Invisible door hinges are also called hidden hinges and concealed hinges. It can’t be seen outside the door after installation, it is more beautiful and doesn’t affect the appearance of the door, mainly used in invisible doors and concealed doors.
Butt hinge is the most regular hinge, two stainless steel plates connected by a shaft, the function is to guarantee the opening and closing of the door, the butt hinge has a good load ability, mainly used in wooden doors, steel doors.
If you give a definition of the invisible hinge and flush hinge.
Invisible hinge: hidden between the door and the door frame, when the door is closed, the hinge is not visible in appearance.
Flush hinge: attached between the door and the door frame, when the door is closed, the shaft is exposed between the door and the door frame.
Concealed hinge and butt hinge, which is better? there is no exact answer, we have to choose the hinge according to the using conditions. For steel doors and fire-rated doors, we recommend using butt hinges, especially for high-frequency using doors. For interior wooden doors, both are suitable, we have to choose the right hinge according to the hinge characteristics.
Let’s understand the difference between flush hinges and invisible hinges from the 7 dimensions for interior doors.
1. Functionality
Generally speaking, flush hinges do not have the function of door adjustment, invisible hinges can adjust the up and down, frontward and backward, left and right. The adjustable function is to avoid the not standard installation and door deformation.
2. Aesthetics
The flush hinge shaft is exposed between the door and the door frame when the door is closed, and the gap between the door and the door frame is relatively large. The invisible hinge can not be seen when the door is closed. Generally, the gap between the door and the door frame is 2-3mm. using concealed hinges can achieve people’s aesthetic pursuit of a beautiful home environment needs.
3. Load-bearing
From the product structure movement principle aspect, flush hinges using single-axis fixed movement structure, load-bearing will be better, invisible hinges using multi-axis (normal is 7 axis) movable movement structure, load-bearing relatively low. However, the weight-bearing properties will directly affect the door’s sagging deformation, thus reducing the using life. When choosing door invisible hinges, the door weight and hinge load capacity be taken into consideration.
4. Anti-theft
When the door is closed, the shaft of the butt hinge is leaking out of the door, which will lead to poor security if the shaft is damaged. But the invisible hinge is completely hidden, and relatively better security.
5. Security risks
When the door is closed, there is an object stuck in the closing process, the degree of injury is less because of the structure of the flush hinge movement principle. However, invisible hinges will be a greater degree of injury, when objects are stuck in the door-closing process.
6. The material requirements of the door
In the case of the same torque, generally speaking, flush hinges on the door material requirements are relatively low, while invisible hinges on the door material requirements are relatively high. On the other hand, the invisible hinge requires deep processing of the door and door frame.
7. After-sales hidden trouble
The size specifications of the butt hinge are conventional and easy to purchase when there is an after-sales replacement, while the current market invisible hinge specifications are diverse, with different sizes, different materials, and finishes.
The advantages and applications of hidden hinges
Hidden door hinges can be applied to interior doors, invisible doors, folding doors, etc. They are suitable for hotels, offices, clubs, villas, and other project types, with the design concept to achieve complete concealment when the door is closed, no trace can be seen, and silent opening and closing.
There are 5 major advantages compared with butt hinge, which are as follows
No distinction between left and right door: installation without distinction between left and right door, it’s a more convenient installation.
Invisible design: hidden installation, simple, beautiful, and generous.
Three-dimensional adjustable: adjustable in three directions, no need to disassemble the door to achieve adjustment.
Sound-deadening design: sound-deadening nylon cushion, multi-link connection, silent and wear-resistant.
Adjustment after door sagging: load-bearing is better than ordinary hinges, and can reduce the door sagging hidden trouble; the door deformation sagging after use a long time can also be properly adjusted.
