Upstairs we have an equipment room which has two exterior walls and celiling which is not insulated. The floor and two walls are insulated. I heard that you cannot insulate an entire exterior room with out an air vent. They said that in the winter, cold will be trapped in and in the summer, heat will be trapped in. He is in the process of installing barrier on the ceiling of that room. What is your opinion on this. I don’t want to spend the money and go through the trouble if it will not do any good.
