color=#0000ff size=2>The thermal test was undertaken in 2008 (reported
2009) in BBA labs in the UK. The panel was 490 mm thick and 3.4 m high
x 3.5 m wide with two layers of approximately 30 mm thick hydraulic lime
render on both faces. the bales were laid flat (as standard) and the bale
density was approximately 130 kg/m3 after compression inside a timber frame. the
test was a steady state guarded hot box arrangement undertaken in accordance
with BS EN ISO 8990:1998. I will need to check with partners who sponsored the
work before releasing the report in full, although I don't expect it will be a
problem.</FONT></SPAN></DIV>

<DIV></DIV>Hey Rob,
<DIV>I took off 1" stucco on each side (at R 0.2/inch) on both sides and came up
with R 1.75/inch for the bales themselves. Still better than the R 1.25/inch
that is listed in the 2007 PHPP. </DIV>
