As a company that serves both living and industry, PS has been working since its establishment in 1960 on the theme of "climate" indoors, focusing on humidity and radiant heating and cooling, to create spaces where people can comfortably engage in activities. The indoor climate of PS is about creating an environment where people can live healthily and comfortably, just as there is a natural climate outside. PS positions indoor climate as a second nature and continues to propose robust spaces that are energy-efficient, comfortable, and durable, starting with homes and extending to various environments that support people's lives.
