Product, system and project are three levels
The product level describes a material. The system level includes cooperating components. The project level adds the actual construction, detailing and execution.
A reliable claim always states at what level the evidence applies.
Common thinking errors
A CE marking is not a universal suitability mark. A BROOF classification does not automatically apply to every surface. A technical lifespan category is not an unconditional project guarantee.
A tested membrane can also fail with the wrong primer, insufficient preparation or too low consumption.
- No logo without a source
- No achievement without variation
- No classification without structure
- No guarantee without conditions
The value of a project passport
The project passport records which variant, substrate, primer, quantity and conditions were actually applied.
This creates a chain of control from technical document to implementation and maintenance.
This explanation is general and does not constitute project-specific system advice. Subsurface investigation, tax and official system documentation remain decisive.
