Will insulating my attic make my house warmer?
One of the places in your home where a little bit of attention can make a big difference in your comfort — and heating bill — is the attic. According to the Department of Energy, properly insulating the attic can save 10 to 50 percent on a typical heating bill.
How important is attic insulation?
Insulating your attic can help prevent air from escaping the house and stop outside air from coming in. Heating and cooling costs account for up to 50-70 percent of the energy used in an average home. This means that losing your home’s hot or cold air makes for a huge energy waste.
Does insulation in attic help keep house cool?
Yes. Attic insulation helps keep you cool in the summer.
Why do people put insulation in their attics for the winter?
Well, attics are some of the biggest sources of energy loss in homes. Heat rises, and it can leak out of your home if your attic isn’t well insulated. Attic insulation traps heat that would otherwise escape. Thermal, rather than foil, insulation materials are used for this purpose—such as fiberglass or cellulose.
How do I stop my attic from getting hot?
4 Ways to Reduce Attic Heat in Your Home
- Seal spaces around plumbing, recessed lights and vents. Your attic can get as hot as 150 degrees in the summer.
- Install adequate insulation. Start by examining the insulation that is already in your attic.
- Install gable vents.
- Get an attic fan, and have it serviced regularly.
Why do attic rooms get so hot?
The laws of thermodynamics dictate that heat naturally rises, which means your attic is the last stop for hot and warm air in your house. Your attic also rests right under your roof, which means on hot summer days the heat is going to radiate through the shingles and collect in your attic, creating a lot of hot air.
How do I keep my attic cool in the summer?
Best Way to Cool an Attic

Why is my attic cold in the summer?
Many attics contain ductwork that supplies cool air to upstairs rooms during the summer and heated air during the winter. If the joints in your ductwork are not properly sealed, your forced air system can suck attic air into the ducts –air that’s either really hot in the summer or really cold in the winter.
How much does insulating an attic cost?

How can I keep my attic cool in the summer?

How do you add insulation to an attic?
To add insulation to the attic floor, you will require enough blanket material to do the job, a heavy-duty shop vacuum, plastic sheeting for covering the blanket material that will insulate the attic opening, a heavy-duty staple gun, and utility scissors with long blades. You will also need a strong board to kneel on that will span the joists.
What is the recommended insulation depth for an attic?
In temperate coastal areas such as Zone 3, attic insulation of at least R30 up to a maximum of R60 is recommended. For loose-fill cellulose, this translates to a total depth ranging from 8 inches up to 16 inches.

Adding insulation to your attic not only saves you money, it saves energy as well.
How much insulation do I Need?
