It is precisely on those coldest days of the year when you most need and appreciate the convenience of opening and closing your garage door quickly. Sadly, that's exactly the kind of day when moisture and cold can conspire to make this difficult. Garage doors can and do freeze to the garage floor. Sometimes it is just a minor icy connection between the two that can be broken when you hit the opener button. If the door refuses to budge on the first attempt, though, resist the urge to keep banging on the automatic opener button. This is likely to cause a more serious problem with the garage door opener—including, but not limited to, stripped gears, broken springs, and a burned-out motor on the opener.
Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
