Casement and awning windows

Casement windows

A casement window has the sash attached to its frame by joints installed on the side. Casement windows swing outward with the easy turn of a handle placed near the bottom center of the window. Casement windows were first used in the UK during the 18th century and were made with heavy iron frames. Nowadays, casement windows are a popular choice for many homes all over the world – due to the window type’s simplicity, versatility, and numerous advantages.

Available in several different configurations and frame color options, choose this design for remodeling or new construction for commercial and residential projects.
