Are wood garage doors good for a very cold climate?
Wood is naturally a pretty good insulator. However, if you live in a climate where winters are harsh and very cold, wood may not be the best material for your door. The wood panels are typically not that thick and therefore do not provide much in the way of insulating value to your home. You would likely be better off with an insulated metal door or a fiberglass door which usually has insulation sandwiched in between the panels.
