Abstract
The invention provides a pre-insulated duct having a length and comprising a tube having a foam layer. The pre-insulated duct has an interior face and an exterior face and a thickness defined as a distance between the interior face and the exterior face. The interior face of the pre-insulated duct bounds an airflow space. In the present group of embodiments, the pre-insulated duct has a mounting rail system extending along the length of the pre-insulated duct. The mounting rail system includes at least one mounting rail, and preferably a plurality of mounting rails, positioned on (e.g., positioned on an exterior of) the pre-insulated duct.
Claims32
A pre-insulated duct having a length extending along a longitudinal axis such that the pre-insulated duct forms a lumen having an airflow direction extending along the longitudinal axis, the pre-insulated duct comprising a tube having a foam layer, the pre-insulated duct having an interior face and an exterior face and a thickness defined as a distance between the interior face and the exterior face, the interior face of the pre-insulated duct bounding an airflow space of the lumen, the pre-insulated duct comprising four sides and having two opposed open ends, the two opposed open ends being centered on the longitudinal axis, the pre-insulated duct having a mounting rail system extending along the length of the pre-insulated duct, the mounting rail system comprising mounting rails that are positioned on only two of the four sides of the pre-insulated duct, and wherein on each of the two sides on which the mounting rails are positioned there is only a single mounting rail line extending along the length of the pre-insulated duct, each of the mounting rails having a length and being elongated in the airflow direction such that the length of each of the mounting rails is substantially parallel to the longitudinal axis.
A pre-insulated duct having a length and comprising a tube having a foam layer, the pre-insulated duct having an interior face and an exterior face and a thickness defined as a distance between the interior face and the exterior face, the interior face of the pre-insulated duct bounding an airflow space, the pre-insulated duct having a mounting rail system extending along the length of the pre-insulated duct, the mounting rail system comprising a plurality of mounting rails that are positioned on exterior sides of the pre-insulated duct, the pre-insulated duct including a plurality of internal braces that are located in the airflow space and that are spaced-apart from one another along the length of the pre-insulated duct, each of the mounting rails being attached to the plurality of internal braces at locations spaced-apart along the length of the pre-insulated duct, each of the internal braces comprising first and second rods that are crosswise to each other, wherein the first and second rods do not extend through the foam layer but rather each of the mounting rails is attached to the plurality of internal braces by a plurality of traversal linkage pins that each extend through the thickness of the pre-insulated duct so as to project through the foam layer.
