Fire Retardant Plywood

STONIC is a 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, STONIC FRP is uniquely processed for creating a super resistance from fire. STONIC FRP is manufactured as 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. STONIC FRP 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. STONIC FRP is very suitable for every application in premium homes and villas as it confirms to all requisites of IS 710 and IS 5509. It can be used in railway compartments of railway trains or other public transport or station facilities. STONIC FRP is the most suitable plywood panel for high rise commercial buildings as this will prevent the occupants From fire and fumes for an extended period of time to provide enough escape time. STONIC FRP is the best product for any interior wood working, specially at such places where the risk and spread of fire has to be reduced.

STONIC FRP 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.

USES: Ships, Bus coaches, Cinema Halls, High rise buildings, Restaurants, Railway Coaches, Vehicle Bodies in Boiler House, Kitchen, Inner Roof Wall Linings, Exhibition Stalls, Public places, Offices, Homes etc.

As per 5509:2010 and IS 15061
