As a salesman I have been asked many times what is the value of purchasing an insulated door. My response is simple. You are purchasing iron toes. You’ll a garage door for the largest opening in your home. You have living space above the garage. You have heating ducts and pipes in this garage. The R-factor of this door shouldn’t be less than 16. In addition, the proper weather seal should be applied to the exterior of your garage door. In other words you need the right door which is an insulated one, with the proper weather seal which will cut down on your heating and cooling cost.
