Single/ Double Hung Window Single/double hung windows slide vertically within a fixed frame, which means they don’t require any extra outward or inward space to open or close. This is especially useful in rooms with limited floor space, near furniture placements, or where you want to prevent the window from extending into the room or overhanging the exterior. When fully opened (with the lower sash lowered for single hung, or both sashes adjusted for double hung), these windows can deliver a wide, unobstructed view of the outdoors, maximizing natural light penetration and strengthening the visual connection between the interior and exterior spaces. | ![]() |
