(WDEF) Your attic is for more than just storage. A properly insulated attic can reduce your energy costs by 10 to 20 percent.
Angie Hicks of Angie's List said, "If you would like to add or update insulation in your home you're going to be hiring an insulation contractor. Talk to them about what you house needs. They are going to talk to about the R value that's in your home and what's recommended for your region of the country."
Jim Vanslyke is an Insulation Contractor. He said, "R value is the resistance to heating and cooling of loss to where there is cold or heat. R is resistance so the higher the R value the more resistance to heating and or cooling. Hot or cold."
Vanslyke added, "Your heating and cooling bills drop 10, 15, 20 percent every R-5 or 10 you add. A new home is a whole lot more efficient that the old ones."
So how do you know if you have enough insulation in your attic?
Hicks said, "Insulation can deteriorate over time so it's important for you to check it periodically. A good rule of thumb is if you can see the floor joists, you don't have enough insulation."
And what kind?
Vanslyke said, "There's fiberglass and cellulose. That's basically the two. Fiberglass is white and cellulose is gray, but it's denser so we think cellulose is a little bit tighter, especially on older houses."
This year eligible homeowners can claim up to $500 in energy efficient home improvement tax credits.
