What is a Casement Door? A Comprehensive Guide

What is a Casement Door?

Definition of Casement Doors

A panel operating on hinges, usually fixed on either side, is known as a casement door. These doors are used to provide access from one side to another. Casement doors are always directly mounted on the floor.

Types of Casement Doors

There are only two possible designs for the casement door: single panel and double panel. As the term suggests, a single panel comes with a single sash, whereas a double panel comes with a double sash. Moving forward, in the double panel, it can be classified as with a flying mullion or without a flying mullion.

Definition of Single Panel Casement Doors

Let’s talk about single panels first. In this design, there can be only a single pane fixed on either side of the frame, and the hardware on which they are fixed is commonly known as hinges. The panel swings on these hinges, performing a to-and-fro movement across the frame. If the weight of the sash is not calculated properly, then, in that case, the panel usually sags on one side, creating noise and also requiring more effort in opening and closing the door. The width of one panel starts from 2 ft and can go up to 3.5 ft, whereas the height starts from 7 ft and can go up to 10 ft. We can also use glass thickness starting from 5 mm toughened glass to 24 mm DGU. If the width or height of the aperture is beyond the product capacity of a single panel casement door, then, in that case, we can fix either the side part or top part of the door, and it will be really cost-effective. For example, if the total available aperture size is 5*7 ft, then, in that case, we can fix the side part of 2*7 ft and can use the rest 3*7 ft as a casement door. Similarly, we can do for height.

Now let’s talk about a casement door with a double panel. These doors are mostly used where the aperture opening in width is more than 3 ft, and we need access through it. On average, we can make casement doors with 6 or 7 ft in width as well as 7 ft in height. In casement doors, again, there are two options: either with a threshold or without a threshold.

Casement Doors With Or Without Threshold – Definition & Benefits

The basic meaning of a threshold is a limit. In technical terms, there is a strip fixed at the bottom of the frame that further disallows any external object to penetrate, such as air, dust, water, noise, etc. So, when you are thinking of buying a casement door, you may get an option from sales professionals asking whether you wish to buy a door with a threshold or without a threshold.
