Gas Strut Window VS Awning Window

Gas strut awning windows create a beautiful and natural path from the interior to the exterior of your home. The essential advantage over an awning window is that the gas strut window opens and locks at a whole ninety-degree angle. 

Gas strut windows are true pass-thru windows. With no bottom rail or support to get in the way of serving foods and drinks directly from your kitchen to the outdoors, this window offers a seamless transition from the outside to the inside!

90 Degree Open or Not

This is the most critical difference between gas strut windows and awning windows. The gas strut system allows the gas strut window to open fully 90 degrees, while the awning window can open only about 45 degrees.

Hardware System

The gas strut window uses a gas spring to hold it open to 90. However, the awning window uses a friction stay hinge to open 45 degrees.

The friction stay hinge is usually made of stainless steel, and you can adjust the opening degree. However, the standard opening degree is not more than 45 degrees. The opening angle is usually less than 110MM to prevent people from reaching their heads to the ground.

Frame materials

The gas strut awning window, which is a type of window that uses compressed gas to hold the window open, is presently available only in non-thermal aluminum profiles. On the other hand, the awning windows are available in three different frames – uPVC, thermal break aluminum, and non-thermal aluminum. The uPVC frame provides excellent insulation due to its multi-chambered design and is an energy-efficient option. The thermal break aluminum frame is also energy-efficient and a good option for those who want a more durable and sturdy window frame. The non-thermal aluminum frame, however, is the most economical option and is suitable for those on a tight budget. With these three frames, you can choose the best suits your requirements and budget.

Size Limits

Gas strut awning windows are designed to provide efficient and effortless operation, making them an ideal choice for larger windows. These windows have a maximum height of 1800mm and width of 2410mm, which makes them perfect for spaces that require a lot of natural light. On the other hand, awning windows are smaller and better suited for compact spaces. They are hinged at the top and open outwards, making them an excellent ventilation option, even during rainy weather.

How do you close a gas strut awning window from the inside?

Since the window opens at 90 degrees, your hand cannot reach the pull handle when it is open. For this reason, we will include a pull hook that you can use to snap the handle and close the window. The hook is customized to the size and weight of the window.
