[Greenbuilding] embodied energy was Polyiso strength on roof (ErgoDesk)

[John Salmen]

So if diverting energy from the food stream and the deforestation that results is unacceptable in the case of soy foams – why is diverting energy from the paper stream and subsequent deforestation of NA acceptable?  The question is density and the amount of a virgin material used to get a result – and then the question becomes appropriate virgin material.  I don’t like bringing food material into the building or waste stream but it may be better than producing synthetic material – I don’t know?.  

 

All insulations are simple – a material that is made to encapsulate air. . Cellulose or fibre material is odd because we are harvesting, processing and transporting a coarse material that either naturally encapsulates air or is made to do so rather than simply introducing air into a material in a geographically more local context – and most foams are produced close to the regions where they are marketed. In my case a foam brand is about 60 miles away whereas mineral wood is about 3000 miles.

 

Again not a defense of foam just trying to make sense of the discussion.

and that 5% that is soy has the carbon of the fertilizer and fuel it took to grow, harvest, transport, and process it. I would not doubt that is a greater EE factor than pure plastic. 

 

not to mention, the diversion from feedstock. IOW's, how many more acres of Amazon forests does it take, to grow feedstock for raising cattle, because of the soy that was used for manufacturing insulation?

put another way, could you eat your insulation if you got hungry enough?

They tell me it's made from soybeans and pop bottles so it must be good.

A whopping 5% of the foam is soy. The other 95% is just like any two part foam. Last time I checked.
