Spray polyurethane foam: assembly and quality control

Verify product, installer, substrate, thickness, adhesion, vapour/air strategy and fire protection before enclosure.

Important: this tool helps decide what to verify; it does not replace calculations, permits or professional design where required.

VERT / GREEN

Document product label, installer, batch and applied areas.

JAUNE / YELLOW

Foam can change roof/wall drying and make defects or leaks harder to see.

ROUGE / RED

Persistent odour, friable/shrunken foam, wet substrate, unknown product or missing required thermal barrier: obtain professional evaluation before enclosure/occupancy.

Indicative triage

No product/QA record
Recover product identification and system requirements. Wet substrate or active leak
Correct the water source before spraying. Discoloured/friable/shrunken foam
Have adhesion and installation assessed. Installer/QA program documented
Keep records with the home file.
