Guide to Window Screen Spline and How to Choose for Your Windows

How to Choose Window Screen Spline Guide

If you have ever had to put a new screen in a window, then you know how important it is to have the right spline. Spline is the rubbery cord that holds the screen in place in the window frame. There are different sizes and types of splines, so it is important to know which one to use for your project. This guide will teach you everything you need to know about window screen spline and why it is so important for your home and office.

What is Window Screen Spline?

Window screen spline is a type of rubber or vinyl that is used to hold the screen in place on a window. It is inserted into a groove on the frame of the window and then the screen is placed over it. The spline helps to keep the screen in place and provides a seal against drafts and insects.

Window screens are important for homes because they allow fresh air to circulate while keeping out insects and other pests. Screen spline is the rubber or vinyl cord that is used to secure the screen fabric to the window frame. There are different types of screen spline, but the most common is round and made of black vinyl.

To install screen spline:

  • Start by removing the old spline and cleaning out the groove.
  • Next, cut the new spline to size and insert it into the groove.
  • Use a roller or your fingers to press it into place.
  • Finally, trim off any excess spline.

How to Choose the Best Window Screen Spline Material

There are a few things to consider when choosing the best window screen spline material.

  • The first is the type of screen you are using. Fiberglass screens are the most common, but aluminum screens are also available.
  • The second consideration is the size of the opening you are trying to cover.
  • The third is whether you need a clear view or not.

Fiberglas – If you are using a fiberglass screen, the best spline material is probably rubber. Rubber has a lot of give, so it can grip the mesh tightly without tearing it. It’s also easy to work with and inexpensive.

Aluminum – If you have an aluminum screen, vinyl is a good choice. It’s stiffer than rubber, so it will hold the mesh more securely. And it’s clear, so it won’t obstruct your view.

Review of the Different Types of Window Screen Splines on the Market

Window screen splines are one of the most important parts of a window screen. They provide a secure attachment point for the screen to the window frame, and they also help to keep the screen flat. There are many different types of window screen splines on the market, but they all do basically the same thing. So it is important to know which type will work best for your needs before you buy them.

Ribbed Foam Window Screen Spline

The ribbed foam window screen spline is a type of window screen that is made from a foam-like material. The ribbed foam window screen spline is typically used for insect screens, but it can be used for other purposes as well.

The ribbed foam window screen spline may offer some advantages over other types of screening materials. For instance, the ribbed foam window screen spline may be more resistant to tearing and puncture than other screening materials. This can make it more durable and last longer.

The foam screen spline can be used as a temporary formwork when constructing concrete walls or permanent formwork when building slabs on site.

The foam screen spline is made from flexible polyurethane foam, which is coated with a durable, waterproof, fire-retardant coating. This means that the foam screen spline can be used in both wet and dry conditions without compromising its strength or durability.

This product is designed for use in both residential and commercial construction projects. It can be used for many different purposes, such as to create formwork for slabs on site or to provide access during construction of concrete walls.

Foam Flat Spline

When it comes to repairing or replacing the weatherstripping around your doors and windows, you need to use the right type of spline. Foam flat spline is one of the most popular types of splines on the market.

Here’s what you need to know about using foam flat spline for your next door or window repair project.

Foam flat spline is a type of flexible foam that is used to seal gaps around doors and windows. It is available in different widths and thicknesses to accommodate different size gaps. To install foam flat spline, you will need a utility knife and a putty knife.

  • First, use the utility knife to cut the foam flat spline to the desired length.
  • Next, insert the foam flat spline into the gap between the door or window frame and the wall.

PVC Ribbed Screen Spline

PVC ribbed screen spline is an excellent product for those who want to ensure a tight seal between their screen and the frame. The spline is inserted into the groove of the frame, and then the screen is stretched over it. The PVC material is weather-resistant and will not corrode like some metal splines. It is also easy to install and remove, making it a great option for those who are not experienced in screen installation.


T-Spline screen spline is a unique system that offers many advantages over traditional methods of holding screens in place. The system consists of two parts: the T-spline and the screen clip. The T-spline is a small, plastic wedge that fits into the corner of the window frame. The screen clip is then inserted into the T-spline, forming a tight seal that holds the screen in place.

There are several benefits to using this system.

  • First, it is much easier to install than other methods.
  • Second, it provides a better seal against wind and weather.
  • Third, it is adjustable, so you can get a perfect fit every time.
  • Fourth, it is much more aesthetically pleasing than other options.

What are the Advantages & Disadvantages of Using a Window Screen Spline?

As the weather gets warmer, many homeowners begin the process of opening up their homes and letting in some fresh air. One important part of this process is making sure that window screens are properly installed and functioning. A window screen spline is a small, plastic or metal cord that is used to secure the screen material to the frame of the window. While this can be a helpful tool, there are also some potential drawbacks to using a window screen spline.

One advantage of using a window screen spline is that it can help to create a tight seal around the edges of the screen. This can prevent insects and other pests from getting inside your home through gaps in the screen. Additionally, using a window screen spline can also help to extend the life of your screens by preventing them from tearing or coming loose from the frame.
