We're building in Utah along the Wasatch front. Winters are cold and snowy here, yet I've noticed that many production homes do not have insulated garages or garage doors.
Our house is a rambler style, so we won't have any rooms over the garage. The garage door faces west.
Should we insulate our garage and get an insulated garage door?
Are there any reasons that someone would choose NOT to insulate (besides not wanting to spend money on that)?
