Abstract
An insulated air duct apparatus including insulated duct modules and associated insulated fitting apparatus for transferring a volume of fluid in a warm air heating and air conditioning installation without employing external insulation or structural support members, otherwise required to support and insulate duct apparatus including a plurality of lightweight duct modules in combination with take-off connectors for joining such modules, each duct module comprising duct walls joined by corner members wherein said duct walls and take-off connectors comprise rigid fibrous glass (RFGB) with reinforced facing having inherent structural strength such that each duct module is self supporting.
Claims7
An insulated air duct apparatus for transferring a volume of fluid in said duct apparatus without employing external insulation or structural support members, otherwise required to support and insulate such a duct apparatus, comprising:
- a) a plurality of at least two insulated lightweight duct modules each duct module comprising duct walls comprising a plurality of at least four duct panels joined by corner connectors wherein said duct panels comprise an internal insulation layer comprising rigid fibrous glass sandwiched between an inner and an outer reinforced moisture proof facing sheet having inherent structural strength such that each duct module is self supporting;
- b) access means for providing access to interior spaces of said duct panel comprising an insulated access door associated with a duct wall of said air duct module and comprising two parts, one part female having a flange, one part male having a flange whereby;
- i) said female part would be mounted on the inner surface of a duct wall by attaching a surface of said flange to an inner facing sheet of the duct wall;
- and
- ii) said male part would be mounted on the outer surface of a duct wall by attaching a surface of said flange to an outer facing sheet of the duct wall;
- c) transition means provided for permitting fluid to communicate between air duct system components comprising insulated take-off apparatus wherein said take off apparatus associates with said duct wall and comprises two parts, one part female having a flange, one part male having a flange whereby;
- i) said female part would be mounted on the inner surface of said duct wall by attaching a surface of the flange for contacting the inner facing sheet of the duct wall;
- and
- ii) said male part would be mounted on the outer surface of said duct wall with by attaching a surface of the flange for contacting the outer facing sheet of the duct wall thereby connecting the air duct modules to component members for in situ coupling of pre insulated air duct apparatus components together with pre-insulated take-off connectors.
