Foam screen spline is a type of spline used in screen installations for windows and doors. It is used to secure screening material to a frame, creating a tight, secure fit. Foam screen spline is different from traditional rubber spline in that it is made of a foam material, typically a closed-cell foam, that provides additional benefits over rubber spline.

The following are some of the characteristics of foam screen spline:

1. Durability: Foam screen spline is more durable and long-lasting than rubber spline. It is resistant to UV rays, weathering, and other environmental factors.

2. Flexibility: Foam screen spline is flexible, allowing it to bend and conform to the shape of the frame without cracking or breaking.

3. Easy Installation: Foam screen spline is easier to install than rubber spline because it is more pliable and can be cut to length with a regular pair of scissors.

4. Energy Efficiency: Foam screen spline provides a tighter, more secure fit than rubber spline, reducing air infiltration and improving energy efficiency.

5. Weather Resistance: Foam screen spline is resistant to weather and moisture, making it ideal for use in areas with high humidity or exposure to the elements.

In summary, foam screen spline offers several advantages over traditional rubber spline, making it a popular choice for screen installations. It is more durable, flexible, easy to install, energy efficient, and weather resistant, making it a reliable and effective solution for securing screening material to a frame.
