Pros and Cons of Sliding Windows

Posted on

Sliding windows, often referred to as gliders, to a large extent function similarly to double-hung windows. The only difference is that their sashes move to the right and left instead of up and down. Sliding windows typically have single or multiple functional sashes and sometimes may be combined with picture windows. The working sashes in sliding windows can tilt in, swing in, or be disconnected to allow for efficient cleaning of the glass’s interior and exterior sides.

Sliding windows provide multiple unrestricted viewpoints, adequate ventilation and are well suited for substantial horizontal rooms. And since sliding windows don’t go past the plane of the wall, they are more feasible for areas that endure heavy traffic, such as pathways, decks, and more.
