How casement windows work
Casement windows tend to either be:
A casement (the part that sits in the frame) that’s made from 4 pieces of wood that have been joined together. Inside the frame there’s glass that’s hinged to the frame or;
A casement that doesn’t open because it’s been fixed shut. In this instance, each opening has hinges. However, having too many hinges isn’t a good thing because it can overcrowd the window.
The history of casement windows
To the left is a sketch of a casement window from an old joinery and carpentry book published in 1902. Joiners who built period properties around London back then learned from books like these.
While we may be in the 21st century, we pride ourselves on the fact our timber casement windows are made with the same features as those that were made 100 years ago. They also happen to incorporate some additional valuable features too!
