New Garage Doors

The most common new garage door today is the steel garage door.  They come in a variety of styles and insulation types.

The first door is called the pan door or hollow back door.  It is a steel door without insulation. These have an r-value of 0 and are usually 24 gauge or 25 gauge steel. They are the least expensive of the doors and because there is no insulation in the panels, it is the noisiest of the doors, it is kind of like a steel drum.  Steel pan garage doors look like this on the back.

The second type of door is the vinyl back door.  These doors have a polystyrene insulation (styrofoam) and have an r-value of 3-6 for most doors.  These doors are the same as the pan door counterparts with the insulation just added into the pan door. These doors are fairly quiet and provide that little bit of insulation that some customers need to keep that garage a little warmer in the winter and a little cooler in the summer. They work well in climates where it doesn’t get too hot or too cold most of the time. There is a layer of vinyl on the back of the polystyrene and the doors look like this:

The last type of door is the steel front/steel back door.  These doors have a 25 or 27 gauge steel front and back.  There is a foam core of either polystyrene or polypropylene and have an r-value of between 7-15 depending on the insulation and the thickness of the door.  These doors are great for the customer that has a workshop in the garage or is always working out in the garage and needs to have the garage at a more reasonable temperature. These doors can sometimes save you a little on your heating and cooling costs. These doors look like this:
