Abstract
A duct device for insulated delivery of temperature controlled air. The device comprises an elongated, tubular member configured as a conduit for delivery of air and having a tubular wall fabricated of non-load-bearing insulative material. This insulated material includes at least one continuous gap formed into the tubular wall and extending along the tubular member. This gap is filled with a rigid binder which bonds to the insulative material and is capable of reinforcing the structural strength of the tubular member. This binder filled gap operates as a strut, which may be positioned longitudinally along the tubular member, or in other patterns such as a helical configuration. Reinforcing structure is also disclosed for the end sections of the tubular member, along with interconnecting structure.
