Abstract
A screen door made of foamed polymer with heat welded joins between rails and stiles and a flat spline groove. The rails and stiles are extruded with the flat spline groove. Prior to joining the rails and stiles, a thin notch is made to remove the smooth skin of the extruded stiles before being joined to the cut ends of the rails. The heat welded joint between the notched stile and cut end of the rail is ten times stronger than conventional polymer door joints. A flat spline is used to insert the marginal portion of the screen into the flat spline groove, which is wider in the interior than at its entrance and resists the pull from normal forces on the screen much more effectively than a round spline in a rectangular groove.
