Vinyl Casement Windows

Casement Window: How It Works

A typical casement window is composed of the following elements:

• Frame. It can be fitted with a brickmold outside, jamb inside with casing.
• Sash. It’s the part of a window that holds the glass.
• Locking mechanism. It’s composed of the level handle, bar with rolling pins and the hooks on the sash.
• Crank mechanism. It opens and closes a window by twisting the handle.
• Hinges. They hold the windows on top and bottom supporting their weight.
• Weatherstrips. They ensure a leak and draft proof window when it’s closed.

Casement Windows Styles and Types

Casement windows are a common option in today's world, and for good reason. They're a perfect choice for homeowners who want unobstructed sightlines because they crank open and swing outward. Casement windows, unlike other types of windows, do not have a centre rail.

When most people think of casement windows, they think of single casement windows. There are, however, several other types of casement windows available. Let’s see what they are:

Double Casement Windows

Double casement windows, also known as vinyl French-style casement windows, have two sashes that open from the middle and don't have a centre stile, allowing for a large, unobstructed view. This one-of-a-kind option has hinges on both sides and can be operated by a single, easy-to-reach handle. Double casement windows are beautiful and can significantly improve the appearance and feel of your home.

Out Swing Casement Windows

The most common form of casement window is outswing casement windows. The majority of people like their windows to swing outward so they don't have to think about moving curtains or shutters in their way. This style is the most popular for single casement window replacement, but can also be split or combined with many other styles like picture or fixed casement. By default, the casement window is double pane, but triple is getting more and more popular because of its higher energy efficiency values.

In-Swing Casement Windows 

This sort of casement window is just as it says on the tin. Instead of swinging open to the outside, it swings open into your house. It's as easy as turning the handle and pulling. For rooms where a swing-out sash would get in the way, such as in front of a bush, porch or next to a driveway, casement windows that open in are an alternative.

Push Out Casement Windows

Casement windows with a push-out feature are one-of-a-kind. Instead of using a crank, they use a handle and a gentle push to operate. Push-out casement windows are a great option for those who want to open their windows with ease and simplicity. To fit the aesthetic of your home, these windows are available in both traditional and contemporary designs.

Victorian Casement Windows

The windows with grills or mullions are commonly referred to as Victorian casement windows. SDL bars, outside on both glass panes would give the most realistic match of the traditional Victorian style windows which were once only available in hardwood or softwood timber materials, but thanks to technological advances, this much-loved style can now be reproduced in either aluminum or uPVC.

Casement Windows Sizes

Almost all windows used in homes do not come in standard sizes, they all get custom made to fit the openings available. ​There are some common sizes used by builders as 36 x 36" or 48 x 42" casement windows, but it's a small fraction of the market. It's actually cheaper and easier for the manufacturer to make the new windows rather than store all available sizes, which are pretty much endless.

Any size casement window can be made as long as it's within allowed size restrictions. At some point, the window becomes too small to fit the operating mechanisms inside the window or too big for those to hold the window's weight. The double-pane casement window should not be wider than 32" (can be pushed to 36" if it's short) and 66" height (can be pushed to 72" if it's narrow). For triple-pane heavier windows, it's 25" x 59".
