Maasechs 24x15x3/4 Insulation Board
This ceramic fiber board is rated to 2300°F with a high density of 16 PCF, providing reliable thermal insulation. The board measures 24 by 15 inches and is 0.75 inches thick. It is formulated to resist expansion when heated, helping maintain its shape and insulation properties during use in ovens, kilns, or fireplaces. Its dense composition supports stability under repeated heating cycles, making it suitable for pizza oven projects requiring a durable panel with consistent heat retention.
Lyrufexon Ceramic Fiber Insulation Blanket
The Lyrufexon insulation blanket covers 24 by 15.7 inches with a thickness of 1 inch and is rated for up to 2600°F. It is designed for direct flame exposure and is positioned for use in wood stoves, fireplaces, pellet stoves, chimneys, furnaces, boilers, pizza ovens, and for forge work. The broad applicability makes it a flexible option for varied oven designs and retrofit projects, offering strong fireproof performance and straightforward handling for customized shaping.
Amylove 2 Pcs Ceramic Fiber Insulation Blanket
This set includes two high-density ceramic fiber blankets sized 60 by 24 inches with a thickness of 1 inch, rated up to 2600°F. The blankets are suitable for stoves, kilns, forges, fire bricks, boilers, and pizza ovens. They can be cut to fit project dimensions with common tools such as scissors, enabling flexible installation for custom oven enclosures or lining. The material emphasizes fire prevention and insulation, providing practical versatility for metalworking and home baking setups alike.
SIMOND STORE 0.47″ x 12″ x 24″ Insulation Board
This 0.47-inch-thick board measures 12 by 24 inches and offers a maximum temperature of 2300°F with a density in the 20–24 lb/ft³ range. It provides strong compressive strength at 25% deformation (78 PSI) and maintains a modest permanent linear shrinkage up to 3.5% after 24 hours at high heat. The board’s performance profile makes it suitable for localized insulation in pizza ovens or wood stoves where space is limited, while delivering reliable heat retention and structural resilience.
SIMOND STORE 1″ x 18″ x 24″ Ceramic Fiber Board
This board measures 1 inch thick, 18 inches wide, and 24 inches long, with a maximum operating temperature of 2300°F and a density of 20–24 lb/ft³. It provides substantial structural strength with a compressive rating similar to other SIMOND models and exhibits a maximum shrinkage of 3.5% under prolonged thermal exposure. It is a solid choice when a larger panel is needed to cover a baking chamber or to line a larger oven cavity, balancing thickness and installation practicality for pizza oven builds.
Buying Guide: Key Purchase Considerations
- Maximum temperature and material type: Ceramic fiber boards and blankets are chosen for high heat tolerance (up to 2300–2600°F). Confirm your oven’s heat profile and select a board or blanket that meets or exceeds that requirement.
- Board vs. blanket format: Boards provide rigid surfaces ideal for lining flat panels, while blankets offer flexibility and easier cutting for curved or irregular shapes. Consider your oven geometry and installation method.
- Density and insulation performance: Higher density (e.g., 16–24 PCF) typically yields better thermal retention but can be heavier or less flexible. Match density to your structural needs and weight constraints.
- Dimensions and fit: Measure interior cavity dimensions and seek boards or blankets that can be cut to fit with standard tools. Check thickness when space is tight inside the oven or fireplace.
- Compressive strength and shrinkage: For high-heat cycling, boards with strong compressive strength and low shrinkage reduce gaps and maintain insulation over time.
- Cutting and handling: Some blankets are easily cut with scissors; others require utility knives or saws. Use proper safety equipment (gloves, masks) when handling high-temperature materials.
- Application versatility: If you plan multiple uses (wood stove, forge, furnace, or kiln), choose products marketed as multi-application to simplify future projects.
When selecting insulation for a pizza oven, prioritize stable insulation performance under repeated heatings, compatibility with your oven geometry, and ease of installation. These five options provide a range of formats and specifications to support effective heat retention, safer operation, and durable oven construction.
