Frame and Dividers

Openings tab in model data under External Glazing, Internal Glazing and Roof Glazing headers

Frames are applied to all rectangular windows (default and custom) but not to other shaped windows and not when using the Fill surface (100%) facade type.

If the glazing does not have a frame or dividers, uncheck the Has a frame? box. If Has a frame? is checked and then you can enter:

• The construction of the frame and dividers,
• The number of horizontal dividers and vertical dividers,
• Frame width and divider with (see diagrams below for definition).

External Windows on walls

For external windows on walls the following dimensions in the direction of the glazing normal can also be entered:

• Outside reveal depth
• Inside reveal depth
• Inside sill depth
• Outside divider projection
• Inside divider projection
• Outside frame projection
• Inside frame projection
• Divider glass edge-centre conduction ratio
• Frame glass edge-centre conduction ratio
• Divider type

The definition of the above dimensions is shown in the diagrams.

Dividers

The schematics below show how DesignBuilder divider data is used to describe real glazing systems.

Note: If you do not wish to model the shading/reflection effect of the reveal/frame/divider then simply set the projection/depth to zero.
