Ask what is certified
Clarify whether a claim relates to a product, installation process, supplier or a specific property such as security. Request the relevant documentation and verify it with the issuing organisation where appropriate.
Compare the complete assembly
Frame, glass, hardware, fixings and installation details work together. A certified component does not automatically establish the performance of a different assembled system.
Match the evidence to your needs
Identify requirements for the actual opening and use before choosing products. Keep the agreed specification alongside any supporting certificates or test information.
No assumed company credentials
This page explains how to assess evidence and does not claim unverified certification for Multi Concurrent. Ask for written product information and installation responsibilities as part of the quote.
