Fire Retardant Plywood

Fire-retardant plywood manufactured and treated to resist flame penetration and slow heat transfer. Available in standard 2440 × 1220 mm (approximately 4' × 8') panels in 12 mm and 18 mm thicknesses, these panels are intended for interior applications where reduced flammability is required without compromising structural performance.

Typical construction meets established manufacturing practices for FR plywood (multi-ply construction, selected core species and treated veneers). Panels are supplied in factory-treated format and must be stored dry and handled per manufacturer guidance. Independent laboratory testing and certification are available for verification of fire performance and dimensional/physical properties.

Specifications

• Panel Size: 2440 × 1220 mm (nominal) — standard 4' × 8' equivalent
• Thickness Options: 12 mm, 18 mm
• Grade / Type: Fire-Retardant plywood — FR grade (Type 1 / treated veneer method as per IS requirements)
• Typical Construction: Multi-ply laminate (factory treated); face & core veneer species vary by mill
• Density / Moisture: Manufactured and tested to applicable limits (see lab reports)
• Finish: Sanded — ready for paint/laminate or further fabrication

Fire Performance & Testing

• Certified / manufactured to Indian Fire-Retardant plywood requirements (IS 5509).
• Independent IS 5509 test report available (sample evaluation / dimensional & workmanship checks).
• Manufacturer TDS indicates compliance with flame penetration and flammability criteria per IS 5509 (passed in laboratory tests for 18 mm FR product).
• Where available, ASTM E84 (surface burning) testing for 18 mm fire-retardant panels shows Flame Spread Index (FSI) 55 and Smoke Developed Index (SDI) 60 for the tested configuration — use these numbers for project approval and code comparisons where ASTM/UL data are accepted.

Applications

• Interior wall linings and ceilings in commercial and institutional buildings
• Partitions, joinery and fixtures where enhanced fire performance is required
• Fit-out works for hotels, offices, retail and transit areas subject to local fire code controls
• Pre-fabricated panel systems and non-structural interior components

Storage, Handling & Installation Notes

Store panels flat, dry and off the ground. Protect from prolonged exposure to moisture — fire treatment is not a substitute for waterproofing. Cut edges should be finished or sealed as recommended by the supplier. Install per relevant building code and substrate/fastener manufacturer guidance. For applications subject to specific code approval, provide the project authority with the relevant test reports and certification documents cited in this product information.

Quality & Certification

These fire-retardant panels are produced under documented manufacturing and treatment processes and are supported by laboratory test reports and a BIS/IS certification licence where indicated. Always request batch-specific test documentation and the certificate of conformity for critical projects.
