Final answer:
Control joints are recommended in large ceiling areas to relieve internal stress buildup.
Step-by-step explanation:
In large ceiling areas, control joints are recommended to relieve internal stress buildup. These joints are used in construction to prevent cracks caused by thermal expansion and contraction of materials. Control joints are typically placed in regular intervals and are designed to allow for movement while maintaining the integrity of the structure. They are often seen in large concrete slabs, such as ceilings, floors, and walls, as well as in other structural elements.
