My house is built with Metal Window frames.
I want to put 2 Double Hung Windows side by side in the same opening.
I can order a Vinyl piece to slide between the 2 windows.
My question is how do i brace the Vinyl piece between the windows so there will be no movement between the 2 windows.
Can i put a screw in the Head & Sill of the window next to the middle piece to make it secure ?
