Why Attic Insulation Keeps Your House Warm in the Winter and Cool in the Summer
At first it may seem odd to add insulation for warmth and then purposely allow cold air to enter the attic through vents, but this combination is the key to a durable and energy-efficient home.
Proper insulation and air sealing keeps attics cold in winter by blocking the entry of heat and moist air from below. In the summer, natural air flow in a well-vented attic moves super-heated air out of the attic, protecting roof shingles and removing moisture. The insulation will resist heat transfer into the house.
How to check your Attic Insulation Levels
Here are the basic steps to check your insulation level.
You will need a tape measure or ruler, a flashlight and your cell phone.
Climb up your attic stairs or ladder and raise the attic hatch or door.
Stick the ruler into the insulation or with the measuring tape calculate the depth in inches. Record the number or or use or cell phone to take a photo/video.
Compare your results to the recommended R value. If you have less than 13-14 inches of insulation you are below the recommended levels and you will want to consider adding more insulation to increase your home’s energy efficiency.
