When talking about building safety, especially in emergency situations such as fires, the selection of construction materials is not something that can be taken lightly. Behind the grand architectural design and functionality of a structure, there is one crucial element that is often overlooked, which is fire resistance. This is where Fiberglass Reinforced Plastic (FRP) begins to show its advantages.

Known as a modern material that is lightweight yet strong, FRP now also comes in a fire-resistant version, opening new opportunities for construction that is not only efficient but also safe. However, it is important to remember that not all FRP has the same ability to withstand heat and fire. So, what exactly needs to be understood about fire resistance in this material?

Understanding Flame Spread Rating (ASTM E84)

One important standard for measuring fire resistance in materials is ASTM E84, also known as the Surface Burning Characteristics of Building Materials. This test measures how quickly fire can spread on the surface of a material and how much smoke intensity is produced.

The test results are classified into three classes:

• Class A: Flame Spread Index 0–25 (lowest level of flame spread)

• Class B: Flame Spread Index 26–75

• Class C: Flame Spread Index 76–200

Materials that receive Class A are considered the safest and are recommended for high-risk buildings, such as public facilities, laboratories, and high-rise buildings.

Why Class A is Important for Industrial and Commercial Projects

When preparing material specifications for facilities such as malls, hospitals, or factories, the use of FRP with a Class A rating becomes important. Fire resistance is not only about asset protection, but also concerns the safety of people inside the building.

The use of Class A FRP helps reduce the rate of fire spread during a fire, provides more time for evacuation, and reduces the potential for major damage. In addition, FRP does not produce toxic gases when burned, making it superior to some other plastic or conventional materials.

Which FRP is the Safest for Public Areas?

Not all FRP has the same fire resistance performance. Therefore, it is very important to choose products that have passed tests and received certification according to national and international standards. FRP products labeled flame retardant and tested to ASTM E84 Class A are the most ideal choice.

Origa Mulia, as a specialist provider of FRP-based products, presents a variety of variants designed to meet the needs of projects with high safety standards. With experience in various industrial and commercial projects, Origa Mulia is able to provide FRP material solutions that are not only strong and corrosion-resistant, but also have proven fire resistance.

Choosing FRP for construction projects is not just about considering strength and lightweight properties. In the commercial and industrial sectors, fire resistance becomes a determining factor in maintaining long-term safety. Understanding classifications such as ASTM E84 and choosing FRP according to the required rating can help create buildings that are safe, efficient, and sustainable.
