The Benefits of Using Foam Screening Spline

June 12, 2023

Window and door screens are inextricable parts of your house. The screens need to be firmly attached to their slots or brackets to do their job well. After all, a loose window or door screen is as good as no screen. If the screens are not firmly attached. not only does the resultant draft lead to higher energy bills but also provides space for pesky bugs and debris to enter your home. There is a solution to this problem, foam screening splines! In this blog post, we'll explore the advantages of using screening spline.

The Benefits of Using Foam Screening Spline

  • Screening spline may not be a term that many people are familiar with, but it is an essential component of window and door screens. This type of spline is made from polyethylene foam rather than traditional materials like rubber or vinyl.
  • One major benefit of using a screening spline is its ability to absorb shock and pressure. This means that the screen will be less likely to tear or come loose during high winds or heavy rain. The foam also provides a tighter seal between the screen and frame, preventing insects and other pests from sneaking their way inside.

  • Unlike traditional splines which can crack over time, foam splines remain pliable even in extreme temperatures. The flexibility of screening splines made of polyethylene foam is unmatched, making them ideal for all conditions.

Tips for Using Foam Screening Spline

  • Before inserting the spline into the frame groove, it's helpful to lubricate it with a small amount of soapy water or silicone spray. This will make insertion easier and prevent tearing or stretching of the mesh.
  • When inserting the spline, start at one corner and work your way around in a clockwise or counterclockwise direction. Use a roller tool specifically designed for this purpose to press down firmly on the spline and secure it in place.
  • Take care not to stretch or distort the mesh while installing the foam screening spline. If necessary, use clamps or weights to hold everything in place until you're finished securing all sides of the screen frame.
