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

[Gennaro Brooks-Church - Eco Brooklyn]

John: " In my case a foam brand is about 60 miles away "

I doubt that. If it is like most products on this planet, it's ingredients
span across all continents: soy from Nebraska, ingredient A from China,
Ingredient B from the Philippines, canisters from Mexicon etc.

This the argument for simple building materials. Less ingredients, less
travel. Cob: hay and mud from next door. Now that's green.
