Understanding Mold: Biology, Risks, and Building Implications

Before diving into prevention strategies, it is vital to know the nature of mold as a organic entity, its most popular growth conditions, and the broader consequences for buildings and inhabitants. Mold is a kind of fungus that thrives in damp, heat, and oxygen-rich environments. Its spores are microscopic and airborne, making them simple to disperse throughout indoor areas as soon as mould is established.

Mold Growth Requirements and Lifecycle

Mold requires 4 essential conditions to develop: moisture, organic material (food), warmth, and time. Moisture typically results from leaks, condensation, or high humidity. Organic supplies similar to wood, paper, drywall, and fabric present vitamins. Most molds thrive in temperatures between 77°F and 86°F (25°C to 30°C), though some species can survive exterior this range. Understanding these situations underscores why moisture control is the primary prevention strategy.

Health and Safety Risks of Mold
