Timber Door FAQ’s

What are Casement Windows?
Casement windows are a popular and versatile style offering endless configurations to suit different apertures and a wide range of property types. Hinged at either the side or the top, casements can combine with blind panels that don’t open in a large bay or feature window. Practical, high-functioning, secure and thermally efficient, casement windows offer a limitless choice of styles and glazing to suit houses from the truly ancient to the latest contemporary design.
What is the maximum size for a casement window?
There is a maximum size on casement windows because of various risks, unlike fixed windows and sliding glass. There is a limit to how much the holding mechanisms can support. The maximum height and width are 6 feet 8 inches and 3 feet 2 inches, respectively. A double-hung window can be 10 feet tall or perhaps a little bit higher, and at least 5 feet wide.
How far do casement windows open?
Casement windows can open as far as 90 degrees to let fresh air in. The crank device keeps the window secure even when it is fully open.
Are casement windows safe?
A casement window is among the safest types of windows for a home since, when closed and latched, it cannot be opened from the outside.
