A Level vs Class A Fire Rating What Specifiers Need to Know
Fire rating classifications for flooring vary by country and standard. Specifiers working on international projects need to understand the differences. This guide explains the main classification systems and how SWF meets them.
European Classification A Level
The European system uses A through F classification. A level is the highest. Materials classified A level do not contribute to fire development. They self extinguish when the flame source is removed.
SWF achieves A level classification under this system.
North American Class A
The North American system uses Class A, B, C. Class A is the highest. It is determined by flame spread index and smoke development index. Class A requires flame spread under 25 and smoke development under 450.
SWF meets Class A requirements for North American projects.
Why Fire Rating Matters
Flooring fire rating is specified in building codes based on building type and occupancy. Exit corridors, public assembly areas, and spaces with limited egress require higher fire rated materials.
Specifying the correct fire rating is essential for building code compliance and occupant safety.
