The reason behind the hardwood cupping is mainly the moisture content because moisture built up in the hardwood floors results into the expanding and wrapping of the wood flooring. The temperature controlled rooms do not get much affected with cupping, however, if the water stays for a more longer time on the floor it may cause the floor to cup if not treated immediately with dehumidifiers.
