Casement window FAQs answered
What is a casement window?
A casement window is a vertically oriented window with hinges along the side, so it opens like a door. The top-to-bottom opening allows in lots of fresh air. It’s one of the most popular types of windows because of its ventilating abilities and its versatile design. We offer styles ranging from traditional to contemporary along with a range of materials. Find out everything you need to know about picking out a casement window.
Are casement windows more energy efficient?
Yes, casement windows are one of the most energy-efficient window types. With a single sash, they have a simplified design, which means fewer opportunities for leaking air. In addition, their seal is very secure because the hardware pulls the sash into the frame. It actually tightens when the wind blows. To make a casement window even more efficient, you can order it with triple-pane glass and a low-emissivity (Low-E) coating through the E-Series or A-Series product lines.
Are push-out casement windows available?
Yes, we offer push-out casements through our E-Series product line. Sometimes called “French windows” these windows include two casements with hinges out the outside and no center stile (bar where the two windows meet), so they offer a completely clear opening. If you love their old-world charm, check out our E-Series French Casement Window.
What are the advantages of casement windows?
Where to begin? Casement windows are versatile in terms of style — disguise them to look like a double-hung window or order them with a contemporary profile. They’re one of the most energy-efficient types of windows. Their cranks make them easier to operate, especially if you’re reaching to open them. Their verticality means they can let light and air absolutely pour into your space. Want to dive into more details about the casement window?
Where do casement windows work best?
While there’s no wrong answer to where casement windows work best, there are a couple of places where they truly shine. For example, in a kitchen where fresh air is important, you might be reaching over a counter or sink to open your window, and you might need a vertical window to fit between cabinets. Casements are also a popular choice in more modern homes. Their simple, single sash design means there’s more glass so the focus is on the view, rather than the window. But really, the range of options we offer means that a casement window can work anywhere. Read more about the congenial casement window.
