For homeowner customers who live in a fire zone, choosing a deck can鈥檛 just be about selecting a favorite style and color. They also need to choose fire-resistant decking that can help protect their home and family in the event of a wildfire.
It鈥檚 important to understand that no wood or composite decking is truly fireproof. However, there are fire-rated decking options with specific certifications that make them a better choice for homes in fire zones.
UNDERSTANDING RATINGS AND REQUIREMENTS听
One way to choose is by looking at a听material鈥檚 flame spread rating. A flame spread rating听measures how fast and far a flame spreads over a certain material. Testing for flame spread rating听involves burning materials under controlled conditions and measuring the speed and extent of flame spread. The resulting number is the flame spread index, which ranges from 0-200.
The best flame spread rating is Class A (with an index of 0-25). Lower classes, Class B (26-75) and Class C (76-200), indicate that flames spread more quickly and covered a greater distance over the material than Class A flame spread-rated materials.
Ratings for flame spread are incorporated into the model building codes as published by the International Code Council, including the International Building Code (IBC), the International Residential Code (IRC), and the International Fire Code (IFC), to name a few.
Along with flame spread rating, you may have heard of WUI-compliance. , which听stands for 鈥淲ildlife Urban Interface,鈥 designates areas that are within or adjacent to communities deemed 鈥渁t-risk鈥 for wildfires.听 refer to those below a certain threshold for flame spread.
Some jurisdictions designated as Wildlife Urban Interface areas, especially in California, Colorado, and Nevada, require that certain building products meet the Class A Flame Spread Index rating.
However, it鈥檚 important to note that just because a product is WUI-compliant, does not mean it has a Class A Flame Spread Index rating 鈥 and vice versa. In order for a material to meet the standards for a Class A Flame Spread Rating and WUI compliance, it would need to undergo specific testing for each classification.
ARE COMPOSITE AND PVC DECKING FIRE-RESISTANT?
In comparison to wood, composite decking is often a better choice for fire-prone areas. Composite decking is made of a mixture of wood and plastic fibers, making it less susceptible to flame spread than many types of wood. But not all composite decking is created equal. Some types of composite decking have been , while others have not, meaning there鈥檚 a wide range of fire ratings among composite products.
PVC decking is made from 100% polymer (PVC) material and typically no wood fibers, making it a good fire-resistant decking choice for fire-prone areas. But just like composite, not all types of PVC decking are created equal. It requires specific, advanced engineering to create PVC decking that reduces flame spread enough to earn a . 听
