Sliding windows, also known as gliding windows, were invented in the 13th century in Europe. During this time, they were just wooden shutters sliding vertically and therefore referring to them as sliding windows could be a stretch. However, they have been improved to horizontal windows with sashes sliding back and forth instead of up and down traditional windows. 

When putting up a building, whether an office or a residential space, windows are key to the finished design. It is essential to choose a type that suits the geographical location’s scenery and your needs.

Sliding windows are majorly found in rooms where topmost ventilation is required or a desire for an unbarred view of the outdoors. They are popular in laundry rooms, bathrooms, and kitchens to ensure an easy and quick way of ventilating the rooms. They are also suitable for use in hard-to-reach spaces and areas where one wants air but it is challenging to reach the window. For office space, reception areas, healthcare waiting rooms, and any place where people walk up to a counter for service, sliding windows, and pass-through sliding panels are a perfect solution.

Which Direction Should Sliding Windows Open

Depending on their configuration, sliding windows open in several ways. The most popular is having a fixed pane of glass and another gliding pane. The second one is a single-window frame having two sliding glass panes, where both panes move and slide past each other. Another is having a solitary fixed glass pane centrally placed and a sliding pane on one or both sides of the fixed pane. Lastly, one can have two or more fixed panes of glass and one or more panes of sliding glass.

Types of Sliding Windows

Sliding windows are made of different materials. The most commonly used are PVC, aluminum, or timber, with each of these having its share of benefits. Those made of PVC are remarkably low maintenance, entirely energy-efficient, and last for years. On the other hand, aluminum is low maintenance, durable and glamorous since it can be powder coated to the color of one’s desire. Timber ones look good and can exhibit the timber’s natural beauty, or they can also be painted to whatever color that one fancies.

Sizes of Sliding Windows

Sizes are usually dependent on one’s requirements. Sliding windows can come in large sizes for living rooms and smaller ones for bedrooms, with the average size is 48 inches by 48 inches. The horizontal width size ranges from 36 inches, 48 inches, 60 inches, 72 inches, and even 84 inches. The height range is from as small as 24 inches to as tall as 60 inches.

In living rooms, casement windows take the better part of the wall on which they are mounted; therefore, the house furniture shows through the windows if you position in front of them. Horizontal sliding windows are, however, wider, shorter and usually mounted higher. This way, the furniture can be placed inline or under the windows. This ensures that you can have the furniture exactly where you want it to be without worrying about the windows.

How Much Does Sliding Windows Cost

The prices of sliding windows depend on the type of frames used and the material. The main price factor is usually the brand of windows one has chosen. Most brands offer affordable prices for their widows, but one can spend more if they want a premium window with useful features. Generally, they cost anything between $250-$600 to buy and a minimum of $250-$500 to install. 

Are Sliding Windows Secure?

It is possible to secure a sliding window. One way of doing this is by installing a metal clip, which will prevent a burglar from opening the sash. You can also add a bar that can be raised and clipped against the inner sash when not needed. The most secure way is by installing key-operated locks. 

With technology and the architectural world’s evolution, installing the first sliding window system for high-rise buildings has been made possible. This project by Air-Lux, a Swiss company, has, under strict US testing conditions, proven itself. In the recent past, there was always a question about their suitability in skyscrapers due to high demands regarding air, water tightness, and their inability to accommodate building movement. However, Air-Lux has proven it possible to meet the US market life-cycle and earthquake test’s high requirements.

You may be curious as to why you would choose sliding windows over any other type of windows. Here are some of the advantages and disadvantages.

  • With these, one incurs low maintenance cost. They have fewer moving parts hence excellent energy efficiency. Besides, this aspect helps in lowering the cost of maintenance.
