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.

Ductwork for delivery of low temperature air

A ceiling vent diffuses air from a heating or cooling system in a laminar flow into a room for optimum dispersion in the room. Inlet air strikes a hinged vane within the vent. The vane deflects the air in a narrowing air way along a continuous concave curvature and extending all the way to the outlet opening of the vent. The vane responds to the force of air flow to narrow or enlarge the air way and, thus, regulate the velocity of air exiting the vent. A curved air catch associated with the vane directs the outflow of air and also laterally disperses air within the vent. The vent maintains a relatively constant velocity and diffusion of air into a room despite variable flow rates from the source of air.
