People expect their homes, work places, schools and hospitals to be safe. Fortunately, fires are rare, but when they strike, they can be disastrous. A1 rated materials, the safest classification a product can achieve, do not contribute to the development and spread of fire and buys valuable time for occupants to safely evacuate the building.
What happens in a fire?
A fire is always the result of an ignition source (heat), oxygen (air) and the presence of a combustible material. Oxygen and combustible materials are necessary to nourish and spread a fire. By using as many non-combustible materials as possible, the risk of fire and smoke will be limited or better contained. The determining factor of whether a small fire spreads is affected by how the surrounding materials react to fire.
Where there is fire there is smoke
As a fire burns, the combustible materials in a room release toxic smoke. The amount of toxic smoke released depends on the amount of combustible material in that particular space. In high enough concentrations, toxic smoke creates hazardous health conditions. In fact, toxic smoke inhalation causes more fire-related deaths than do the flames themselves.
Identifying combustible materials
To help identify combustible materials and increase fire protection, various national regulations have adopted minimum targets aimed at reducing the spread of fire. One of those tests a material's reaction to fire.
Reaction to fire
Reaction to fire determines whether a material contributes to a fire. The “Reaction to Fire” classification (BSEN 13501-1) measures a material’s combustibility, the rate of heat release, the rate that flames spread, the rate of smoke emission, flaming droplets/particles and/or a combination of these safety aspects.
A1 is the safest classification a product can achieve. A1 products do not contribute to the development and spread of fire. They generate neither smoke nor flaming droplets. Most of our products are classified as A1, meaning they do not contribute to a fire.
Certain Rockfon ceilings can be used to provide fire resistance up to 60 minutes. When installed with specific grid and clips they can create 30 minutes’, and some can create 30 and 60 minutes’ fire resistance in accordance with BS 476 Part 21 and Part 23. Please contact our Technical department to discuss your requirements.
Most of our ceilings are rated A1, meaning that they do not contribute to a fire. Only a non-combustible product can be rated in the safest class A1. Explore our range of products that do not contribute to a fire.
