Looked into building a house out of EPS panels, since it (at first look) looks like a splendid material with built in insulation. However:

1: it loses its integrity around 80-100c causing catastrophic failure on bearing capability

2: it burns literally like any other hydrocarbon, and its foamed construction makes it highly flammable

3: to reduce flammability and adhere to code you need to use EPS with flame retardants - which fuck you up, you're basically building a house out of Frozen gasoline and flame retardants.

so if you want to go this route, take a look at Corkwood instead - comes in large industrial panels and can be used to build houses - been used for 100s of years, doesn't burn - at-all - and contains no nasty shit.

For completeness sake: --------------

so next house is going to be made from Poroton instead: https://archello.com/product/s9-p-climate-neutral-poroton-br...

reasons: Easy to build, integrated insulation and loadcarrying in same simple structure, and (this is the mayn reason why instead of foamed concrete) it is permeable, meaning that you do NOT need active ventilation system (Causing dryair in winter etc.) and air moisture is constant year round.

you coat it with a silicate based coating on both sides (also permeable), and nothing else. The result is a breathing house, that is net-zero, you can even build your bathroom from that stuff and it will just wick moisture from the air and slowly release it again.

wonderous stuff.
