The Benefits of Sliding Windows
Sliding windows work best for wide, low openings where the sash has to move sideways and stay inside the wall. You get ventilation without a crank swinging over a deck, a walkway, or a narrow side yard. The glass rides a track. It doesn't stick out past the siding when open. A single unit has one sash that slides and one that stays fixed. A double unit lets both sashes move, so you can open either end of the same frame.
