Just poles and purlins? How about 1" "R6.8" double-foil polyiso board?
Around Phila, 4'x8' sheets cost about $16. With air gaps, the foils add
about R3 to each side. You might glue square 1x3 spacers to the back with
gobs of spray foam from a can, let that harden, then stick the board to
the inside of the metal siding with more spray foam and foil-tape the seams.
For more cheapth, you might screw 2"x4" welded-wire fence to the inside of
the poles with 1x3 cap strips and fill the 6" space between the fence and
the siding with plastic bags containing dry leaves.
Then add Gary Reysa's $350 160 ft^2 solar barn heater, described at
http://BuildItSolar.com and in the Oct/Nov issue of Homepower magazine.
You maybe store solar heat in thermal mass under a foil ceiling.

| Dried leaves, ha, ha funny, boy. I'm cheap, but not that cheap. I'm just
looking for something less expensive than the $7500. I was quoted for the
closed cell spray on insulation I was looking into.
Dried leaves, where am I supposed to get them, it's wetter'n hell here.

Funny you should mention this stuff. I just put three sheets of it on the
inside of my garage door. Just cut to fit into the panels and used
'construction adhesive' to attache the un-foiled side to the inside metal of
the door panels. Figure between the foam and foil, should help keep the
garage warmer. Don't deliberately heat it often, but with two car's worth
of engine heat, it used to melt the snow off the car windows by morning most
days. Hope with this foam (before was just uninsulated tin door), and the
adjustments I made to reduce the draft around the door, it will be warmer
this winter.
$15.97 at Lowes for 4x8 1" polyisosomethingorother. While one side is metal
foil, the other is just 'sealed' with a plastic material.

Home Depot and Lowes sell foil-1-side, but you can get it with 2 foils
for about the same price from building supply places and save more heat
that way if 2 airspaces are possible. One double-foil brand is Atlas
Energy-Shield roof insulation.
