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.
In the midst of 19th century rapid industrial expansion a cement and lime factory is established in Weizen, Germany.
Wilhelm Stotmeister, owner of a lime plant in Klergen, expands his operation by acquiring the Weizen plant.
Stotmeister pioneers and introduces revolutionary high-quality synthetic resin wall coatings to the European market.
Founding of Stotmeister & Co. Farben-und Baustoff-KG: the Sto brand is born.
Sto introduces a new and innovative wall system: a cladding that creates an unbroken layer of insulation on the exterior of the building and integrates an acrylic-based resin coating that is extremely durable and long lasting. It is the first Exterior Insulation and Finish System.
Sto expands to the United States to market high-quality, energy-efficient Exterior Insulation and Finish Systems. Sto Energy Conservation, the first U.S. Sto company, is founded in Rutland, Vermont.
Sto helps form the EIMA, the EIFS Industry Members Association, in order to help establish industry-wide standards.
Sto Energy Conservation becomes Sto Industries, a company reflecting a wider market scope and an increasingly broader vision.
North American expansion continues. A branch office opens in California. Sto acquires PowerwallCorp., a Texas company later renamed Sto Concrete Restoration Division.
Sto Industries Canada Inc. is established on September 21, 1987 in Toronto.
National product sales reach unprecedented levels with help from the Sto Research Center. Sto moves headquarters to and builds a major manufacturing facility in Atlanta, Georgia, to efficiently handle the ever-increasing volume and to centralize operations.
Sto Canada becomes one of the founding members of the EIFS Council Canada to help establish industry-wide standards.
The rapid growth of product lines and plants necessitates the formation of Sto Corp., the unifying center of an international corporation.
Sto pioneers the air barrier business in Canada: Sto Flexyl, an acrylic-based, fiber-reinforced, flexible adhesive and waterproofing is tested as an air barrier material at Ortech in Mississauga, Ontario.
Sto opens a plant in Phoenix, Arizona, providing efficient services to the western United States.
Sto builds a 2-story building at CAN-BEST testing facility in Ontario to conduct the first research on EIFS performance with an air barrier. The evaluation results set a benchmark for all future testing of EIFS systems in Canada and help draft the first CCMC (Canadian Construction Materials Centre) Technical guide.
Sto Corp is the first EIFS manufacturer to conduct comprehensive testing to demonstrate water tight construction detailing in compliance with the BOCA (Building Officials Code Administrators International) code requirements. The large scale testing conducted at Intertek Testing Labs in Coquitlam, British Columbia included a test in hurricane weather conditions with dramatic winds generated by a DC 3 plane engine.
Sto Corp. obtains ISO 9001 certification.
Sto Corp. launches StoGuard®, the first liquid-applied air and moisture barrier for use over wood substrates.
Sto introduces Sto EmeraldCoat®, a spray-on air and moisture barrier designed for use under stucco and other non-adhesive claddings.
Sto launches StoCoat® Lotusan®, a revolutionary new coating with Lotus-Effect® Technology, the patented self-cleaning properties.
Sto renames the EIFS product line to StoTherm ci®, signifying the thermal and energy-efficient properties of EIFS cladding systems.
Sto Corp. achieves ISO 14001:2004 certification of the Environmental Management System for all North American facilities, reinforcing an ongoing commitment to the motto, “Building with Conscience.”
As Sto Canada celebrates its 25th anniversary, the company remains true to its long-standing tradition of innovation and technical excellence and becomes the first and only manufacturer to receive a CCMC evaluation for liquid-applied, water resistive barrier as a sheathing membrane behind all claddings incorporating mechanical attachments.
Sto Corp. expands internationally, acquiring locations in Chile and Brazil.
Sto celebrates its first North American direct sales depot with an event at the Toronto SalesCentre.
