Attic Insulation

One of the least expensive ways to improve your home’s energy efficiency is by adding more insulation to your attic.  Attic Insulation may not seem like a big deal, but it can have a significant impact on your energy bill and it will only cost a fraction of what you’ll pay to install energy efficient windows and siding.

Heat Rises (Winter) During cold winters, we spend big bucks trying to keep our houses a comfortable temperature. But heat rises, and very few homes are designed to be airtight. That means that a significant amount of the hot air you blow into your home is going up and seeping into your unprotected attic. There, it cools from the uninsulated environment, and falls back downstairs, forcing more hot air up. It’s a vicious cycle that leeches the heat from your house. Some estimates say that 25% of energy is lost through this process.

Heat Rises (Summer) Not only is lacking attic insulation bad during the winter, attic insulation also plays a key role during the summer. Attics can get unbearably hot during the summer months, even reaching as high as 150 degrees. This heat warms the entire structure of your house, which is why your ceilings and upper level often feel so warm. The heat from the attic, now being pumped into the home, makes your air conditioner work harder to cool your house, increasing your energy bill and increasing wear on your air conditioner. It’s even worse if your conditioned air is pumped through your attic, as all that heat saps the cool air from the ducts. This could lead to heat blowing from your vents.

Heat Radiates Having a hot attic and little insulation between it and you means that, on a hot day, your top floor’s ceiling becomes a boiler plate. The problem is that building materials like wood soak up heat readily, and then radiate it back. With no insulation to keep your ceiling’s timbers from heating up, they will get nice and toasty. That heat will, in turn, radiate down into your home, countering much of your cooling effort and further wasting money.

Considering that attic insulation is relatively inexpensive, there’s little money to be lost and lots to be gained from insulating your attic.

Nearly 25% of energy loss occurs through the attic of peoples’ homes. In order to make your home as energy efficient as possible, the Department of Energy recommends insulation level of R-49 in the state of Illinois.

The Owens Corning loose fill fiberglass is an insulation solution that is superior to both cellulose and expanding foam insulation. Our Atticat blowing machine conditions the pink fiberglass by breaking it up and fluffing it, adding millions of the tiny air pockets that give the material its insulating power. The pink fiberglass will not settle and it will keep its energy-saving R-value over time. Call Now for a FREE Attic Inspection & SAVE energy with Cornerstone Exteriors!
Benefits of blown-in insulation

• Save up to 20% on energy bills (average homeowners are overpaying $400-$500 annually on utility bills)
• Reduce heat gain/loss in the winter/summer (Insulation will create a comfortable and healthy environment for the family)
• Extend the life of your roof (Heat rises up and slips through your ceiling and into your attic. The heat contained in your attic will push up against your shingles, causing it to lose granules and eventually brittle)
• Reduce greenhouse gas emissions
• Helps prevent mold and mildew (Excessive heat will allow moisture build-up inside your attic causing health problems disguised as mold and mildew)
• Helps reduce airborne noises
