What does Dade County require for the approval of combination window “systems”, (Mullions)?
Each of the windows to be used in the combination needs to first have Product Control Approval. Mullions, when pined on either end, as required in the code, will need to have a component approval. The County will accept rational analysis on this mullion where a combination using said mullion would be requested for tested. This single PA202 structural portion only test, will verify the rational analysis submitted. The mulled unit shall not be tested before submittal for product approval of the mullion. This supersedes question 96 in this document.
