Hey Tim,
I want to replace my old wood windows with all vinyl new construction windows. I'm going to rip off my aluminum siding, remove and replace the old windows, and install vinyl siding. I'd like to use new construction windows because they have the nailing flange and siding channel. My problem is that my walls are about 5 1/8" thick and the closest thickness of window I can find is the standard 4 9/16". Does any company custom make vinyl windows with a custom jamb depth? Are there such things as vinyl extension jambs? Can I use wood extension jambs with vinyl windows? I really don't want to use replacement windows. My walls are - 3 1/2 stud, 3/4 sheathing, and about 13/16 sheetrock.
Thanks,
Ian K.

Ian,
It is doubtful you will find vinyl windows the size you need. The reason is simple. The vinyl extrusions that are used to create the jambs and sills are made to precise sizes. The cost for the dies to make these extrusions is in the hundreds of thousands of dollars. It would be insanity for a company to make all sorts of different sizes hoping people might order them from time to time.
All you need to do is make a slight modification inside with clear wood trim to create your own extension jambs. Just paint the wood on all sides and edges before installing it and make sure you use a paint that matches in color and sheen that is hopefully an identical match to the vinyl.
