The History of Sto

Sto's headquarters in Germany symbolizes the company's dedication to innovation, energy efficiency and the building technologies of tomorrow.

Sto's headquarters in Germany symbolizes the company's dedication to innovation, energy efficiency and the building technologies of tomorrow.

The global giant now called Sto evolved from humble beginnings as a cement and lime factory in Weizen, Germany in the 1830s. More than a century later, entrepreneur William Stotmeister expanded on this operation by introducing a range of revolutionary resin wall coatings, and Sto ultimately evolved into an international technology leader in the design and production of innovative external wall insulation systems, rainscreen cladding, decorative coatings and acoustic systems for regulating room noise.

Now operating as STO SE & Co KGaA, in Stuhlingen, Germany, the parent company launched operations in the U.S in 1979, establishing Sto Energy Conservation in Vermont. In 1986, North American expansion continued in California and Texas and eventually into Canada. In 1987, in order to centralize operations and accommodate unprecedented sales volume, Sto Corp. North American headquarters were moved to Atlanta — also the site of a major new manufacturing facility. In 2014, the company launched operations in Brazil and Chile.

Today, Sto Group is the world’s largest manufacturer of exterior thermal insulation systems, encompassing 35 subsidiaries, more than 5000 employees, and 21 factories operating around the globe. The company has consistently been on the technological leading edge, investing heavily in scientific research and product development.

This has resulted in a stream of innovations, including the introduction of the first exterior wall cladding system offering continuous insulation in 1963, and product breakthroughs such as the first liquid-applied air moisture barrier (2000) and Sto’s patented StoCoat® Lotusan® coating with self-cleaning properties (2005).

The company focuses on supporting the needs of the architecture and design community with educational services such as its London-based Werkstatt exhibition space, AIA/CES professional courses and the aesthetic consulting services provided by Sto Studio in the U.S.

For over 60 years, Sto — still controlled by the Stotmeister family — has continuing to develop innovative, next-generation building and design solutions based on superior product performance, professional expertise and success in building strong relationships through knowledgeable, customized service. Sto wall systems, coatings and finishes continue to be the choice of leading architects, designers, engineers, contractors and building owners around the world.


Sto Corp. Combines Form and Function at the 2015 AIA Expo

In May, the Georgia World Congress Center in Atlanta, GA hosted thousands of architects and over 800 construction industry exhibitors for the 2015 AIA Expo. The Georgia World Congress Center boasts over 170,000 square feet of exhibition space and it needed every last bit of it for the AIA Expo, one of the largest gatherings of architects and design professionals in the world. Sto Corp., whose headquarters is based in Atlanta, GA was one of the many exhibitors who participated in this year’s AIA Expo, and they pulled out all the stops. “This year AIA was in our hometown so we wanted to do something bold, new and clearly distinct from previous years,” said Valerie Mayer, Sto Corp.’s Manager of Marketing Communications. To reinforce Sto Corp’s connection to the larger Sto global family, this year’s AIA booth included a gallery of high profile projects from around the world featuring a variety of Sto’s different wall systems and building envelope solutions.    Among the various systems and solutions that Sto had to display were samples of Sto’s Ventec rainscreen cladding systems. The Ventec systems offer the highest degree of performance in terms of long term sustainability and durability. Largely a green system, Sto’s unique StoVentec carrier board is made from 96% recycled glass. StoVentec systems feature a myriad of aesthetic and design options including glass mosaic, natural stone, and even photovoltaic façades. Throughout the booth, Sto’s four core values; innovation, relationship, performance, and sustainability; were represented. Amongst the innovations being presented were StoPanel Technologies pre-fabricated façade systems. “Unlike other panelized facades, StoPanel Technology is the only system that uses standardized materials, details, and design considerations. We have built a network of contractors and engineers across the Americas who are sharing best practices and constructing the same superior panelized wall systems regardless of design or location,” said Dominick Baruffi, executive director of StoPanel Technology. All Sto wall systems begin with Sto’s industry leading air and moisture barrier system, StoGuard. This year’s booth included a number of videos showing that air tightness and moisture resistance with StoGuard is not only durable enough to last the lifetime of a building, but can be installed much more simply than more conventional systems.    Of course excellent building performance means little if the building is an eyesore, which is why Sto chose to show off its more creative side as well. “Form and function should go hand in hand. Architecture really is functional art,” said Billy Rosbottom, manager of Sto Studio. An inspiration wall on the outside of the Sto’s booth showed off a variety of different aesthetic options that could easily be achieved using Sto’s various different finishes, as well as natural elements that helped […]
