What is fire class A1 vs A2

When it comes to fire safety, understanding the different fire classes is crucial. In particular, fire classes A1 and A2 are commonly mentioned in the context of building materials and construction. But what do these classifications actually mean? Let's delve into the specifics.

A1 Fire Class: The Gold Standard

Fire class A1 signifies materials with the highest level of fire resistance. These materials are non-combustible, meaning they do not ignite or burn when exposed to flames. They also do not release any significant amounts of heat during combustion and produce no smoke or toxic gases that might endanger occupants.

Typical examples of A1 class materials include cement, concrete, bricks, and metals such as steel. These materials have been extensively tested and proven to meet rigorous fire safety standards based on their excellent performance in laboratory experiments and real-life fire situations.

A2 Fire Class: High Level of Safety

A2 class materials, although not entirely non-combustible like A1
