Fire doors can be made with a combination of timber, steel, gypsum, and aluminum, and the most widdely used ones are Steel Fire Door and Wood Fire Door. They can also have windows, which are made from borosilicate or ceramic glass (both of which offer a higher fire resistance than standard glass), and may contain an anti-shattering wire mesh.

To enhance their fire-stopping abilities, fire doors are flush with the frame. Any or all gaps are filled with silicone-based fire-resistant sealant. These are often accompanied by a keluar (exit) sign and an intumescent strip attached at the bottom of the door, which expands when exposed to heat to prevent smoke from seeping underneath.

Fire doors are commonly designed to include a closing mechanism. Usually fitted at the top of a door, these spring-loaded or hydraulic mechanisms force the door closed, preventing fire and smoke from passing from one area to another.

Just like fire doors, many Security Doors and Hospital Doors are also uses Wooden Doors or even Steel Doors to ensure better security.
