Claim C-0007
Newly installed laminate flooring and wood-based panels may be associated with raised indoor formaldehyde.
Structure
- Source
- Laminate flooring, Wood-based panels (particleboard, MDF, plywood)
- Factor
- Formaldehyde (CH₂O)
- Relation
- increases · 0.038 ppm measured in a test room after installation; up to 0.093 mg/m³ modelled for 20 m² of medium density fibreboard at 0.5 air changes per hour
- Evidence grade
- C · consistent
- Caveat
- measurement campaigns and a chamber model, not epidemiology; concentrations fall as the material ages and with ventilation; F-0015 is an estimated steady-state concentration from a model, not a measurement in a home; only F-0013 is measured, and its authors are a consultancy
Based on
- Finding F-0013: “Mean formaldehyde concentrations following installation were 0.038 and 0.022 ppm for Products 1 and 2 respectively, and 7 days after flooring removal the concentrations returned to background preinstallation levels.” (CKB 0257, p. 1)
- Finding F-0015: “For the typical residential ventilation scenario (0.5 h−1 ), concentrations decreased proportionally, reaching maximum values of 0.093 mg m−3 for MDF and 0.090 mg m−3 for melamine (20 m2 ).” (CKB 1036, p. 8)
