Window Type Properties

To modify a type property of a window, you change the value of the corresponding parameter as described under Modifying Type Properties.

Note: Changing a window type property will affect all windows of that type in the project. Note also that the type name does not update when you change type parameter values. For example, you could use the type parameter Structure to change the width of the Generic - 6” wall type to 6.5”, but the type name will remain Generic - 6”. If you want to create a new window type, click Duplicate. For more information, see Creating a New Family Type in a Project.

Common type properties for windows are described below.

Name	Description
Construction
Wall Closure	This parameter sets the layer wrapping around the window. It overrides any settings in the host.
Construction Type	The type of construction for the window.
Materials and Finishes
Glass Pane Material	The material for the glass panes in the window.
Sash Material	The material for the window sash.
Dimensions
Height	The height of the opening of the window.
Default Sill Height	The height of the bottom of the window above the level.
Width	The width of the window.
Window Inset	The inset of the window into the wall.
Rough Height	The height of the rough opening for the window. Can be scheduled or exported.
Rough Width	The width of the rough opening for the window. Can be scheduled or exported.
Identity Data
Assembly code	Uniformat assembly code selected from hierarchical list.
Keynote	Add or edit the window keynote. Click in the value box to open the Keynotes dialog. See Keynotes.
Model	The model number of the window.
Manufacturer	The manufacturer of the window.
Type Comments	Specific comments about the window type.

Description	A specific description of the window type.
Assembly Description	Description of the assembly based on the assembly code selection.
Type Mark	A specific value to designate the particular window. This value must be unique for each window in a project. Revit warns you if the number is already used, but allows you to continue using it. (You can see the warning using the Review Warnings tool. See Reviewing Warning Messages.) Values are assigned sequentially. See Creating Sequential Door or Window Tags.
Cost	Cost of the window.
OmniClass Number	The number from Table 23 of the OmniClass Construction Classification System that best categorizes the family type.
OmniClass Title	The name from Table 23 of the OmniClass Construction Classification System that best categorizes the family type.
IFC Parameters
Operation	The operation of the window, as defined by the current IFC description (for example, single_panel or triple_panel_horizontal). These values are case-insensitive, and underscores are optional. (SINGLE_PANEL and SinglePanel are the same.)
Analytical Properties
Analytic Construction
Heat Transfer Coefficient (U)	Used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid.
