The SonoWall line of stucco and "stucco-look" wall systems was first introduced in 1994 by a team of experienced construction professionals, utilizing the waterproofing and coatings expertise of Sonneborn’s R & D department. The SonoWall brand grew quickly. The reliability of its product quality, coupled with its dedicated, enthusiastic and knowledgeable team have proven to be a combination that architects, builders and contractors value highly. Since January 2001, SonoWall has been part of the BASF Construction Chemicals Division. BASF, the world’s largest chemicals company, employs over 81,000 worldwide.
