UFFI and renovation of an older home

Identify legacy urea-formaldehyde foam insulation before opening walls, energy retrofits or major property work.

VERT / GREEN

Document construction/renovation era and visible clues without unnecessarily opening cavities.

JAUNE / YELLOW

UFFI is a legacy material prohibited in Canada since 1980; its presence can change renovation planning.

ROUGE / RED

Unknown material, indoor-air concerns, cavities to open or removal contemplated: professional assessment before work.

Interactive triage

This triage helps choose the next step; it does not replace design, permitting or professional diagnosis.
