Slider and Single Hung Windows

Supreme Windows & Doors has been the leader in providing slider windows for Edmonton for years. Our horizontal slider windows open with the sash sliding left or right that allows for ease of use. Horizontal sliding windows make for an excellent choice for rooms facing walkways, porches or patios as they slide open without protruding. In a single slider, one sash slides to open. You can also choose single hung windows for rooms facing walkways, porches or patios. Since the top sash is fixed, they open without protruding.
