Screening is usually made from either fiberglass or aluminum. Aluminum is stronger than fiberglass, but it is subject to corrosion and harder to install. Make sure to use the same material and color as your other screens unless you are replacing all of your screens.  You can buy the screening in different lengths, either by the foot or in rolls. Purchase enough screening to cover the entire screen frame at with at least a 2-inch overhang on all sides.

The screen is held in place by a spline pressed into a groove in metal frames. Most of the splines are made from vinyl or rubber. As long as vinyl or rubber is still in good condition, you can reuse it. If the spline is dry or cracked, you will need to replace it. When replacing the spline, make sure you bring it with you to buy the new one. That way you can ensure a good fit.

If you have a wood frame, the screen is stapled directly to the frame it’s self. Use molding to cover the staples and the edges of the screen so it will have a neat appearance.
