Environmental protection is coming more and more into the limelight

Sto products contribute a great deal to our health and the environment and had already done so long before the term “environmental protection” found its way into the dictionary.


In fact, Sto had the idea of using polystyrene for thermal insulation as far back as 1964. Since then, 150 million tons less CO2 have been emitted thanks to Sto facade insulation systems.


In order to define and implement its ecological targets, Sto has developed a system of environmental management conforming to international standards. This relates to the entire process chain, from the procurement of the raw product, to production, packaging and logistics.
