Chris writes from San Antonio, Texas: "I am building a new house in San Antonio. Coming from the Midwest, I am wondering if I should insulate the exterior garage wall. The house will be 4 sides brick."

Answer: We recommend insulating the wall that is connected to the house. If the garage is not going to be used as a conditioned space, insulating the rest of the walls is not recommended. Faced insulation should be used with the insulation installed so the facing is toward the house.
