Natural flooring materials are hygroscopic, meaning they absorb and release moisture based on the ambient environment. Before installation, flooring materials must be acclimated to the site's temperature and humidity levels to minimize post-installation movement. If the relative humidity deviates significantly from the manufacturer's recommendations, the material may expand beyond the provided expansion gaps, causing the floor to heave. Proper climate control is required during and after the installation.

What is the impact of site humidity on flooring material expansion?
Site humidity directly impacts wood and laminate flooring by causing material expansion or contraction. Excessive humidity can lead to cupping, buckling, or warping, while overly dry conditions may cause gaps to form between planks, compromising the aesthetic and structural integrity.
