Hi all, a few questions for those more knowledgable than I about these things:

I have a Pella casement that I want to split apart and put one on each side of a fixed panel to make up a 3 window unit to make something like this:

                                                  Left swing casement || Fixed Panel || Righ swing casement

Does anyone know where I can pick up some of the alluminum ~ 3/8″ U-channel that joins the alluminum exterior of the windows together (like they are before spliting)?

And does Pella make extra nailing flanges?

Thanks in advance!
