The windows in your home will last for about 20 years with regular cleaning and maintenance.

If you’ve lived in your home for longer than that, it might be time for an update. Not sure about the age of your windows? Some warning signs include warped frames and foggy glass.

As you shop for replacement windows, you’ll run into a lot of options including casement, double-hung, and sliders.

What is a slider window, you ask?

Read on to learn about slider windows as well as their pros and cons. Once you’re informed, you can make the best decision for your window replacement project.

What Is a Slider Window?

Slider-WindowA slider window is a type of window that you open horizontally. If you tilt your head to one side they almost look like double-hung windows.

Most slider windows have two glass panels with one moveable side. You can decide whether you want the moveable pane on the right or the left side.

You can also choose between single and double pane sliding glass windows. Double pane windows are worth the investment because they have two panes of glass. That’s great for insulation from outdoor temperatures as well as noise.

Types of Slider Windows

There are three main types of slider windows: single slider, double slider, and three-pane slider. Single sliders have one fixed pane and one moveable pane. The moveable pane slides back and forth on the sash.

Double sliders feature two or three panes of glass, but they have two panes that move. You can open either side of the window for more ventilation.

Three-pane sliders usually feature a large picture window in the center and a sliding window on either side.

Advantages of Slider Windows

One of the best things about slider windows is that they provide a great view of the outdoors. They have minimal framing so there’s not much that will block your view. They’re also usually wider than they are tall, so sliders have the dimensions of a picture window.

Sliders also come in bigger sizes than double-hung windows since they move right to left instead of up and down. Just by turning the window on its side so to speak, you can install a larger slider than you could a double-hung.

Since they’re wide windows, they also open wider. That means you can let in lots of natural light and fresh air.

Despite their large size, they’re often a very affordable choice for window replacement thanks to their simple construction. Just like sliding glass doors, slider windows simply glide along a track to open and close. Double-hung windows use a complex pulley system which is why they’re usually more expensive.

Slider windows are also easy to open and close. If you’re getting older and you’re concerned about accessibility, slider windows are a great choice.

They’re also great for difficult to reach places like stairwells and tight hallways. As long as you can reach the bottom of the window, you can open it. Most of the time you won’t need to worry about getting a step ladder.

Disadvantages of Slider Windows

While it’s easy to clean the inside of slider windows, it’s very difficult to clean the outside. Luckily, there are some types of sliders where you can tilt in or pop out the moveable pane. That said, cleaning will automatically be more difficult any time you have to take a pane out.

Dirt and debris can also get caught in the tracks which makes it harder to open the window. To keep your windows in good shape, you’ll also need to clean and lubricate the tracks of your slider windows.

A few times a year, use a vacuum attachment to clean up the tracks or wipe them with a damp cloth. Then, spray a little lubricant in the tracks and slide the window back and forth.

If your sliders have rollers as part of the window mechanism, you might have to replace them after a few years. While this isn’t too difficult, it’s still an extra piece of maintenance you might have to worry about.

Water can also pool in the window sill, which can lead to mildew growth or cause problems with the track. Make sure to pick windows with drainage holes to prevent this problem.

Slider windows don’t seal as tightly as casement or awning windows. That can make them less energy-efficient and pose a security issue. Luckily, windows that have interlocking meeting rails between the pains can prevent these problems.
