Information about our Slider Windows

A sliding window is a horizontal window with sashes that slide back and forth. It is very much like a double hung window turned on its side. The window opens by moving the sashes to one side or the other.

Sliding windows work well on walls where there isn’t a lot of vertical height, yet there is plenty of horizontal area. They offer a more contemporary look than the traditional colonial style double hung windows.
