ABSTRACT OF THE DISCLOSURE To carry conditioned air from a conditioned air source to a receiving body an apparatus, or duct system, is required. In this invention the duct that will carry the conditioned air from a conditioned air source to the receiving body will be in one continuous length. Said duct will be enclosed in insulation and together the duct and insulation are framed within a plywood box. All sides of the box are also in one continuous length. Metal, preferably steel, is wrapped around the box and fastened to the bottom of the box. This metal seals the duct system and makes it weatherproof and fireproof. The duct system will be made in varying lengths and will be capable of hooking together in series. This invention can have a dolly at either end thus making it portable, or it can be mounted onto blocks or concrete making it fixed.
