Are Quad-Lock walls more resistant to rot and mold?
Yes. Quad-Lock walls themselves offer no medium for rot or mold to occur because they are solid, high-mass construction, with concrete filling the entire cavity of the forms. Concrete, steel, and EPS are all inert materials that do not rot nor sustain mildew. However, drywall contains paper which can support mold when combined with excessive moisture. So interior moisture should be controlled using spot removal (e.g. bathroom fans) and properly sized air conditioning units that will cycle long enough to dehumidify the air. Most wood-framed buildings are so susceptible to rot and mold because moisture can get trapped inside the open cavity of the walls despite a patchwork of house wraps, seals, caulk, tapes, and gaskets. The moisture combined with the organic materials allows mold and mildew to develop and rot to occur.
