Types of Windows And Their Definitions

One of the most important architectural features of your home is the windows. They provide more than just light and great views. Make sure you choose the right windows for your home.

Double-Hung Windows

If you’re looking for windows that can open wide from the interior of the home, select double-hung windows. They slide vertically up and down in the frame, opening either from the top or bottom. Opening both creates natural air convection inside your home. The windows always remain inside the frame, so they can’t protrude from the house. Many models also tilt inwards for easy cleaning.

Casement Windows

If you want a window that can open outward, choose a casement window. It opens on a hinge operated by a crank on either side of the window, and allows you to open it as wide as you’d like. Crank windows offer excellent ventilation. They have a seal that wraps around the entire window it’s shut, keeping inside air in your house, outside air out. The seal also provides noise reduction. Casement windows won’t work near a walkway or deck.

Awning Windows

Awning windows are hinged at the top and open outward to let air in from the left or right side, and from the bottom. You can install them above, below, or alongside a stationary or operating window. When you open the window, the glass slopes downward. This allows you to open your windows when it rains outside, because the slope prevents the rain from coming in. A small awning window can be placed near the top of a wall to let hot air escape. But they only allow partial ventilation, and won’t provide an evacuation route.

Stationary Windows

This large, fixed window allows the maximum amount of light into your home, as well as the views of the outdoors. Maintenance can be easy or not, depending on their size. You’ll want to put them in a room that doesn’t need ventilation, or mix them with another window style that will provide ventilation. Stationary windows are great for creating a sunroom, or letting light into a cramped stairwell. They come in a variety of shapes and sizes.

Transom Windows

A transom window is usually installed more for looks than functionality. It’s a narrow window that can be either operating or stationary, and usually mounted above a door or another window to let in more light. They come in a variety of shapes and sizes to add an extra stylish feature to your homes current windows and doors.

Slider Windows

Sliding windows have at least one operating window that slides horizontally over or past another window. They are typically used in contemporary- or modern-style homes. You can choose from a variety of sliders, depending on the size of your window. Smaller windows will work with a single-slider, while larger windows work better with a double-slider. If the window is large enough, you can place a stationary picture window in between two sliders.

Any of these windows would look great in your new or remodeled home. Pick the one that works with your home’s style and functionality.
