A slab door can be classified as which of the following?

A slab door can indeed be classified as solid or hollow core. The distinction between solid and hollow core refers to the internal structure of the door. Solid core doors are made from solid materials, which provide greater durability, sound insulation, and impact resistance. They are typically heavier and more secure than their counterparts.

On the other hand, hollow core doors are lighter and often constructed with an internal framework that creates voids or spaces within the door, filled with materials such as cardboard or honeycomb structures. This makes them easier to handle and less expensive to manufacture, but they usually offer lower isolation and security compared to solid core doors.

Understanding these classifications is important in the context of fire safety, as different door constructions can impact fire-resistance ratings and the overall effectiveness in containing smoke and fire.

The other classifications, such as panel or flush, metal or wood, and single or double, refer to different characteristics of doors but do not specifically address the core structure in the same way that solid or hollow core does. Panel or flush describes the visible design, metal or wood refers to material type, and single or double indicates the arrangement or number of door leafs, but none of these options consider the structural core of the slab door, which is
