Duct panel
A duct panel, a method of manufacturing a duct panel, a duct section and a method of installing a duct are disclosed. The duct panel includes a laminate structure having an insulation layer disposed between a first support layer and a second support layer, the laminate structure having an end width; and an end cap attached to the end width and configured to be coupled to a mounting flange, wherein the mounting flange is configured to mount the duct panel. The end cap and the mounting flange comprise different materials.
1. A duct panel comprising:
a laminate structure having an insulation layer disposed between a first support layer and a second support layer, the laminate structure having an end width; and
an end cap attached to the end width and configured to be coupled to a mounting flange, wherein the mounting flange is configured to mount the duct panel,
wherein the end cap comprises a plastic material and the mounting flange comprises a metal, and
wherein the mounting flange and the second support layer form a unitary construction.
2. The duct panel as claimed in claim 1 , wherein the insulation layer comprises polyisocyanurate (PIR).
3. The duct panel as claimed in claim 1 , wherein the plastic material is polyvinyl chloride (PVC).
4. The duct panel as claimed in claim 1 , wherein the first support layer is configured to form an internal surface of a duct, the first support layer comprising a material selected from a group consisting of galvanised steel, aluminium and stainless steel.
5. The duct panel as claimed in claim 4 , wherein the second support layer is configured to form an external surface of the duct, the second support layer comprising a material selected from a group consisting of galvanised steel, aluminium and stainless steel.
6. The duct panel as claimed in claim 5 , wherein the mounting flange extends outwardly relative to the second support layer.
7. The duct panel as claimed in claim 1 , wherein the end cap comprises a locking member, wherein the locking member is configured to engage with a corresponding locking member of the mounting flange.
8. A duct section comprising a plurality of duct panels as claimed in claim 1 , the duct panels forming an enclosed cross-section.
9. The duct section as claimed in claim 8 , wherein adjacent duct panels are attached to each other along a length-wise direction of each panel using a locking mechanism.
10. A method of installing a duct, the method comprising:
assembling a plurality of duct panels as claimed in claim 1 to form a duct section; and
mounting the duct section to at least one adjacent duct section using the respective mounting flanges.
11. A method of manufacturing a duct panel, the method comprising the steps of:
disposing an insulation layer between a first support layer and a second support layer to form a laminate structure, the laminate structure having an end width;
attaching an end cap to the end width; and
coupling a mounting flange to the end cap,
wherein the end cap is made of a plastic material and the mounting flange is made of a metal, and
wherein the mounting flange and the second support layer form a unitary construction.
12. The method as claimed in claim 11 , wherein the insulation layer is made of polyisocyanurate (PIR).
13. The method as claimed in claim 11 , wherein the plastic material is polyvinyl chloride (PVC).
14. The method as claimed in claim 11 , wherein the first support layer is made of a material selected from a group consisting of galvanised steel, aluminium and stainless steel.
15. The method as claimed in claim 11 , wherein the second support layer is made of a material selected from a group consisting of galvanised steel, aluminium and stainless steel.
