A horizontal sliding window is a type of window where the sash(es) operate(s) by sliding along a track in the window frame. Slider windows have fewer parts than conventional windows, making them a low-maintenance and cost-effective choice for residential homes. Slider windows don’t rely on springs and pulleys to function, making them more durable than conventional windows. Most slider windows also use window glazing, adding to their durability. Slider windows require very little effort and dexterity to open and close. They aren’t heavy and they glide along the window frame with ease. To use, all you have to do is release a latch and slide the window open.
