The rules at our house go a little something like this: I decorate the interior and my husband is in charge of the garage. He takes his garage duties very seriously and the garage is always immaculate, so I can't complain! Last weekend he decided to insulate the garage. Insulation helps keep the garage cool during summer and warm during winter. It also eliminates sound and looks nice. In a little over an hour, he completed our three car garage. I was impressed was the ease of the installation process.
