Hello, I am building a passive house in France. Initially i was going to use Durisol, then I found Isotex. The reason I chose a heat treated wood based ICF was because there are Termites on the land and although they don't eat Polystyrene they can burrow into it. As far as I have been able to find out, the differences between the two blocks are as follows:- 1) Isotex is a denser block i.e. more wood chips are pressed to form it than is used to make Durisol. 2) The concrete infill on Isotex covers the joints so helping with airtightness. 3) Durisol is sold by the pallet so you may have to buy more than you actually need. You send your plans to Isotex and they work out what you need. I have contacted Isotex in France and Italy. they are a bit snooty and like talk to my architect rather than me.
