Sliding Windows & Short Walls

When you live in a home with short walls, sash or casement windows can often take up most of the space of your walls. This isn’t always aesthetically pleasing and can make the room seem short. Sliding windows are often used in manufactured homes for this reason because they make the room seem taller than it is. The windows take up more of the wall horizontally, but they don’t 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, your 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 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. If you are unsure which windows will work best for your home’s layout, it would be best to contact local replacement window installers in your area.
