Looks like polystyrene but did it exist then? weighs almost nothing and turns to powder if you touch it. Does anyone know what it is? #wall-insulation

Was an excellent product for additional insulation around the 70s-80s, but unfortunately, it crumbles into powder after a few decades... Additionally, it releases formaldehyde, but it should be down to low levels by now.

Everything except pure wood is probably forbidden to burn? Plastic in particular. Thanks again. Yes, most things are probably forbidden to burn, best to take it to recycling.
