LTW + Zeroflame - Technical Specification

In the adverse event of a fire, Sonear LTW+ Zeroflame Retardant Plywood delays the spread of fire due to its chemically treated slow burning properties. The low flammability, low rate of burning and higher flame penetration time provides “Safety” and “Comfort.”
