DAkkS (Deutsche Akkreditierungsstelle) is Germany’s national accreditation body, ensuring laboratories operate with verified technical competence and international credibility. PIV, as a DAkkS-accredited institute (EN ISO/IEC 17025), provides independent and reproducible test results recognised worldwide. For architects and consultants, this ensures that performance values are objective, traceable, and suitable for EN-based project specifications.

The verified performance results highlight CIVRO systems’ ability to deliver: High Airtightness: Optimised for energy efficiency and thermal comfort Reliable Water Resistance: Proven under extreme rain conditions Structural Stability: Tested to withstand high wind loads These results provide confidence for specifying CIVRO products in residential, commercial, and high-rise applications, backed by a European compliance framework rather than internal testing alone. “Certification from a DAkkS-accredited PIV institute confirms that our engineering meets the highest international standards. Architects and developers can specify CIVRO systems knowing they deliver consistent performance under real-world conditions,” said CIVRO CEO Mr. Ken Tam.
