Types of Joints For Wall Insulated Panels

Types of Joints For Wall Insulated Panels


Recently, we have received a few inquiries from a customer in South Africa regarding the types of joints for our wall panels. Particularly regarding the difference between our four types of joint and their use.
We have four types of joints that are available for our sandwich panels for the wall:
  1. Concealed fixation joint;
  2. Visible fixation joint;
  3. Visible fixation cold-room joint;
  4. Hermetic joint.


The most used type of cladding panel around the world has an invisible or hidden fixation, which means that once installed, you won’t be able to see the screws.
How does it work? The tongue and groove joint hosts the screw and then covers it with the overlapping insulated panel. This system is often used in facades or cladding of buildings.

The visible fixation joint is a popular tongue and groove joint, where the fixation stays apparent. Reliable, resistant, and easy to install. It’s essential not to over-fasten the screws, as this will deform the panel’s surface. 


It exists a version of the visible joint that we have specially designed for cold-room walls and ceilings: the Frigo or Labyrinth joint. The insulated panel with the Frigo’s joint offers a double and more rooted tongue and groove joint to prevent air leaks. It’s also known as the Labyrinth joint because of its complex shape. The most exciting feature is that in this joint, you add different types of sealant, depending on the environment and on the temperature of use, making it virtually leak-proof. Here you can find the Advantages of Labyrinth – Joint on Cold – Room Insulated Panels

The type of joint that offers the best hermeticity is the Hermetic joint. It is a visible or apparent fixation insulated panel that installers use when they want perfect hermeticity. It comes with a female-female joint: on the building site, the installer will add a special flashing and a spacer, then inject the foam directly into the joint. The result will be a seamless wall, as it was a whole panel without joints, totally leakproof.
