What are Concealed Hinges
Updated: Oct 28, 2020
How can you have a door where the hinges are not seen? Rather than seeing the butt of a hinge, I just want to see the door in its frame and no metal protrusion.
A concealed hinge is one that lays flush within the door to mask the hinges location. The purpose of the concealed hinge (aka invisible hinge) is to provide a smooth surface to the outer perimeter of the door.
The major advantage, beyond the purely aesthetic value of concealed hinges, is the ability to make minor adjustments very simply to the seating of the doors after they are installed, by turning small adjustment screws.
The Standard Door
There is no need for unsightly butt hinges or pivot kits, the concealed hinge brings a clean aesthetic appeal to a door, allowing it to blend into the wall.
The invisible hinge has been designed to allow a door to open and close, as would any other hinge, but with one difference; you don’t see it.
Most concealed door hinges are rated to carry between 60 - 160 kg door to 90° or 180° opening depending on the model. The hinge is extremely versatile and reliable as it is rated to 100,000 opening and closing cycles. Once installed the hinge becomes totally invisible when the door is closed, providing a clean, sophisticated blended door to wall look.
Unlike traditional hinges where the two leaves of the hinge meet and protrude out past the jamb and face of the door, the invisible hinge is hidden away by the door jamb and the door which butts up against each other when the door is closed, with only a minimum 2 mm gap.
An added advantage of the invisible hinge is its appearance; aesthetically pleasing to the eye when the door is open, it is sleek and has clean lines.
Cost effective and highly functional, it is a real and effective alternative to traditional and unsightly butt hinges and pivot systems. It’s guaranteed for 100,000 cycles. The invisible hinge is hard to overlook even when you can not see it.
For Glass Doors
Specifically designed to butt glass doors up against a wall or jamb, the invisible hinge adjustable concealed patch plate hinge is rated to hold a 8-10mm thick 60kg glass door to 90° or 180° opening. It’s revolutionary in it’s design by combining a patch plate and invisible hinge together.
Not only can you adjust the position of the glass door in 2 dimensions (up down & left, right) but you can also take the door down without having to remove the hinge from its rebated housing in the jamb or wall.
The hinge has been tested to 150,000 opening and closing cycles. Cost effective and highly functional, it is a real and effective alternative to traditional and unsightly glass door hinges and pivot systems.
The hinge sits within a cup, the cup is rebated into jamb or directly into the wall, the hinge is then fastened to the cup. As a result, if the door needs to come down, all you do is unscrew the locking bolts and remove the hinge from the cup.
The door can be removed and reinstalled for painting and adjustments without damaging the walls render, timber or paint work, saving time and money.
To adjust the door simply adjust the position of the door via the settings within the hinge. This adjustment is done without the door coming down.
For Cupboard Doors
The invisible hinge is also available for cupboard doors. The adjustable concealed cupboard hinge is revolutionary in its design and is rated to carry a 24kg cupboard door to 180° opening aperture.
Cupboard doors no longer need to be visually interrupted by the traditional butt hinge where the two leaves of the hinge meet and protrude out past the jamb.
The door can be removed and reinstalled for painting and adjustments without damaging timber or paint work, saving time and money.
You can simply adjust the position of the door via the settings within the hinge. This adjustment is done without the door coming down.
In public buildings, due to the high opening & closing frequencies of the doors, it is recommended to always calculate the door to be heavier than it actually is. Better to over spec the door than under spec it, even if the weight and size of the door does not require a third or fourth hinge.
The Fourth Hinge
In some cases, the use of a fourth hinge may be required for achieving long-term hinge reliability.
Placing a fourth hinge in support of the upper (top) hinge, which is where the main traction forces are applied, will ensure long-term hinge reliability.
In cases of a large door with widths (>900 mm) or heights (>2100 mm) when different forces are produced by the leverage effect of the doors movement and centre of gravity change.
A fourth hinge must be installed in the upper part of the door, only in this position can it positively affect the weight capacity of the hinge.
Concealed Hinges Appeal
Using concealed hinges allows for the formal architectural composition of a wall to now continue without interruption, creating an aesthetically appealing appearance that is truly clean and elegant.
