Abstract
A ventilation duct includes an envelope lined on the inside by insulation panels. The panels have a lining on the side of the flow channel of the duct and on at least one part of at least one of transverse edges of the duct. This lining extends over at least one part of each of both sides of the edge and is integrated with the panel. Z shaped sections may be used to hold adjacent panels.
Claims6
A ventilation duct comprising:
- an envelope;
- at least one insulation panel lining an interior of said envelope, thereby forming a circulation chamber in which a gas can flow in a flow direction;
- and
- at least one lining integrated with the at least one insulation panel and positioned on at least one part of at least one edge of the at least one insulation panel, this edge extending in a direction transverse to the flow direction and being placed at the side of the circulation chamber, and positioned on at least a part of each of both sides of the at least one insulation panel adjacent the at least one edge.
1 more element
An insulation panel used for internal lining of a ventilation duct, comprising:
- a panel body formed of an insulating material;
- and
- at least one lining integrated with the body panel and positioned on at least one part of at least one edge of said panel body and on at least a part of each of both sides of the panel body adjacent the at least one edge, the at least one edge extending in a direction transverse to a flow direction within the ventilation duct and placed at a side adjacent a flow in the ventilation duct.
