   I hope this isn't a double post. I posted the same message last night
and I haven't seen it  migrate to the news server, So I'm reposting.
Odd... very odd...

I went out to buy some window screen for my quickie solar collector and
have a few questions.

   The first is aluminum or fiberglass. At first it seemed to me that
fiberglass would be OK as the thermal distances are so very short. Now I
  wonder if  there aren't other considerations. Certainly the aluminum
screen is thicker and perhaps denser. I notice for Gary's solar barn
article that he used aluminum.

   The second is that screen seems to be rated by "mesh", anyone got a
clue as to that? Of course, I may have no choice n what is available!

   I'm looking at this:

as I only get short lengths of black aluminum locally.

  I finaly got hold of a hard copy of this months Mother Earth News,
Gary's Solar Barn looks good in print. There's also a quickie review of
some of the commercial collectors. Of note is Morris Dovey's collectors
and the Cansolair. No mention of Bill Kreamers shop...

Hi Jeff,

As you say, I used the black alum screening.  It was from Lowes -- you might try
them if there is one in the area.  As I recall they had 30 ft rolls and 100 ft

I think that you probably want two layers.  I measured 3 side by side bays with
1 layer, 2 layers and 3 layers of screen.  The 2 and 3 layer did about the same
-- both significantly better than the 1 layer.

It seems like separating the two layers by a small space might also be a good
idea -- I did not do this, but it seems like it might work better.

I  think that the fiberglass might work OK as well.

I've received some good feedback on the MEN article -- it would sure be nice if
someone were up for trying the integrated in the wall version for a finished
living space.  I think the incremental cost per sqft of this kind of collector
could be very close to zero!
