Fire Retardant Plywood

Regency Fire Retardant Ply conforms to requirements of IS:5509. It is treated with special fire retardant chemicals such as diammonium hydrogen phosphate, at the time of manufacture. The addition of fireproofing chemicals, gives the plywood better fire proofing qualities such as,

  • • Lesser tendency of spark and ignite
  • • Slow burning, having a decreased tendency for fire to spread over the surface of the plywood
  • • Low flammability
  • • Lesser smoke generation
  • • Higher flame penetration time

Thickness usually ranges from 4 mm to 18 mm, while standard size sheets such as 8' x 4' are commonly used.
