I would be very hesitant to do this. The Windows are well made but still made from thin aluminum that has the tendency to move and bow . My top window pane came loose from the inside track on one of mine as i was installing it and it was simply due to the flexing that occurred when i turned it sideways as i was climbing a ladder with it. They are designed to slide up and down vertically and I could foresee problems installing these sideways.
32" x 55" is the nominal (common) size of this window unit and the opening it will fit. The windows are manufactured an 1/8" shorter for the width. All sides also have a nailing flange that can be scored off to fit if your opening is smaller than 32x55.
These windows are not intended to be used as a prime window.
Easy install, fit perfectly.
Due to the Premium series windows not being stock sizes, you will not be able to find them on the Home Depot website. You will need to visit or call your local Home Depot store to have a store associate help you quote those windows out.
Because it is a custom size and not a standard size, it would cost more money than what the standard sizes show on the website.
We do offer mill-finish storm windows. You can visit your local Home Depot store to receive a quote.
