People typically think of insulation as something that prevents cold air from getting in the house during the winter. Actually, insulation resists the flow of heat, so it’s beneficial in both winter and summer. During the cold months, insulation stops heat from pushing up and out of your house, but in the summer months its reverse, it stops attic heat from pushing down into your house. That’s a good thing too – have you felt how hot it is in an attic lately? I was in one this afternoon and trust me; it was hot – close to 140 degrees Fahrenheit in fact!
Stopping heat gains (your house getting warmer from the sun) begins with the sealing of passageways in your home that allow hot air to push into your living space. Most of these holes and penetrations are in your attic floor; typically they’re electric runs, plumbing lines and even the cut-outs for your HVAC system. Other times they’re just from poor building designs! After that’s been taken care of, add the insulation! Code for attic insulation in our area is R-49 or roughly 15-17” depending on the product type.
After the work is done, enjoy a more healthy, comfortable and efficient house. Do this right the first time, and you won’t have to worry about it for over 20 years.
