Everything You Need To Know About Screening Splines

September 01, 2021

Screening splines are a crucial component in holding windows and doors together. These materials essentially keep the screen material of a door or a window in place. However, you might need new screening splines for a home improvement project or perhaps you may want a quick replacement. Either way, it can be confusing to select the right material with the right dimensions for the job.

To make things clear, here's a short guide to help you understand the basics of screening splines.



Screening splines are usually made from plastic and rubber-based materials, as window screens need to penetrate them. Depending on your needs, splines can be classified in the following two ways. 

Vinyl Splines

Using a vinyl material for screening splines offers reduced flexibility than foam splines. However, the upside is that they have better penetration resistance, allowing them to hold screen material efficiently. 


Foam Splines

Foam is much more flexible than vinyl. In addition, it is much more versatile in terms of size, making it ideal for a variety of frames. Moreover, foam screening splines do not use soft filler foam. The foam used here is quite resistant in nature and can be penetrated without any damage. For the most durable and quality foam screen splines, you can always trust Alcot Plastics LTD, the leader in manufacturing versatile and easy-to-install screen splines.  


Types of Screening Splines

Your local screening spline retailer will likely offer you two types of screening splines. Each one has its respective benefits.


Serrated Screening Spline

Using serrated splines guarantees the best screen material grip as it snugly fits your window. These are ideal for windows or doors that won’t undergo significant modifications for a long time. Make sure to select the right size.


Smooth Screening Spline

Smooth splines insert into your window and door frames easily. Although it can be argued that its grip strength is lesser than its serrated counterpart, it does offer adequate grip. In addition, it can be easily moved or removed for minor spacing adjustments.


DIY Screening Spline Installation

You can install screening splines on your own because removing old splines is easy. You'll just need to remove the spline frame. Consequently, you can easily remove the old spline. If damaged or splitting, it can be removed with a sharp object. You can measure and cut the screening splines according to your frame's needs, or if you want to avoid that hassle, just take the old spline to your local screen spline retailer and they can recommend the right size.
