Fire-Retardant Ratings for PVC Flooring

The fire-retardant rating of PVC flooring is not a single, fixed value; it depends on the testing standards and the specific product formulation. Common ratings include the Chinese National Standard Class B1 and the US Standard UL94 V-0.

Fire Resistance and Flame Retardancy
High-quality PVC flooring can achieve a Class B1 fire rating, indicating excellent fire-retardant performance-second only to stone. PVC flooring does not support combustion and helps inhibit the spread of fire; it does not emit toxic or asphyxiating gases (according to safety data, 95% of fire-related injuries are caused by toxic smoke and gases generated during combustion).

Rigid PVC Sheets: Fire ratings can reach Class B1 or higher, with some high-performance products approaching Class A.
PVC Flooring: Qualified products can achieve a Class B1 fire rating and possess self-extinguishing properties (extinguishing once the source of the flame is removed).
