Class A Fire Resistance
Class A fire resistance is the highest rating for a roofing material in terms of fire protection. It means that the roofing material is able to withstand severe exposure to fire originating from sources outside the building. Class A roofing materials are typically made from non-combustible materials, such as concrete, metal, or asphalt shingles. Here are the requirements for a roofing material to be classified as Class A:
- The flame spread index must be 0 to 25.
- The smoke developed index must be 0 to 450.
- The total heat release must be 150 to 300 watts per square meter.
- Concrete roof tiles
- Metal roofs
- Asphalt shingles with a fire-retardant coating
- Fiberglass shingles with a fire-retardant coating
- They are more resistant to fire than other types of roofing materials.
- They can help to prevent the spread of fire.
- They can help to protect your home from smoke damage.
- They can help to reduce the risk of injury or death in the event of a fire.
