Your Home Insulation Experts
How do you know if you have enough insulation in your attic or exterior walls? Which type of insulation should you use? Will adding more insulation lower my heating and cooling bills?
The U.S. Department of Energy states that adequate home insulation, as recommended for your geographical area (see below), can save you up to 30 percent on home energy bills. Most homes are under insulated.
A comprehensive Free Home Insulation Estimate and Inspection from Dr. Energy Saver will sow you how much insulation your house has and how much you may need for your home to be properly insulated.

Insulation really works
A roll of fiberglass insulation or a handful of cellulose insulation may not look like much, but these materials make a big difference in how your home retains heat during the winter and cool air during the summer. Think of how long soup stays hot when you store it in an insulated thermos. That's how your home's insulation can work for you. Proper insulation is just as important for energy savings during hot weather as it is in the wintertime. A Dr. Energy Saver technician can show you how well insulated your home is with a thermal imaging camera.
If you're undecided about adding more insulation now, think of how you'll feel when fuel prices shoot up again. No matter how you heat and cool your home, the same rule applies: energy upgrades pay for themselves faster as energy costs go up.
Insulation is rated in terms of R-value per inch,
so multiplying the material's R-value per inch
by the thickness will give you total R value.
What "R" you talking about?
All insulation is tested to determine how well it resists transferring heat. That's what the "R" in insulation's R-value stands for: resistance to heat flow. The higher the R-value, the higher the resistance and greater the insulating value. When talking about insulation, R-value is typically expressed in two ways:
- Overall or total R-value. This number is used as a measure of the total insulation value. It's also used to describe the insulation value of a complete building structure, such as a wall that would include studs, plywood sheathing, siding, insulation and drywall.
- R-value per inch. Insulation is manufactured from different insulating materials and in different thicknesses. Manufacturers rate their products in terms of R-value per inch, so multiplying the material's R-value per inch by the thickness will give you....
What kind of insulation, and how much?
Based on Dr. Energy Saver's findings, we will recommend
insulation upgrades in critical areas of your home.
There are quite a few different types of insulation materials, including fiberglass batt, cellulose, rigid foam board, and spray foam insulation; and each type has particular characteristics that make it suitable for some applications and less desirable for others. In terms of total R-value targets for your house, the general rule of thumb for insulation is: The colder your climate, the more insulation you need. Dr. Energy Saver will show you how the current levels of insulation in your house compare with insulation levels recommended by Energy Star and the U.S. Dept. of Energy (see the map).

What the U.S. Dept. of Energy Says about Adding Insulation to a Home
Unless your home was specially constructed for energy efficiency, you can usually reduce your energy bills by adding more insulation states the U.S. DOE. Many older homes have less insulation than homes built today, but adding insulation to a newer home may also pay for itself within a few years.
