Concealed door hinges have a fascinating history, dating back to the early 20th century. However, they gained widespread popularity only in the 21st century when large-scale commercial manufacturing took off. Hidden door hinges have since become a staple in luxury real estate, particularly for trimless interior doors. As of 2024, concealed hinges are predominantly produced by five European manufacturers based in Italy and Germany.
The Evolution of Concealed Hinges
The journey of concealed hinges mirrors advancements in CNC-aided design and manufacturing. These innovations led to two key developments:
Flush Non-Rebated Doors: These doors feature straight edges, ensuring the door panel and casing form a seamless, single plane when closed.
Hidden Hinges: Traditional exposed butt hinges were replaced with concealed options, dramatically enhancing aesthetics and functionality.
Today, concealed hinges are available for various frame materials, including metal, aluminum, and wood. Specialized offset hinges even allow for wider throws, enabling the addition of cladding or extra panels to flush doors.
Key Specifications and Considerations
When selecting concealed hinges, weight capacity is a critical factor. For example, the AGB Eclipse 3.0 hinge supports doors up to 40 kg (88 lbs) with two hinges and up to 60 kg (132 lbs) with three hinges. To determine the number of hinges required, consider the following:
Door Dimensions: Height and width impact hinge load.
Door Weight: Heavier doors require more robust hinges.
Material Composition: Options include wood, MDF, glass, aluminum, and composites.
Frame Quality: Softwoods or knotty materials may weaken hinge grip.
