Certifications & testing
Tested. Approved. Documented.
iverclack is a patented Italian system, and its reliability is evidenced not by marketing but by the protocols of independent European bodies. Below are the bodies that issued the approvals, the standards the materials and joints meet, and the methods the system has been tested against.
As the authorised dealer, Terra-Zenith supplies the manufacturer's current test protocols and technical documentation scoped to a specific project. We deliberately do not publish certificate numbers we cannot back with a document — that is precisely what separates us from the forgeries in this market.
Tested. Approved. Documented — by the same European bodies on which water-tightness in 35 countries rests.
Approval bodies
The system and its components are assessed by independent European building-technology institutes and insurance laboratories.
German Institute for Building Technology — national technical approval (abZ) for metal roofing systems.
British Board of Agrément — fitness-for-purpose assessment of the roofing system for UK construction.
Centre Scientifique et Technique du Bâtiment — technical assessment (Avis Technique) for the French market.
Independent inspection and testing of materials and the seam connection.
Insurance-grade certification of the roof blanket for wind uplift and fire performance (FM 4471).

Engineering methodology (not a certificate)
For Russian projects, snow and wind load calculations are performed to SP 20.13330 and aligned with the structural design — this is the dealer's engineering practice, not a separate product certificate. European calculations follow EN 1991 (Eurocode 1).
Russian-market documentation (protocols, assessments, calculation justifications) is prepared for the specific building at the "P" and "RD" stages. Request the set for your project — we assemble it from the manufacturer's current documents and the project calculations.
