Interior Finish Flame Spread Classification and Fire Protection for Decorative Materials

Achieve a Class A Fire Rating with No-Burn

Rating a material’s flame spread lets specifiers, architects, designers and inspectors know what to expect in the event of fire. These ratings rank materials based on how rapidly the flame spreads and smoke is developed. No-Burn actually stops the spread of flame, hence the Class A or Class 1 designation.

Fire ratings are required in all building types and are often classified as interior finishes in commercial, retail and institutional settings.

Flame spread classifications are developed using the American Society for Testing and Materials (ASTM) “tunnel test.” Class A fire ratings indicate flame-spread of 0-25 and smoke developed between 0-450 and is the highest of the ratings. The Class A or Class I rating indicates superior fire protection.

Fabrics used in these building types are also required to be flame retardant. The applicable fire protection standard for curtains, draperies, fabric hangings and similar combustible decorative materials suspended from walls and ceilings is National Fire Protection Association (NFPA) 701, measuring the flammability of a fabric.

No-Burn fire protective coatings provide a Class A interior finish, or Class I flame spread and smoke developed classification, and exhibits improved fire performance in accordance with NFPA 701 when applied to specified substrates.
