Pragati fire retardant plywood is an excellent fire-retardant plywood with extremely good resistance capacity from fire. This special grade is treated with proven fire retardant chemicals at the time of manufacture and completely composed with high density hard wood veneers. With boiling water proof marine grade quality standards, Pragati fire retardant plywood is uniquely processed for creating a super resistance from fire. We manufactue fire retardant plyas per IS:5509 specifications that ensures the flammability test, rate of burning and flames to penetrate in plywood as per the Bureau of Indian Standards
Pragati f.r.p. is advisable to be used in public places, where the risk of fire has to be reduced. The areas such as in kitchen woodwork of large restaurants, interior woodwork public auditoriums, theatres and banquet halls.

Pragati f.r.p. is the best product for any interior wood working, specially at such places where the risk and spread of fire has to be reduced. It resists Spark and Ignite without any penetration. It offers 30 % lesser smoke generation with extended flame penetration time. It offers very Slow burning, having a decreased tendency of the fire to spread over the surface of the plywood.
