What acclimation means
Flooring planks expand and contract with humidity and temperature. Boxes stored in a cold garage then installed in a heated room can gap or buckle as they adjust.
Acclimation means storing unopened cartons flat in the install room (or adjacent conditioned space) until they reach equilibrium with the home.
Typical timelines
Run HVAC at normal living conditions during acclimation and install. Read the carton — warranty may require specific humidity ranges.
- Laminate: often 48–72 hours; some brands say 24 hours minimum
- Solid hardwood: 3–7 days or longer; follow species and regional guidelines
- Luxury vinyl plank (LVP): 24–48 hours common
- Ceramic/porcelain tile: does not acclimate like wood — but store indoors to avoid thermal shock
