being curious about the technique and the hardware. Southern Glass
said that there was somebody in Indianapolis who could do it for me.

Thanks, Michael

That spacer you are talking about is the adhesive and dessicant. Comes
in rolls of various thicknesses. The black stuff is silicone. We often
install at 3000' higher elevation than we build them. We install a
capillary tube to equalize the pressure and pull it out at the installed
elevation.

In my neck of the woods only a flexible spacer is used on curvy stuff.
Aluminum spacer bars for everything else. The bars are 3/8" wide and
3/8" tall and generally one bar is half filled with dessicant to
absorb any moisture trapped between the two pieces of glass. Hot butyl
is then applied with a squeeze gun to the edge of the unit. If stained
glass goes into the unit then neoprene block are inserted into the
butyl at the bottom of the unit to prevent the unit from pushing the
spacer bar into the butyl.
