What is the necessary expansion space when installing the hardwood flooring?
Wood is the primary component of moderna® Solid & Engineered Hardwood Flooring. Since almost all wood products react to varying degrees in humidity, this flooring product must be allowed to expand in all directions. This expansion can be up to 3/32″ (2.4mm) per yard (914mm). To facilitate this, an expansion gap of 1/2″ (12.7mm) must be provided at all sides of the floor. A gap must also be provided around pipes or at thresholds. The greater the surface area covered, the greater the required space for expansion. The floor must be able to expand or contract in ALL directions. A space of 5/16″ – 13/32″ or 1/4″ for every 10’ (8mm-10.5mm or 6.5mm for every 3050mm), must be allowed for at all walls, at thresholds or when installing flooring around pipes. Use doorways as additional expansion gaps. These gaps will be covered with molding attached to the base floor upon completion of the installation. Remember, for installation in large rooms, transition moldings must be used for every 33’ (10m
