Different Types of Windows Available for Installation

Double Hung Windows

When it comes to home decor, the devil is in the details. So, it’s important that your windows give you a look that’s on-trend, with all the function and energy efficiency you want. If you want to go for a classic look with modern materials and performance, you should consider double-hung windows from Window Worx Replacement – St. Charles

Double-hung windows are what most people think of when they picture window replacements: they have a vertical sliding panel at the top and bottom, allowing you to open either or both as needed.

Double-hung windows are also easy to maintain because they tilt inwards for simple cleaning. And because they’re made by Integrity Window Replacement they’re built with extremely durable materials and will give you years of worry-free use!

Sliding Windows

Sliding windows are versatile. They can be easily fixed on any side of the house or building since they slide open horizontally. This means you can set them up to give you a lovely view of the outside or to let in as much fresh air as possible for your indoor space.

Sliding windows are also cheaper than many other types of windows, and this makes them an ideal choice for home improvement projects on a budget. Plus, they are easy to operate, meaning that even small children can learn to use them with little supervision.

Another advantage of sliding windows is the fact that they require little maintenance. This is because the tracks in which they move don’t get dusty and dirty easily, and their cleaning is also quite easy compared to other types of window replacements.

Awning Windows

Awning windows are perfect for areas of your home where space is at a premium. They’re hinged at the top and swing outward, so they don’t take up any precious space inside your home.

They’re also exceptionally easy to open and close. All you need to do is lift the window to open it and crank down on the handle to close it. This makes them a great option for bedrooms or other places where you want to be able to let in fresh air without having to get out of bed.

And because they have a much smaller surface area than other types of windows, you won’t have to worry about cleaning them all that often! Just wipe them down with a damp cloth every now and then, and you’re good to go!
