Fire Resistance Ratings of WPC Board Material: What Homeowners Need to Know

We make WPC boards every day, and the question we hear most from homeowners is, Will this stuff burn? The short answer is no—at least not easily—if you choose the right grade. Below, we explain fire ratings in everyday words and show how the same boards can also be upgraded with acoustic sound absorbers, acoustic wall sheeting, and decorative aesthetic panels without lowering safety.

Why WPC chars instead of drips

Wood-plastic composite is a mix of wood fiber and plastic. When fire touches it, the outer skin swells into a dark, hard char. This char blocks heat from moving deeper, so the board keeps its shape longer than ordinary wood. That matters when you plan to add acoustic wall sheeting on top. A stable base means the extra layers stay in place during a fire, giving firefighters more time.

Adding safety without losing style

Some homeowners worry that thicker fire-safe boards will look dull. We solve this by offering matching aesthetic panels that click onto the same hidden clips. You get the fire rating in the core and the look you want on the face. Want a warm teak stripe or a cool cement gray? Both are available as aesthetic panels with the same fire class as the base board.

Sound and fire together

Noise control is the next request we hear. Our standard boards already cut some echo, but you can boost the effect with factory-made acoustic sound absorbers. These are thin pads that bond to the back of the board before it leaves our plant. The pads are made from recycled cotton treated with a fire-blocking salt, so they meet the same rating as the board itself. In field tests, a living room lined with these boards plus acoustic sound absorbers dropped TV bounce by half.

Retrofit options

Already built a deck and now want a quieter patio wall? We sell acoustic wall sheeting that screws right over the old boards. The sheeting is grooved like our deck planks, so it still counts as aesthetic panels from the street side. The hidden layer is made from the same fire-rated core stock, so your wall now meets code and muffles neighborhood noise at the same time.

Kitchens and bathrooms

Steam and grease worry some buyers, but our fire-rated boards shrug off both. We add a thin cap layer that also works as acoustic wall sheeting, keeping cooking clatter inside the room. Home chefs like the matte finish of these aesthetic panels because spills wipe off with soap and water.

Balconies and high-rises

High-rise rules are tougher. We supply boards with a core that reaches Euro Class B-s1,d0 and still accepts snap-on aesthetic panels for each balcony face. The boards act like vertical acoustic sound absorbers, softening street noise before it enters the apartment. Installers simply treat the balcony ceiling as acoustic wall sheeting and use the same clip system, saving labor hours.

At EverGreen WPC Works, we believe safety and comfort should arrive in the same truck. With the right mix of fire-safe core, acoustic sound absorbers, smart acoustic wall sheeting, and beautiful aesthetic panels, your home stays quiet, stylish, and protected.
