I'm at my parents' house this week, clearing fences, doing repairs and stuff. The last thing on my list is fixing the torn screen door. The old screen is aluminum (probably purchased a long time ago), and appears to be installed with 0.160" spline. I am going to be using fiberglass screening because it is more tear resistant. Will I need .160 spline, or .175 since the fiberglass material is thinner? Or does it even matter? How tight do I stretch the screen before I spline it? (I assume I just lay it flat with no wrinkles, and no tension until I do the 3rd and 4th sides) Thanks, Bob

If you already have the .16 spine material try it and see how it feels. If the new screening is truly thinner, then the .175 material should be the winner. All three sides after the first need to be stretched tight, even the second one. If you do not tension it, you may have a sag at the corner where the first two spines are installed.
