DeerView Horizontal Slider Windows are a horizontally mounted twin sash sliding window. Both window sashes are based with double strength glass in which are then marine glazed in aluminum frame. Giving you the option of opening either end or lifting both sashes out giving you access to the entire opening. We recommend cutting the window opening 1/8” larger on the height and 1/8” larger on the width for each desired window size. I.E. For the 24” x 11 1/2” Horizontal Slider Window, we recommend rough opening of 24 1/8” x 11 5/8”.
