Abstract
A mulling system for a plurality of fenestration units includes a first joining plate configured to attach to a first outer edge of a first fenestration unit. The first joining plate includes a first outer face. The mulling system also includes a second joining plate configured to attach to a second outer edge of a second fenestration unit. The second joining plate includes a second outer face. The second joining plate is configured to engage the first joining plate to join together the first fenestration unit and the second fenestration unit with the first outer face facing the second outer face. The mulling system additionally includes a deflectable seal member attached to the first joining plate and having a sealing surface that faces away from the first outer face. The sealing surface is configured to deflect and seal against the second outer face of the second joining plate.
