Hi All,

I have a sliding screen door on a sliding glass door.
Is there a such thing as an opaque screen door material
that I could replace the screening with? I want no
light, but I want air flow.

Many thanks,

I think light is smaller than air, so something simple is unlikely.

But light travels, generally, in a straight line, while air can bend,
so maybe you can mount two grids that are offset from each other.


I wonder if I could keep them lines up ...

Thank you for the help!
