Importance of Screening Splines in Windows

Safety is one of the most important benefits that windows offer to buildings and homes. The ability of windows to be able to let natural light and fresh air in while still being able to offer protection against elements and insects is extraordinary. However, to offer protection against elements and insects, it is crucial for the window screen to be securely attached to its frame. This is where screening splines come into play. Foam splines play a crucial role in creating a flawless joint between window screens and the frame. We list in this blog the crucial role that foam splines play in having a safe and secure window.


The Role of Screening Splines in Windows

 Screening splines may seem like a small and insignificant component of windows, but their role is crucial in ensuring the functionality and longevity of the window screens. Imagine building a beautiful home only for the windows to be useless or not visually appealing. These thin strips of material play a vital part in securing the screen mesh within the window frame, preventing it from sagging or being easily dislodged.
Foam spline provides tension to the screen and keeps it dent-free. The firm grip that splines offer helps the spline fit perfectly into the groove on the window frame, thus ensuring protection against harsh elements. The spline fits into a groove on the window frame, creating a firm grip on both sides of the screen mesh. This secure attachment helps to maintain proper airflow while keeping insects and debris out.
Good quality screening splines are crucial as they create a barrier against drafts and leaks, thus helping keep energy bills in check. In addition to their practical importance, screening splines also contribute aesthetically to windows. Available in various materials such as vinyl or rubber, they can be matched with different frames for seamless integration into any architectural style.
