Fire features and fire pits are increasingly popular in outdoor living environments. Fire can damage many building products, including Fiberon decking. Improperly installed fire features and fire pits can cause damage to the surface of Fiberon decking via direct exposure to the flame or excessive radiated heat. Proper caution should be taken when designing, installing and using these features to ensure damage does not result.
