After the window has been secured in the rough opening, how do you finish the inside part of the installation? For example adding a window sill and trimming out the inner portion of the rough opening, not the finishing trim around the window. Also does anyone have any videos or pictures of the process? The type and maker of the particular window i am installing is a ThermaStar by Pella 28" x 36" 10 Series Vinyl Double Pane Single Hung Window. Thank you

What kind and make of windows do you have? Different styles are finished differently. –  Niall C. Mar 1 '12 at 21:41
