I want to put a picture window on a wall where there is no window.

The view from the side is pretty and the light would enhance the living
room.

The interior wall is plasterboard and the exterior wall is vinyl
siding.

The size of the picturewindow area is appr 7' x 4'.

Has anyone out there had a similar size window installed??

Am looking for advice based on your experience.

What ballpark expense am I looking at for the installation?

Thanks much gor your advice/help!

Jim
