Fireproofing Around a Kiln

Short answer: No, you cannot place a kiln near non-fireproof surfaces.

1. All surfaces within 3 feet (36", .91 Meters) of the kiln must be fireproof.
2. If non-fireproof surfaces are present, cover them with cement board to make them heat-resistant.
3. Cement board (available in 4' x 8' sheets at hardware stores) is commonly used under tile floors and walls. The thicker, more rigid type is best.
4. For walls, leaving a 1" gap behind the cement board significantly improves heat protection.
5. For floors, a double layer of cement board works best, as leaving a 1” gap is impractical. The boards should extend at least 12" beyond the kiln’s footprint.
6. To improve appearance, you can cement tiles over the board.
7. Cinder blocks can also be used under the kiln for additional protection, as seen in this photo.
