When wildfire is a concern, the decking material matters. LumberCon's prestressed concrete planks are noncombustible, a step beyond the “fire-resistant” label on many wood and composite boards. If you've been searching for fireproof decking, noncombustible is the tested standard to look for.

Proven Fire Performance

  • ASTM E136: Classified as noncombustible, meaning the planks did not ignite or burn under the test's conditions.
  • ASTM E84: Class A, with a Flame Spread Index of 0.

How LumberCon Compares

  • LumberCon: prestressed concrete planks that are noncombustible and won't rot or attract insects.
  • Competitors: Wood, composites, and plastic decking may be labeled “fire-resistant,” but they can still ignite, melt, or spread flames under extreme heat.

Wildfire Zones (WUI)

California's Wildland-Urban Interface (WUI) rules set fire standards for decking in wildfire-prone areas. LumberCon's noncombustible and Class A results are relevant to those rules. Our California State Fire Marshal listing is in progress. Check with your local building department for your project's requirements.

Insurance

Some insurers look at building materials when writing coverage in wildfire-risk areas. Ask your insurer whether noncombustible decking makes a difference for your property.
