a wide variety of combination designs.

Combination Types

Ribbons Determining Design Wind Load Performance

Ribbons are horizontal window combinations (vertical joins) where opposite ends Proper combination design in conformance with local wind load requirements is
(head and sill) of individual windows are fastened to the building structure. vital to the success of your project. To make sure a combination is safe and that it
complies with local building codes, the combination design wind load performance
Stacks
capacity must be determined.
Stacks are vertical window combinations (horizontal joins) where opposite sides
Correctly determining this performance capacity involves the following three steps:
(both side jambs) of individual windows are fastened to the building structure.

Two basic configurations are used in combination designs:
STEP 1
1-way configurations or 2-way configurations.
Determine Building Code Requirement
1-Way
Make sure that you have the proper local codes and have identified specified
compliance values. This calculated value (PSF) will be used to determine if the
combination will be ac cept able (STEP 3).

STEP 2
Ribbon Combination Stack Combination
Determine Product Performance
Compare product Design Pressure Rating data to the local building code (PSF)
2-Way
requirement. This will show whether the individual units in a com bi na tion design
are acceptable.

STEP 3

Multiple Ribbon/Stack Combination
Determine Combination Performance
2-way combinations exist when multiple vertical stacks and horizontal ribbons This step helps determine whether a given product, size, configuration and joining
are joined together. Unlike 1-way combinations, the adjacent sides (head and material type will meet the local building code design wind load requirement. To
