in that case the triangle has way more surface area (and overall mass) but no airspace. you're saying the panel is more efficient? is there data to support this?
thanks.

I'm not the one to quote data...as I am certainly no expert. But it's been my understanding that air space behind bass traps is effecient. And in saying
effecient, purhaps I should have said
cost effective. As in, the return on investment of filling a corner completely is not equal to the efficiency of using the same amount of insulation to
straddle more area.
Glenn or Ethan please correct me if I'm wrong.
