According to recent tests, how long does it typically take for lightweight engineered lumber to collapse?

The typical time it takes for lightweight engineered lumber to collapse is based on fire exposure and the inherent properties of the materials used in lightweight construction. Recent tests and research indicate that this type of lumber can reach a critical failure point at around 6 minutes when subjected to fire conditions. This is due to the high surface-to-mass ratio of engineered wood products, which allows them to ignite and weaken more quickly than traditional lumber.

Understanding this timeframe is crucial for firefighters in suburban environments, as it impacts tactical decision-making during structure fires. Being aware of the quick collapse potential of lightweight engineered structures can help fire crews assess risks and implement strategies to protect themselves and effectively combat fires, especially in residential areas where such materials are frequently used in construction.
