What are Fire Resistant Floors and Walls?

Fire resistant flooring and wall systems include properties that are resistant to fire and will not structurally fail for a specified amount of time. These can be differentiated based on ASTM Methods.


Standard Tests for Fire-Resistance

Floors:

ASTM E648 – This is the standard test method for critical radiant flux of floor covering systems using a radiant heat energy source. The critical radiant flux of the flooring is determined by igniting it to see how far the flame spreads prior to self-extinguishing. The higher the number, the better the fire resistance. A Class 1 fire rating requires the number to be greater than 0.45 W/cm2.

ASTM E662 – This is the standard test method for specific optical density of smoke generated by solid materials. The optical density is determined by the smoke generated when a sample is ignited. The lower the number, the better the fire resistance. Class 1 requires less than 450 Ds but can vary by local requirements for certain areas (means of egress, etc.)

Walls:

ASTM E84 – This is the standard test method for surface burning characteristics of building materials. This tests the flame spread and optical density of smoke generated for building materials. Class 1 requires below 25 for flame spread and below 450 Ds for smoke generation.

Benefits of Fire-Resistant Floors and Walls

Fire resistant flooring and wall systems reduce the spread of flames and smoke in the event of a fire-related incident within a facility.

Benefit highlights include:

  • Reducing the spread of flames and smoke throughout a facility or area
  • Providing greater protection of people and property during a fire-related accident/incident
  • Gaining peace of mind/security against careless actions (e.g. the discarding of lit cigarettes)

Recommended Industries

Nearly all industries benefit from the installation of fire resistant flooring. In fact, most facilities require it.
