Save On Energy Costs with This Home Improvement

With the leaves falling and winter weather knocking on our doors, there is no better time to start preparing the house for what will probably be a very expensive winter if your house isn’t insulated.

I’ve been in the attics of thousands of homes in this area and I can tell you that 75 percent of them aren’t insulated the way they should be. Insulation acts as a barrier, helping to keep warm air inside the house by slowing the flow and stopping the heat from getting outside. The problem is that most homes, especially older ones, do not have enough insulation to keep up with our cold winters. In fact, many homes around here have barely enough insulation to withstand the cold months in Florida. 

So, how do you know if you have proper insulation? You’ll need to find out where you currently have (or don’t have) insulation, what type of insulation is installed, and what its “R-value” is. The R-value is the materials’ resistance to heat flow, so the higher the R-value, the greater the insulating properties. Once you have this information, you can determine how much additional insulation you need, which will be dependent on our Connecticut climate, your house size, and what kind of heating you have. This analysis can either be done by a qualified contractor or you can do it yourself if you’re comfortable working in the attic.

Once you determine what you need, there are two popular ways to get insulation into your home. A licensed contractor can either blow loose fiberglass under the floor in the attic or batts can be laid between the floor joists. There are pros and cons to each option and they depend on the size of the house, the clearance space, and what the attic is used for. I install insulation both ways and one is just as effective as the other - the best method is the one that works for your home.

The bottom line? The United States Environment Protection Agency says that with proper insulation, the average home in our area can save approximately 16 percent in total heating and cooling costs. For older homes, that number skyrockets to nearly 50 percent. What’s even better is that insulation almost always recoups its value when a house hits the real estate market.

So is it worth taking a look at insulation? If you like keeping more dollars in your wallet, I’d say yes.
