The Fire retardant plywood is composed with high density hardwood veneers that are treated with fire retardant chemicals during the manufacturing process.
Fire-retardant plywood prices are slightly higher than normal MR plywood.
Want to know why?
Well, this is so because it undergoes a chemical treatment that helps it defer flames and delay ignition. Make no mistake, it is not fireproof, only fire retardant.
The plywood is especially useful in areas like the kitchen, cinema theatres, and closed spaces, etc. whereof a fire. It is incredibly useful because upon ignition; it does not emit harmful emissions that can cause breathing difficulty, which helps protect us from fainting, saving us.
Manufacturers make fire retardant plywood with high-density hardwood veneers by treating these individual veneers with fire-retardant chemicals during the manufacturing process.
Who checks if these are “really fire-retardant”?
The Bureau of Indian Standards checks for the safety standard of these plies before they may manufacture these plies on a large scale.
Want to know the best part?
Imagine that the ply caught fire once…. the ply will still have some fire-retarding properties that allows it to delay the second ignition where the time to ignite will not be less than 15t/6min where “t” is the thickness of the fire-retardant plywood.

This treatment makes the plies resistant to extreme fire conditions. They are designed to resist sparks, ignite without any penetration and lower the pace of smoke generation in case of a fire.

They undergo various tests to check regularities like flammability, rate of burning and flames to penetrate the plywood, etc as per the Bureau of India Standards.
Fire retardant plies are advisable to be used in areas where there is a regular use of fire and heat, making it ideal for the kitchen and cooking areas. Using them in public places like cinema halls, shopping malls, restaurants etc ensures safety of the property if there is an accidental fire.
