Quality needs clear rules
Pioneering quality and reliable reliability are our top priority. That's why we get certified and checked regularly. In addition, we adhere to strict standards and ISO standards and have a management system for occupational safety.
Promote sustainable building
Which components are inserted in which installation situations? This has a decisive influence on the future viability of buildings. With Environmental Product Declarations (EPD), we present the environmental effects of our products in a transparent way: With precise information on energy and resource use throughout the entire life cycle – from production to disposal.
Sustainability certificates such as Emicode and other CE certificates also prove how environmentally friendly and sustainable our products are.
