Every Window Requires Screening Spline

August 29, 2016

 Screening spline is an absolute necessity in some implementations. This necessity of today is used for a piece of mechanical equipment called the window screen, popularly known as the bug screen, fly screen or even as flywire. It is mainly used in countries like the United States, Australia or Canada in order to prevent leaves, debris, insects or birds from entering a building or screened structure. The history of window screens date back as long as 1836 in Boyd's Blue Book.


Today, a majority of homes in the States, Canada or Australia have screens on all operable windows. From here starts the mention of the day: the screening spline.  It is used for holding screening securely in windows and doors, allowing continued support of the screen. For screens installed on frames made of elements like aluminum, the material is cut larger than the frame, laid over it and by using the spline, which is a flexible vinyl cord, is pressed over the screen into a groove or spline channel whatsoever name by which it may be addressed with. To perfect the screen, it is trimmed with a sharp utility knife close to the spline. Common spline sizes vary from 3.6mm to 4.8mm, with occasional increments of 0.25 mm.


The spline is often manufactured with parallel ridges along the length to provide better grip and compliance. These splines are used occasionally with Screen Room aluminum extrusions to secure the fiberglass screen materials. A spline roller is a special tool that consists of a metal wheel on a handle which is used to press the spline into the frame. There is such a variety of uses for screening spline, it’s no wonder it is considered such a necessity.
