Reaction to fire
Reaction to fire determines whether a material fuels a fire
The EU Reaction to Fire evaluation criteria (EN 13501-1) measure a material’s ignitability, rate of heat release, rate of spread of flame, rate of smoke emission, toxic gas emission, flaming droplets/particles and/or a combination of these safety aspects.
A1 is the highest classification. A1 products do not contribute to the development and spread of fire. They generate neither smoke nor flaming droplets.
Most ROCKFON ceilings are rated A1.
