Juvale Insulation Foam Board Sheets
The Juvale foam board sheets are designed as a Creative Foundation for various projects. The 11 x 17 inch sheets come in a 1 inch thickness and are sold as a 6-pack, offering a versatile base for both foam insulation applications and crafts. Their durable construction supports intricate designs and detailed artwork, making them well-suited for sculpting, diorama backgrounds, and craft blocks. The smooth, paint-ready surface provides vibrant results when painted or coated, enabling precise detailing for model builds or display pieces.
BXI Ceramic Fiber Thermal Insulation Board
The BXI ceramic fiber board is a high-temperature, inorganic insulation option. With a 12″ x 8″ base and a thickness of 0.4″, it offers an impressive maximum use temperature of 2732°F (1500°C) and a class A1 fire resistance. Its inorganic composition provides higher R-value and durability with reduced smoke and odor compared to organic ceramic fibers. This makes it suitable for heat-intensive modeling contexts or demonstrations where flame resistance and thermal performance are priorities.
Silverlake 11x17x0.5 Craft Foam Boards
These Silverlake craft boards are described as professional-grade, dense, and rigid, designed for precise work. Made from high-density EPS foam, they can be sanded, shaped, and painted, making them compatible with water-based paints and sealants. They cut cleanly with a hot-wire knife, which is ideal for detailed diorama backgrounds, architectural model bases, and scenic design for presentations. The boards are durable for repeated handling and layering in complex builds.
Silverlake 11x17x1 Craft Foam Boards
These Silverlake boards offer a full inch of rigid foam, enabling thicker construct designs and stronger base structures for models and dioramas. The professional-grade EPS composition supports layering and detailing, while maintaining a smooth surface ready for coatings. They are suitable for multi-step builds that require height and stable foundational elements, with compatibility for both paint and sealants to achieve durable, display-ready results.
White Foam Boards 8 x 10 – 10 Pack (KICPEG)
This pack provides ten 8 x 10 inch boards with 3/16 inch thickness, delivering a premium white surface ideal for school presentations and craft projects. The polystyrene foam core is easy to cut and customize, with a matte surface ready for screen printing, glue, paint, or markers. The boards are designed to be durable and easy to transport for classroom or hobbyist use, supporting quick setup and repeated display building.
Mat Board Center, 11×14 White Foam Boards
The Mat Board Center pack offers 10 acid-free 11 x 14 inch boards with a 1/8 inch thickness. The acid-free composition supports long-term display and reduces the risk of degradation over time. These boards are well-suited for professional presentations, framing, or gallery-quality displays where archival quality and clean edges matter for a refined finish.
Buying Guide
- Intended use: For high-detail model work or dioramas, choose denser EPS or inorganic boards (like the Silverlake and BXI options) that resist denting and allow precise shaping.
- Surface and coating compatibility: Ensure the board surface accepts acrylic, water-based paints, or adhesives without warping. A smooth, paint-ready surface is beneficial for clean color applications.
- Thickness and rigidity: Thicker boards (1 inch) offer stronger structures for multi-layer builds, while thinner boards (1/8–3/16 inch) suit flat displays and light dioramas.
- Fire resistance and temperature tolerance: For projects involving heat or high visibility displays, inorganic boards with high thermal resistance provide safer operation and longer life.
- Acid-free and archival considerations: If the display is intended for long-term storage or gallery use, acid-free foam cores reduce deterioration over time.
- Ease of cutting and finishing: Boards designed for hot-wire cutting and clean edges save time on shaping and detailing, especially for intricate models.
- Cost and availability: Consider pack sizes that match project quantity to minimize waste and simplify procurement for ongoing projects.
- Storage and handling: Rigid boards are best stored flat in a dry environment to prevent warping—particularly larger sizes like 11 x 14 or 11 x 17.
