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, spread of flame and smoke emission, toxic gas emission, flaming droplets/particles and/or a combination of these safety aspects.
A1 is the best classification. A1 products do not contribute to the development or spread of fire. They generate neither smoke nor flaming droplets.
Most ROCKFON ceilings are rated A1.
