So flammable mater + low airflow is somehow more fire resistant than flame resistant mater + low airflow? Looks like the source is pure marketing unless their comparable insulation is perforated cardboard coated in fuel gel.
Roof/attic often uses rockwool or glasswool. Wall insulation is often something like XPS, PIR or PUR.
Although it sounds counterintuitive, I can see straw doused in flame retardant being better than supposedly flame retardant polystyrene foam made from hydrocarbons. I mean, just look at what happened with Grenfell Tower.
“doused in flame retardant” isn’t mentioned in the source as far as I saw, plus it would affect the eco-friendly, workability, cost effectiveness, and biodegradability benefits mentioned (though the last one is worthy of debate as a pro or con in the first place). Everything has its tradeoffs unfortunately. This could be the better side for some surely.
From what I have read they are using a loam layer on both sides of the wall, I doubt that this affects eco-friendliness and biodegradability. And they are F90 certificated. source

lemmy.ml is replacing some of your word with another one. Good ol’ Scunthorpe problem!
