SIMOND STORE 0.47″ Ceramic Fiber Board (12×24) – 2300°F

This aluminosilicate refractory fiber board is rated for up to 2300°F, making it suitable for near-vent areas around wood stoves and other heat-intensive installations. It measures 0.47 inches thick and 12 by 24 inches, with a density range of 20-24 lb/ft³. Key specs include a 78 PSI compressive strength at 25% deformation, a maximum permanent shrinkage of 3.5% at 2200°F after 24 hours, and LOI of 4-7% at 1832°F. These properties help maintain barrier integrity under prolonged heat exposure.
SIMOND STORE 2300°F Ceramic Board (1″ x 18″ x 24″)

This 1-inch-thick ceramic fiber board delivers robust high-temperature insulation for wood stoves, fireplaces, and related equipment. It supports temperatures up to 2300°F (1260°C) with a density of 20-24 lb/ft³. Its spec sheet lists 78 PSI compressive strength at 25% deformation, 3.5% maximum permanent shrinkage at 2200°F with 24 hours soaking, and LOI of 4-7% at 1832°F. A versatile size for slightly larger panels and more aggressive heat shielding.
SIMOND STORE 2300°F Board – 1″ x 15″ x 24″ (Pack of 2)

This paired pack provides two 1″ thick boards sized at 15 by 24 inches, ideal for extending heat shields or creating larger protected stretches around wood stoves. Rated up to 2300°F with a density of 20-24 lb/ft³, the product maintains similar performance to single boards, including 78 PSI compressive strength at 25% deformation, 3.5% shrinkage at high heat, and LOI between 4-7% at 1832°F.
SIMOND STORE 0.5″ Board – 19.7″ x 39.4″ (1/2″ Thick)

With a 1/2-inch thickness, this long sheet targets larger wall sections or floor protection under stoves. It keeps heat within safe bounds up to 2300°F, maintains a density of 20-24 lb/ft³, and shares the same mechanical properties as other boards—78 PSI compression strength, 3.5% maximum shrinkage at 2200°F with prolonged heat exposure, and LOI of 4-7% at 1832°F. It’s suitable for multi-panel installations or cutting to fit curved or irregular spaces around a stove.
SIMOND STORE 0.47″ Board – 18×24 (Alternative Size)

This 0.47-inch thick board offers a compact option for tight clearances around stoves. It maintains the 2300°F rating, 20-24 lb/ft³ density, 78 PSI compressive strength, and 3.5% shrinkage at high heat. LOI remains at 4-7% at 1832°F, providing reliable barrier performance where profile space is at a premium.
SIMOND STORE 1″ x 23.6″ x 35.4″ Board

This large-format board is designed for substantial wall coverage around wood stoves and is rated up to 2300°F with the same high-density composition. It offers 78 PSI compressive strength at 25% deformation, 3.5% maximum shrinkage after extended heat exposure, and LOI of 4-7% at 1832°F, making it a robust choice for extended installations or custom paneling projects.
Plexon 32×28 Thermal Stove Board – Wall & Floor Protector

This product serves as a durable heat barrier for both walls and floors near stoves. Built from non-combustible materials, it is suitable for wood stoves, pellet stoves, and other heaters. It also functions as a versatile protector against scratches and heat damage, with broad compatibility for kerosene and gas stoves, electric heaters, and fireplaces. While not a traditional fiber board, it provides a reliable alternative for high-heat protection in tight spaces.
Buying Guide
Key considerations when selecting fireproof wall panels or boards for wood stoves:
- Temperature rating: Look for boards rated at 2300°F (1260°C) for near-heat zones; this ensures long-term performance around most wood stoves and ovens.
- Thickness and density: Thicker boards (1 inch) offer greater insulating capacity; denser boards (20-24 lb/ft³) resist deformation and cracking under heat.
- Compressive strength: A higher PSI rating indicates the panel will resist crushing under contact pressure or mounting hardware.
- Shrinkage and LOI: Low permanent shrinkage (around 3.5%) and a moderate LOI (4-7%) help maintain barrier integrity after prolonged heat exposure.
- Size and cut-ability: Panels must fit existing wall dimensions or be easily cut with standard tools. Consider modular boards for easier customization.
- Installation considerations: Ensure mounting methods accommodate heat exposure; use non-combustible adhesives or mechanical fasteners recommended by the manufacturer.
- Compatibility: Check whether boards are designed for use behind stoves, fireplaces, kilns, or baking ovens, and select the best fit for your setup.
- Cost and availability: For larger installations, plan a combination of standard sizes to minimize waste and simplify installation.
Performance perspectives:
- Dedicated ceramic fiber boards offer superior heat resistance and light weight, facilitating easier handling and installation in tight spaces.
- Baffle boards from manufacturers like Lynn Manufacturing provide a rigid, heat-tolerant alternative for direct stove interior use, especially when shield panels are in question.
- Protective stove boards that double as wall and floor protectors help simplify spaces where heat and impact resistance are both required.
Installation tips:
- Measure accurately, then cut boards to fit gaps without forcing panels into tight spaces, which could crack or warp.
- Seal edges where possible to reduce air gaps that could transfer heat toward interior walls.
- Follow manufacturer guidelines for fasteners and adhesives; use non-combustible joiners in high-heat areas.
- Inspect periodically for signs of wear, cracking, or loosening, especially after heating seasons.
