Obviously there are a variety available - wood-chip type (Durisol & Velox), EPS (Virtually all of them it seems), XPS etc etc. so far i've only seen one (POlarwall) which uses XPS. Why do we think this is? 

 

Am I correct in thinking that measure for measure it is a better insulator than EPS?

Also doesn't it generally speaking have better strength characteristics?

I like to give evidence-based answers. This isn't.

Durisol incorporates insulation within it. In the terms you ask '.... measure for measure...' I am certain that when I stopped researching the issue ( For any given thickness of wall, is Durisol better at insulation than  comparable technologies? ) , there are (or were) some comparative tables.  I remember being distinctly skeptical about how the comparisons were done. The author wasn't identified, and neither was the organisation that funded the production of the table.

 

In terms of its strength: better than EPS, or than other wall construction methods?

Durisol use a specialist SE: give them a ring and ask for his (it is a bloke) contact details.

durisol uses PIR insulation in their blocks .

  look at the different insulation values of the different types of foam .and you will then  see the differences in thickness you need  of a lesser foam to get same insulation value as PIR
