I have " domestic insulation" over 2 in of ceramic insulation. The 2 in of ceramic more than drops the heat before it gets to that layer . You should be good to go with 3 ins. Forget the pearlite cement layer now and drying should be easy.
For anyone reading this rockwool fiberglass domestic insulation can not be used as the primary insulation in an oven . But as a secondary it works but it must have a high temp insulation layer to protect it
