Before installation, flooring must reach equilibrium with the room's environment. This involves storing materials in the installation space for a duration specified by the manufacturer—typically 48 to 72 hours. During this time, the HVAC system should be operating normally. Humidity and temperature must be within the specified ranges, as wood and even some resilient products react to moisture. If the material is not properly acclimated, it may shrink or expand after installation, causing gaps or pressure-induced buckling that the manufacturer will not cover under warranty.
