A BRIEF HISTORY OF ACCESS DOORS AND PANELS 

Early Beginnings: Access doors trace back to ancient civilizations, where primitive openings covered with removable materials like stones or wooden panels allowed access to hidden chambers, passages, and flat rooftops.

Industrial Revolution and Advancements: The Industrial Revolution brought manufacturing techniques and materials advancements. Basic hinged doors and panels began to emerge, offering improved functionality and durability in industrial settings. For example, sack traps facilitated the bagging process in old mills, and ships featured hatches and holds.

20th Century Innovations: Along with trapdoors in the gallows, the 20th century witnessed the demand for access doors seamlessly integrated with building design. Manufacturers started producing access doors with cleaner lines and concealed hinges, enhancing their visual appeal in modern architecture. 

Specialized Applications: With the growth of complex buildings, fire-rated and acoustic access doors addressed specific needs. Fire-rated doors ensured safety compliance, while acoustic doors catered to noise-sensitive spaces like theaters and studios. 

Integration and Innovation: The rise of drywall construction introduced drywall inlay access doors, seamlessly blending with drywall surfaces. This innovation offered hidden entry points without disrupting the visual continuity of space. 

Modern Solutions: In recent decades, access door models with advanced features like touch latches and keyless entry emerged, aligning with contemporary design and technology trends.
