Screen Spline Basics: What Material to Use Screen Spline Basics: What Material to Use

An old screen spline can spoil the appearance of a screen door. A weathered, loose screen spline that is showing signs of cracking should be replaced. However, you should be aware about the various screen spline options for your screen door or window.

Vinyl T-shaped Splines

Most of the contemporary screen frames are made from light metals like aluminum. Other common screen choices include plastic and fiberglass screening materials. These are poor conductors of heat and impervious to water. Hence, these screens are less likely to lose their shape when subjected to extreme temperature conditions. All these screening materials can be easily supported by a vinyl screen spline.

Some features of T-shaped vinyl screen spline that should help you make a more informed decision have been listed below:

  • Vinyl T screen is often referred to as T-spline because it consists of a cross-section that resembles the shape of the letter “T”.
  • Due to its inherent strength, vinyl T screen splines are the most recommended option for storm doors and windows. They are structurally more stable than rounded or square-shaped splines of any material.
  • Vinyl T screen is flexible in terms of the size requirements. It can be rolled repeatedly to stretch it along the edges of the spline channel to ensure a comprehensive coverage—this is also a money-saver since lesser spline material covers more area.

Other Screen Spline Material Choices:

  • Rounded & Square Splines—considered less stable than T-shaped splines.
  • Rounded Polyfoam—a decent performer but has limited elasticity, meaning more expenditure on the spline material.
  • Flat-screen splines—a conventional choice, now looked upon as outdated.
