Default Re: Waterproofing the blanket

Talisker63

The aluminium foil in Rado (and others) oven is just to permit free movement between the different layers with different thermal expansion ratios, like the refractory bricks and the cladding.
You would not like any foil over your blanket, just chicken wire to fix the cladding.
The secret in structures with big temperature variation is to maintain the characteristics of each layer as closed as possible from the adjacents ones.
So, the blanket over/under the vermiculite isolation is going to work not only as more isolation as separation between layers.
There will be not a problem that the blanket be wet, you just will need to fire your oven from small to higher fires, how was explained around this forum.
