Wind load requirements are a product performance rating. The term "wind load" refers specifically to the structural test pressure (i.e. design pressure) a window or patio door unit can withstand. The rating for wind load is expressed within the Performance Grade (PG) rating. For more information on PG ratings, please view Performance Grade and Air Infiltrations for Andersen® Products.
For specific performance ratings of Andersen® products, please see our Performance Grade and Air Infiltrations for Andersen® Products documents (organized by product line) available on the Andersen website
