VERT / GREEN
New installation without leakage signs: inspect flashing, drainage and joints before enclosure.
Controlled building-envelope water penetration testing
Test windows, doors or envelope interfaces using a controlled method that represents relevant exposure without intentionally flooding the assembly.
JAUNE / YELLOW
High-exposure project or recurring defect: consider standardized field testing early enough to correct details.
ROUGE / RED
An improvised hose test can unrealistically overload details, redirect water or cause damage; use a defined method.
Construction triage
What the professional checks
- Select suitable standard/protocol for window or assembly
- Interpret water path and confirm correction by retest
