Andersen offers several choices in custom designed joining materials. Whether or not to use reinforcement in a window combination is dependent on the combination size and the design load requirement. The combination size is based on the geometry and area of the combination in question. Design load is based on several factors; wind speed, location, orientation, elevation, and others. Local building codes should be consulted for determining the design load of your installation. Determination of the design load is the sole responsibility of the architect, building owner, contractor, and/or consumer. Refer to the Combination Design section in the Andersen® Product Guide for further information.

Proper joining material selection for Andersen® windows and patio doors is essential if the benefits of experienced window design and engineering, quality materials and skilled workmanship are to be fully attained.

Every assembly, joining, and installation is different. Andersen strongly recommends consultation with the local Andersen supplier or an experienced contractor, architect, or structural engineer prior to the installation of any Andersen product.

VERIFY YOUR SELECTION

• Calculate the average adjacent unit dimension ((A + B) ÷ 2).

• Determine the mullion length (C).

• Use the windload chart below to cross reference the average adjacent unit dimension with the mullion length to determine the windload performance of your combination.

• Be sure that this performance is adequate for your installation requirements.

• Refer to the Combination Design section in the Andersen ® Product Guide for further information.
