Fire safety has always been a big consideration when selecting wall and ceiling panels for commercial use. While FRP (Fiber Reinforced Plastic) panels are known for their strength, moisture resistance, and ease of maintenance, one key feature differs between the types - fire rating.
The two most identifiable fire classifications in the industry are Class A and Class C FRP panels. For Contractors, architects, or project managers, and others, knowing the difference between the classifications will ensure compliance with code requirements and meet the performance objectives you expect from the product, especially in environments with high traffic or in places of higher risk.
Class A FRP Panels
-
As the highest fire rating for an FRP panel, Class A FRP panels are comparable to a standard that provides a higher likelihood of not being a potential hazard in the event of a fire.
-
The panels are tested for compliance with ASTM E84 or CAN/ULC S102 testing standards.
-
The flame spread index for Class A products is rated between 0-25, and with a limited amount of smoke, meaning that for areas with critical life safety concerns over roof and wall coverings, these are suitable.
-
Regulations require Class A materials in commercial kitchens, health care facilities, cleanrooms, retirement homes, medical facilities, and corridors close to fire areas, ideally in locations with many occupants.
-
Class A panels are also the most commonly selected because these panels limit flame spread and smoke development and can be relied on to provide a reasonable level of safety in all instances where safety and evacuation are a concern.
Class C FRP Panels
-
Class C FRP panels are most appropriate for general-use spaces, where the potential for fire is relatively low.
-
Class C materials have a flame spread index of 76-200 and are still considered safe for many installations and are code compliant.
-
Class C FRP is most often used in industrial buildings, utility rooms, warehouses, and some food processing facilities and commercial kitchens where high fire resistance is not required for code compliance or operational functions.
-
Class C panels offer the same benefits of FRP, such as moisture resistance, chemical resistance, and ease of cleaning, with a more standard level of fire safety.
Concluding Remarks
Ultimately, the determination between Class A and Class C depends on the project and the particular codes that apply to your location. In fire-sensitive environments, especially for projects dealing with occupancy, food preparation, or chemicals, using Class A panels provides an added level of safety. For general utility or light industrial use, Class C usually provides a cost-effective and compliant solution.
At Avanta, we offer both Class A and Class C FRP panels as well as adhesives, trims, and installation support so you can deliver each project with peace of mind, safety, and accuracy.
