hollow core

Void inside structure

Hollow core describes construction materials—typically doors, concrete slabs, or panels—manufactured with internal voids rather than solid material throughout.

A hollow core door has a honeycomb or cardboard interior between thin outer veneers, making it lighter and cheaper than solid wood: The hollow core doors throughout the apartment did nothing to block sound.

Hollow core concrete uses cylindrical voids to reduce weight while maintaining structural integrity.
