Air duct insulation layers are responsible for retaining the energy of the air within the ducts. To minimize the temperature drop of the treated air from the source to the end user, different insulation materials are used depending on the specific application.
At this stage, the insulation of air ducts is not yet shown.
At this stage, the insulation of air ducts is not yet shown.
From this stage onward, insulation is shown. In addition, measures are taken to prevent the spread of smoke and fire, in accordance with DIN EN 15501-2 and 3—Special Components.

Model representation
Features
The following characteristics are defined in this phase:
- Geometry of Fire-Rated Cladding
- Loads
- Definition of the fire resistance class
Labeling
The following fire resistance ratings can be specified for the component: EI90, EI45, etc.
Instructions
Installation of the insulation:
After selecting the air duct, the button for creating the insulation is located in the Modify | Air Ducts tab.
Depending on the requirements, the insulation can be installed inside or outside the air duct.
For more information, see the Autodesk Revit Help article "Adding Exterior and Interior Insulation to Ducts."
The type of exterior insulation and its thickness can be specified according to requirements.
In this phase, the plans and models of the insulation remain unchanged from those created during the design phase.
Presentation
In this phase, the plans and models of the insulation remain unchanged from those created during the design phase.
Features
The following characteristics are defined in this phase:
- Adjustment of the geometry of the fire-resistant linings in accordance with the duct network calculation
- Adjustment of the geometry of the duct insulation
Labeling
The labeling of the insulation layer or cladding on the floor plan should include the following fire safety requirements:
- Fire resistance class
- Insulation thickness
Instructions
Generally, the insulation—including the material, thickness, etc.—is described in more detail in the bid specifications.
