Insulation

The most basic, cost-effective way to lower your home's energy usage and improve the comfort level of your home

Insulation Heat flows naturally from a warm place to a cooler space. In the winter, heated air will try to flow to an unheated garage, basement or attic. Conversely, in warm months, heat will try to flow from the outdoors into the cool interior of the home. The majority of this heat transfer in homes takes place in the attic.

It's the role of insulation to prevent this unwanted circulation throughout your home. Combined with proper ventilation and a radiant barrier, proper insulation helps your home maintain a comfortable, uniform temperature throughout the year with significantly less use of heating and cooling systems. As a bonus, insulation can also act as a sound absorber, to help make your home quieter.

Frequently Asked Questions
What is the benefit of insulation?

+

Heating and cooling systems consume 50% to 70% of the energy used in the average American home. You will save on your energy costs if you reduce the amount of energy needed for heating and cooling. Insulation helps your home retain heat in cold weather and reject heat in warm seasons.
Doesn't my house already have insulation?

+

It probably does not have enough. In much of the housing in America, attic insulation levels are inadequate at best. That's because many homebuilders only offer standard (not optimal) levels of attic insulation, in order to maintain competitive selling prices. Obviously, the older the home, the less likely it is to have adequate attic insulation. But even in a newer home, additional attic insulation will save enough money in reduced utility bills to pay for itself, and those savings will, of course, continue year afeter year. Upgraded attic insulation will also increase the value of your house.
How does insulation work?

+

Heat flows naturally from a warmer to a cooler space. In cold weather, it flows from heated rooms to the unheated attic, garage or basement, or to the outdoors. In hot weather, heat flows from outside your home to its interior. To maintain comfort, 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. Insulation resists the flow of heat, preventing unwanted circulation. Thus, in a well-insulated house, rooms stay warmer in winter, cooler in summer, with less energy expenditure.
What is R-value?

+

The R-value rating refers to the insulations thermal resistance - its ability to resist heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and density. Installing more insulation in your home increases the total R-value and the resistance to heat flow.
