Sliding Windows and Short Walls

When you live in a home with shorter walls, sash or casement windows can often take up most of the space of your walls. This is not always aesthetically pleasing and can make the room seem smaller.

Replacement sliding windows are often used in manufactured homes for this reason, since they make the room seem taller than it is. The windows take up more of the wall horizontally, but they do not extend down very far on the wall. You get a seemingly taller room overall with the same standard sized window openings that you would have had.

Sliding Windows in Living Rooms

Casement windows tend to take up most of the wall that they are mounted on. This means that your couch, TV stand and all other furniture shows through the windows if you position it in front of them.

Horizontal sliding windows are wider, but shorter, and are often mounted higher on the wall so your furniture can sit under or in line in line with the windows. You can put your couch, table, and anything else exactly where you want it without worrying about the windows.

However, they are not as weatherproof as casement or awning windows. This is because you have to seal around the slides themselves, which can interfere with the function of the windows if not done properly.

Hinged windows tend to be more energy efficient than sash or sliding windows because they close tight against the frame when not in use forming a solid air-resistant barrier. If you are unsure which windows will work best for your home’s layout, it is best to contact local replacement window installers in your area.

Simple Design and Maintenance

Sliding windows rely on simple mechanics to open and close, making them easier to operate and less likely to break. The windows with two movable sections are more flexible because you can open either side of the window, or in some instances both sides of the window partially for improved ventilation.

Since sliding windows are so simple in design they tend to outlast other types of windows. They do not break often or suffer from most of the common issues that you will see in other windows. Worn out hardware is not common. Maintaining the windows is as simple as lubricating the slides once and awhile and vacuuming the dirt out before it can accumulate too much.
