I built my porch screen door out of red cedar in 2011 and it has worked
out great.This replaced a big-box screen door installed in 1993 by the
contractor who built the porch. The original was some sort of non-durable
wood.

The door is very lightweight. The simple design in the lower half was
chosen to be decorative, but also to incorporate the diagonals for rigidity
against racking. As far as I can tell, the door hasn't sagged even a
fraction of an inch in eleven years. It is fully exposed to weather, so it
doesn't look as new as the photo any more, but has held up quite well
nevertheless.

It has removable panels (more like frames actually) top and bottom, each of
a different design, but both held in place with a tongue and groove at the
bottom and concealed rare earth magnets along their upper frame. The lower
panel sandwiches a loose acrylic panel against the door frame, with no
option for a screen. The upper panel has a stapled on screen, always in
place, plus a slot which allows an acrylic to be slipped in behind the
screen for the winter.

I installed a pneumatic closer. The handle on the outside is a scrap of
mahogany.
