Which cut is ideal for roofs with extensive metal decking?

The triangular cut is particularly effective for roofs with extensive metal decking. This cut allows for effective ventilation, as the triangular shape creates a larger opening and facilitates the escape of heat and smoke from the interior of a structure. The angle of the cut also helps in directing airflow, which is critical during firefighting operations, as it maximizes the amount of hot gases that can be expelled while still maintaining the structural integrity of the surrounding roof.

In contrast, other cuts may not provide the same level of efficiency or may compromise the stability of the roof. For instance, the square cut can create a larger hole but may lead to difficulties in controlling the flow of heat and smoke. The louver cut can be beneficial for ventilation but may not be the best for roofs that have significant metal decking, as it requires precise angles and can be more challenging to execute effectively. The peak cut, while useful in some situations, may not be as optimal as the triangular cut when dealing with metal roofing, which can complicate the operation due to its rigidity and the potential for creating hazardous slide-off debris.
