Preserving & Growing Market Share

  • By conducting its own ASTM E119 floor assembly fire testing, SBCA has the data it needs to effectively fight the controversial IRC Section R501.3 code provision and help preserve CMs’ market share.
  • SBCA has drafted template best practice language CMs should consider using in their TDDs, customer contracts and submittal documents to counter the efforts of the lumber industry to shift liability onto end users.
  • Through Framing the American Dream and WorkForce Development efforts, SBCA is actively engaged in helping CMs successfully navigate today’s labor challenges and grow their businesses.
