I know this has been discussed, and I've tried to read all the posts describing the recommended refractory concrete dome cladding. I've priced the KS-4+ castable refractory available locally, and it'll be several hundred dollars to clad the dome. I'd previously decided to invest more heavily in CF blanket and board insulation, which is also expensive. I'm looking to reduce the cost to finish the oven build itself, and am wondering if there's a way to use regular sack mix, and still have an intact, efficient barrel-type oven a couple decades down the line. I'm planning a 2-3" cladding layer, over foil, over the dome firebrick. I'll insulate the clad dome as heavily as I can afford, using a combination of board and CF blanket. Hearth insulation will be at least 4" of FBX1900 board insulation, "rigidized", to reduce any issues with moisture down the road. I'd appreciate opinions from the many of you that've used other than refractory cladding, and what your thoughts are now that you've been running your ovens for a while. Can I use any portland cement product, or after all this, is it foolish to substitute for the refractory castable.
Thanks very much.
Thanks very much.
