Casement Windows: Are They Good for Egress?

The beautiful thing about windows is that they all seem to provide the same function. They are majorly for ventilation, sunlight, delivering energy efficiency, and a nice spot to sit and enjoy the outdoor view. Well, not egress windows. These windows are for emergencies and have dimensions that ruin their essence if not measured accurately.

We have made a deep analysis and concluded that Ecoline Casement Windows are the best if you need this window style. But are casements the best to install, or you need to consider other options for egress? Let’s find out!

What are casement windows?

Casement is a window type with one or two hinges attached to the sides of its frame and a hand crank that allows you to open it outwards or inwards. They work just like a swinging door. This window type comes with a lock embedded in the frame for security purposes. Casement windows do great alone and work as a pair too.

Types of Casement Windows

Casement windows come in three major variants. Homeowners can choose what type they want, depending on their taste and budget. Here they are:

1. Single Frame Casement Windows

The most commonly installed casement window is the single frame casement window. It consists of a single frame and panels of glass in this frame. The panels of glass can be opened outwardly or inwardly and are usually separated by wooden strips. Most homeowners find it appealing and quite affordable.

2. Double Frame Casement Windows

If you crave a little bit of French fitting in your apartment, the double frame casement windows are what you need. Unlike the single frame casement windows, you get two windows hinged at the sides. Both windows meet in the middle when swung open.

The double frame casement window is also called the French casement window, as they operate like French doors. You get an uninterrupted view of your neighbourhood with this casement. However, installation is relatively expensive.

3. Push-out Casement Windows

The1 push-out casement window is a combination of both the single frame and French casement. It features a handle for operation instead of a crank. The push-out casement is the best for security purposes, as it features a multi-point locking system.

Opening Degree

Installing it the Right Way
