How Does Good Attic Insulation Help with Heating?

Friday, December 5th, 2014 at 11:39 am

Alright, so you’ve just installed a brand new home heating system. The ducts are pristine, the heater is running as smoothly as can be, and everything seems perfect. However, for some awful reason, you’re still experiencing cold spots in the house and your heating bill is through the roof. What’s going on? Interestingly enough, your heating might actually be going through the roof. Read on to find out how attic insulation affects your heating.

The Importance of Attic Insulation

There’s no way to completely seal your home to prevent heat from escaping. As soon as your heater stops working, the house will begin to cool from the outside in. What you can do, however, is slow down heat loss as much as possible. This will take some of the load off of your heater, which will save you money in the long run. Attic insulation is the single biggest step you can take to preventing excessive home heat loss.

Though heat can escape from multiple different areas of your home, the attic is the single most vulnerable area. There are a number of reasons for this. First, the attic is often a very large space, more or less an entire extra floor in most homes. Second, warm air naturally rises. When using a forced air system, all of that hot air that is meant to heat your home will tend to rise through the house and into the attic. If your attic is not insulated, you’re losing a great deal of that warm air at fast rate.

Once you’ve insulated your attic, you will have essentially put a lid over your house to keep all that warmth inside. Your home will lose heat much more slowly, your heater will be able to turn off sooner after starting, and your heating bill will drop. In fact, the US Department of Energy estimates that you can save between 10 and 50 percent of your heating bill by properly insulating your attic. That’s more than enough savings for the insulation to pay for itself.
