Others have gotten good results with the primary
conductor directly in contact with wood or particle
board, but I'm not comfortable with the idea.  Wood
products are OK for a primary deck foundation, but not
for insulation.  Use plastic, glass, or ceramic stand
offs of some sort so the copper tube isn't in contact
with wood.  I used PVC pipe insulators.  It was cheap
and effective.  Have a look at the world's simplest,
cheapest spiral primaries at:
