On this record cold morning of -2 degrees, with the wind chill feel of -21 in Allentown, all of us are thinking about energy efficient products to keep your home as warm as possible. A.B.E. Doors & Windows sells the Raynor Affina garage door that has one of the highest insulating values on the market, R-18. Like most consumers, this number means nothing to them when you just say it. So I decided to perform a little experiment at my home this morning to explain what it means. I have two Raynor Affina 9’w x 7’h garage doors installed on my garage at home. My garage is attached to my home, but is not heated. I took a picture on my GMC Acadia’s dash board with the car parked in the garage. The temperature read 32 degrees. After I drove 3 miles to work, the temperature read -6 degrees. So when I ask the question, “What does an R-18 insulated garage door mean to your home?” I can say it kept my garage 34 degrees warmer than the actual temperature outside!
