What is a steel casement window?

A steel casement window is a window that is hinged and opens and closes like a book, by swinging either in or out. It consists of a frame, hinges, and a handle or crank that operates the opening and closing mechanism. There are several styles of steel windows.

A typical steel casement window is vertically hung, hinged on either the left or right side and opens out.

Frame and Shutter Construction Comparison

Frames and Shutters can be made of the following materials:

Material Thermal resistance Durability Maintenance Cost Recycled content Comment
Wood very good variable high high low Shrinks and swells with humidity changes
PVC/UPVC very good Good* low high very low Colour changes with humidity changes
Aluminium bad Low low low typically > 95% Colour changes with humidity changes
Steel Very good superior very low Moderate > 98% No Shrinks and swells with humidity changes

"PVC is not as strong as other materials, it's good if PVC/UPVC frames are reinforced with Steel or composite materials to improve their structural strength. Steel window frames are typically filled by a thermal break made of a PUF. This greatly increases thermal resistance, while retaining virtually all of the structural strength.

Steel casement windows are harder to break into

Steel casement windows are very difficult to break into. Casement locks are hook-shaped, and these hooks are embedded within the frame, making them untouchable.

For homeowners who prefer this type of steel window, new replacement styles are readily available in a wide selection and are considered to be both affordable and energy efficient.
