Curtain boards are used to achieve which of the following?

Curtain boards are primarily used to control heat bank areas within a structure. They serve as barriers that help to manage the flow of heat, especially around areas prone to significant temperature variations, such as vertical spaces in a building. By strategically placing curtain boards, fire inspectors can ensure better compartmentalization of heat, which is crucial in preventing the spread of fire and smoke. This control is essential for maintaining the integrity of different thermal zones in a structure, mitigating the risks associated with heat accumulation and improving overall safety during a fire.

While curtain boards might have some indirect effects on insulation, room separation, and support for structural elements, their primary purpose lies in managing heat distribution and containment. Their design and application in fire safety protocols highlight their importance in maintaining safe environments and enhancing overall fire resistance in commercial and industrial spaces.
