What is a curtain board used for in a fire situation?

A curtain board is used in a fire situation to divide the roof into compartments, which helps in confining the fire to a specific area. This compartmentalization allows for better control of the fire, as it limits its spread and helps to maintain a more manageable environment for firefighting efforts. By utilizing curtain boards, firefighters can create barriers that slow down the movement of smoke and heat, protecting other areas from being affected and improving the overall safety of the incident scene.

The design and implementation of curtain boards are particularly useful in large structures where the potential for fire spread is greater. By compartmentalizing spaces, it also contributes to protecting valuable property and supporting evacuation efforts. This tactic can effectively assist in preserving structural integrity and buying additional time for rescue and suppression efforts.
