser insulation on top of lighter insulation in an attic. Installing more insulation over existing insulation is a process known as "capping."
Rolling Out More Fiberglass Simply Will Not Work… PERIOD.
Researchers at Oak Ridge National Laboratories found that "capping" fiberglass insulation with more fiberglass "fails to restore the lost R-value"
Unfortunately, that is what most homeowners do. You know, the “do-it-your-selfer” who rushes out to the nearest home improvement warehouse and buys the thickest insulation they can find. They take it home and then just throw it on top of what’s already in their attic; or worse, they shove batts rated for one thickness into a thinner cavity wall that it’s not designed for.
Bottom Line: the only real way to raise the insulation value in your attic is to use blown insulation. It covers all the nooks and crannies, goes where fiberglass can’t, and can easily cover exposed wood beams (exposed timber) which is a major source of heat loss. Blown insulation will even raise the insulation value of any existing fiberglass insulation you may have. No other insulation on the market today can do that.
