Who are We?

APU AG, based in Schaffhausen (Switzerland), develops, produces and distributes high-quality plastic plaster connection profiles for interior and exterior plastering, as well as for external thermal insulation composite systems (ETICS).

APU - Quality assurance

In an elaborate testing procedure, our products are tested by independent testing institutes and subjected to the toughest conditions to demonstrate their suitability for practical use. This is documented by certificates and test reports for the individual products. Our priority is close and personal contact with our customers. Thus, through intensive and competent consultation and support, individual and high-quality plaster connections can be realized in addition to our standard solutions.

From our distribution center in Germany we supply our customers worldwide.

Our ambition is to offer more safety and to simplify the processing by continuous development and modification of the different connection profiles.

Our experience and adherence to the proven APU quality are essential factors in this. The basis of this quality is a company-wide quality management according to (DIN EN) ISO 9001.
