Company History

Sto is recognized worldwide as a leader in integrated exterior wall systems, but we had humble beginnings as a single plant in 1830s Germany. From there, we have continuously grown across countries, continents and industries. Today, we have plants and offices spanning the globe, all of which work toward the goal of making smarter buildings by uncovering new technologies, developing advanced new systems and improving existing products.
