I pay 24 bucks per 1x 100L bag (3.53 cu-ft), you will need more of them for insulating of the whole oven as per below described quantities.

What is Vermiculite? Insulation applications.

Where to buy vermiculite insulation? Best places to find vermiculite containing products, or most importantly dry loose-fill vermiculite insulation in bags, are large landscaping yards (because in horticulture the vermiculite, as well as Perlite, are used to prevent soil compaction or as soil conditioner/amendment after adding a composting matter.)

You can get regular non organic Brazilian for much, much less. (more…)
