Utah’s low winter humidity — often 10–30% indoors without humidification — creates real challenges for wood flooring. Engineered hardwood and luxury vinyl plank (LVP) handle Utah’s humidity fluctuations far better than solid hardwood because their multi-layer construction resists expansion and contraction. Solid hardwood can work in Utah, but it requires careful acclimation, verified subfloor moisture levels, and a whole-home humidification system that maintains 35–50% RH to prevent seasonal gapping. RainFire Builders performs moisture testing before every wood installation — no exceptions.
