FAQ
Questions and Answers
Is it laminate or engineered flooring?
SuperOak is unlike laminate and closer to engineered flooring — a real wood veneer over a waterproof core. It is made entirely with 3D-printing technology, meaning zero formaldehyde, zero emissions, greater underfoot comfort than solid wood, and over 30 non-repeating EIR patterns.
Is it PVC-free?
Our product contains no PVC or plastic components and is made from 100% recyclable materials. Defined as Hybrid Wood, it is fully sustainable — a responsible choice for environmentally conscious homeowners.
Is it really waterproof?
SuperOak offers superior waterproofing versus other laminate, engineered and solid wood floors. It has passed rigorous testing including NALFA certification, ensuring exceptional durability and moisture resistance.
