[Greenbuilding] Foam insulation advice needed

[Steve Houlihan]

Bobbi,

Please note that LEED does not certify or recommend products.  If you 
read the letter on Demilec's website carefully you will note that it is 
written by Demilec and it only suggests that their product can be used 
to help achieve LEED points.  If you use enough of their product (or any 
other) to get insulation performance at least 12% above baseline, then 
you get one LEED point.

Although their documentation is very thorough and accurate, it is very 
slightly misleading.

Their product looks very similar to Icynene which I used in my home.  I 
am very happy with it and noticed no smell or ill effects after all the 
airborne particles had fallen.  This was only a few minutes but once 
they are on something the only solvent that works in sandpaper!
