Friction stays, scissor stays, and other window support systems provide a wide range of options for casement windows. Understanding the advantages and disadvantages of each type is crucial for selecting the right solution for your window applications. This article delves into a comprehensive comparison of casement friction stays with other window support systems, highlighting their key characteristics and suitability for various scenarios.

Functionality and Design

Friction stays and scissor stays share the primary function of holding casement windows open at desired angles. Friction stays rely on a friction mechanism to maintain the window position, while scissor stays employ a scissor-like linkage system. Scissor stays offer more stability and allow for wider opening angles, making them suitable for larger windows or those requiring increased ventilation.

Durability and Maintenance

Casement friction stays are generally more durable than scissor stays due to their simpler design and fewer moving parts. They are less prone to wear and tear, resulting in a longer lifespan. However, friction stays require periodic lubrication to ensure smooth operation, while scissor stays may require more frequent adjustments or repairs due to the increased complexity of their mechanism.

Installation and Versatility

Friction stays are typically easier to install than scissor stays, making them a more cost-effective option for simple applications. They are also more versatile and can be used with various window sizes and materials. Scissor stays, on the other hand, may require professional installation for larger or heavy windows and offer less flexibility due to their specific design requirements.

Aesthetics and Customization

Friction stays have a discreet design that blends seamlessly with most window styles. They are available in different finishes and can be customized to match the window’s color. Scissor stays, while less aesthetically pleasing, offer a wider range of customization options, including different colors and handle designs to complement the window’s overall aesthetic.

Energy Efficiency

Both friction stays and scissor stays can contribute to energy efficiency by providing airtight seals that reduce air infiltration. Friction stays have a slight advantage in this regard, as their simple design minimizes potential air leaks. However, scissor stays can also provide excellent sealing with proper installation and maintenance.


The choice between casement friction stays and other window support systems depends on the specific requirements of the application. Friction stays are a reliable and cost-effective option for smaller windows or basic applications, while scissor stays offer superior stability and versatility for larger windows or those requiring increased ventilation. By carefully considering the factors discussed in this article, you can select the optimal window support system to meet your functional, aesthetic, and energy efficiency needs.
