Vermiculite exfoliée. Le procédé d'exfoliation est réalisé commercialement en faisant passer, d'une manière contrôlée, la vermiculite brute dans la chambre d'un four. Sous l'effet de la chaleur, la vermiculite se dilate à angle droit par rapport aux plans de clivage, produisant des particules en forme d'accordéon d'un volume égal à plusieurs fois leur volume original. 7, record 1, French, - vermiculite%20exfoli%C3%A9e

I am 90% complete with an 8'x8' outdoor sauna. It's really a garden shed with an old wood burner in it. It's cedar-lined with very little insulation.
