Wilmington, Ohio —As the population in the U.S. continues to expand, so does the need for developable land. This is creating areas where structures now meet with undeveloped wildlands and the difficulty associated with properly containing wild fires can make for dangerous situations.
Several states have revised their building codes to ensure exterior products will help mitigate potential damage caused by fires. So far, California has enacted the most comprehensive set of regulations and these were put in place in 2008.
According to the California Department of Forestry and Fire Protection, “The broad objective of the Wildland-Urban Interface Fire (WUI) Area Building Standards is to establish minimum standards for materials and material assemblies and provide a reasonable level of exterior wildfire exposure protection for buildings in Wildland-Urban Interface Fire Areas.”
TimberTech offers four deck boards that meet this standard; DockSider, EarthWood, TwinFinish and XLM. DockSider, Earthwood and TwinFinish are composite planks and meet the Class B designation for Flame Spread. XLM, TimberTech’s all PVC extreme low-maintenance plank, passed the ASTM-E84 requirements to achieve a Class A Flame Spread Rating, one of the most stringent ratings available for fire resistance.
Products must undergo rigorous testing to be approved for use in Wildland-Urban Interface regions. Only those deck boards that pass SFM Standard 12-7A-4 testing requirements are published in the Wildland-Urban Interface Handbook as approved for use by the Office of the State Fire Marshal.
