The foundations of modern textile facade systems and their advanced passive cooling properties were laid long before they became a staple of sustainable architecture. The story of roho professional is one of continuous revolution—from chemistry to large-scale industrial engineering.

It began with Roland Hoffmann, a chemist and founder of Roho, who established a specialized laboratory to develop the groundbreaking Diadirekt photo process. This innovation was a true industry disruptor, delivering significantly higher quality while simultaneously reducing costs. It quickly became the gold standard in the professional photo industry, giving birth to the brand name roho professional.

Today, this rich legacy has been carried forward by an internationally active, publicly traded corporation (AG). This transition has empowered us to expand our reach and integrate synergistic product lines that perfectly complement our core facade technology. We now operate on a global scale, serving high-profile industrial clients and delivering large-format solutions for critical infrastructure projects.

At the same time, CH PRO actively supports open-source initiatives and allocates a portion of its proceeds to both open-source and social projects. We are committed to advancing sustainable innovation and have developed proprietary technologies in areas such as food production. One example is a system where greenhouses are passively cooled and nitrates are generated from ambient air and delivered to plants via aeroponics—an energy-efficient alternative to conventional fertilizer production.

In addition, we are at the forefront of digitalization and operate the real estate platform Salesign, further expanding our technological ecosystem.
