Insulation

Everyone knows that home insulation provides tremendous energy savings, but most homeowners have questions about it. How do you know if you need more insulation? What can you do to improve it—without tearing your home apart?

The first thing to know is that for homes built before the 1970s, insulation was not a high priority in construction. These homes may benefit from adding insulation as well as filling the window and door gaps that naturally occur as the house settles over time. The good news is it’s easy to improve your home’s energy efficiency, no matter what its age.

Fill the Spaces in the Walls

For your walls, you can choose to blow loose insulation directly into the wall. It’s fast and you’ll only have to patch the wall afterwards, rather than replace the entire surface. On the other hand, if you’re remodeling, you may have open walls and an opportunity to choose from many insulation options including blankets, rolls, rigid insulation and others.

Go Beyond the Walls

Many homeowners see savings from insulating electrical outlets, crawlspaces and doors. A rule of thumb is: a 1/8″ space between a standard exterior door and the threshold is equivalent to a two square inch hole in the wall. Realigning your doors and replacing the door sweep are easy fixes.

Consider Replacing Windows

Weather-stripping your windows can reduce energy loss. However, up to 50% of a home’s heating and cooling needs results from heat gain and loss through windows, so actually replacing your old windows may provide the most savings.

Insulation Adds Up to Big Savings

When you insulate, not only do you start saving money on your energy bills, the government also provides financial benefits to homeowners who make their home more energy efficient. Be sure to save your receipts.

Improvements like adding insulation can often add to the resale value: potential buyers will want to know all about them. And even if you’re not quite ready to move yet, you can still enjoy a cost savings and a comfortable home.
