When we bring any material into our homes or workplaces, especially in large quantities, it’s natural to wonder about its fire safety.

Nobody wants to install something that could potentially be a fire hazard. So, how do fiberglass acoustic panels measure up in this regard?

Generally, fiberglass is considered to be a fire-resistant material. This means that it won’t easily catch fire and is designed to slow down the spread of flames.

However, it’s crucial to differentiate between being fire “resistant” and fire “proof.”

Fire-resistant means that the material will retard the spread of fire, but it doesn’t mean it’s entirely immune to it.

Look For Class A Fire Rating

When looking to purchase fiberglass acoustic panels, always check for fire safety certifications.

These are usually provided by the manufacturer and indicate that the product meets established fire safety standards.

Most panels that are up to code will have a Class A fire rating, which is the highest standard of fire resistance for building materials.

However, fire resistance is not a permanent attribute. Over time, as panels are exposed to various environmental factors, their fire-resistant qualities can degrade.

This makes regular inspection a necessary part of long-term maintenance. Checking your panels for signs of wear and tear not only ensures their effectiveness but also their safety.
