Window Systems


2200 Folding Window Series 

As folding doors become more and more popular, some of our customers have asked us if we'd be willing to make a few windows to match their doors. Our response? "Sure, why not."
Today we use the same proven platform to make our hybrid folding windows as we do for our hybrid folding doors. And unlike other manufacturers who solely use aluminum, vinyl or wood when manufacturing their folding window systems, Win-Dor combines both vinyl and aluminum to offer our customers something truly unique.
