I need 12' to simplify things but that doesn't look like a problem. I
was thinking about steel or fiberglass but PVC may be lighter. This
looks like a possibility too. Clear would allow me to see the
critters under there. We have squirrels making a nest in our gas
grill (hasn't been used in years) now. I wouldn't want them under
there.

Pvc can be heavy, could try Polycarbonate Twinwall if you want some
what clear.

Yikes! That's some expensive stuff! More than $4000 for the 12x16
deck.

The stuff I saw is here, not quite 4 grand either

Better, but still $800 ($500 shipping). How do the panels join with a
watertight seal?
They sell that stuff, basically a batten held down by screws with
weather strip gasket. Getting on top to do the work might not be the
easy though. Hiring a basket truck might increase cost a wee bit.

Basket truck? To attach the panels to the bottom of the joists of a deck?

I'm pretty sure his deck isn't that high off the ground.
