Abstract
An air duct diffuser is shown for attachment to a ceiling grid. The diffuser includes a frame which mounts to the ceiling grid and a louvre which mounts to the frame for directing diffused air within an associated air space. A pre-formed, composite housing of insulating material mounts to the frame and has punch-out duct openings of varying sizes provided therein.
Claims7
An air duct diffuser for attachment to a ceiling which can be used for diffusing air from an air duct located in the ceiling, the air duct diffuser comprising:
- a metal frame which mounts to a support structure of the ceiling;
- a louvre which mounts to the metal frame for diffusingly directing air from the air duct;
- a preformed, composite housing of insulating material which mounts to the metal frame, the housing having a duct opening provided therein to closely receive the air duct;
- wherein the performed, composite housing is comprised of fiberglass duct board;
- wherein the fiberglass duct board is preformed in a shape which is complimentary to the metal frame for receiving the metal frame and forming a backing therefor;
- and
- wherein the fiberglass duct board has an inner side which receives the metal frame and an outer side, the outer side being covered with a metal foil vapor barrier.
An air duct diffuser for attachment to a ceiling which can be used for diffusing air from air ducts of different sizes located in the ceiling, the air duct diffuser comprising:
- a metal frame which mounts to a support structure of the ceiling;
- a louvre which mounts to the metal frame for diffusingly directing air from the air duct;
- a preformed, composite housing of fiberglass duct board which mounts to the metal frame, the fiberglass duct board being preformed in a shape which is complimentary to the metal frame with an inner side for receiving the metal frame and forming a backing therefor and with an outer side, the outer side being covered with a metal foil vapor barrier, the duct board of the preformed, composite housing having a plurality of concentric score lines formed therein which define weakened, punch-out areas, each area being sized to receive a selected one of a plurality of common sized air ducts whereby a selected air duct can be connected to the frame for directing air to the louvre for diffusing air from the louvre into a space located below the louvre;
- wherein the louvre is mounted on a pair of spacer bars within the metal frame, at least one of the spacer bars having a release mechanism which allows the louvre to pivot downwardly within the frame to allow access to the interior of the frame.
A method of assembling an air duct diffuser of the type which is connected to an air duct of a ceiling, the method comprising the steps of:
- providing a frame which is mountable within an existing support structure of the ceiling, the frame having an inner side and an outer side;
- backing the frame with a preformed, composite housing of insulating material, the housing having a plurality of concentric score lines formed therein which define weakened, punch-out areas, each area being sized to receive a selected one of a plurality of common sized air ducts for mounting a selected duct to the housing and, in turn, to the frame;
- mounting a louvre to the frame by suspending the louvre from at least two spacer bars located within the frame;
- and
- wherein the composite housing is comprised of fiberglass duct board which is preformed in a shape which is complimentary to the metal frame for receiving the metal frame and forming a backing therefor, the fiberglass duct board having an inner side which receives the metal frame and an outer side, the outer side being covered with a metal foil vapor barrier.
