Choosing the right kind of joint and panel for a cold room is as important as considering any other aspect during cold room installation.
These joints can be the make or break factor in your installation because they provide the much-needed airtightness and support to the entire room.
Even if you are not dealing with a cold room, you should be familiar with different types of joints that are suitable for PU panels and other types of panels used in the construction process. This knowledge will help you in making smart decisions and achieving the results you need by proper installation of the panels with suitable joints.
Let’s discuss these joints one by one:
Concealed fixation joint is the most popular type of joint used in cladding panels all over the world. These panels have an invisible and hidden fixation. It simply means that once the panels are fixed, there will be no screws visible to you.
The working of the concealed fixation joint is quite simple. The screw is located in the tongue and groove joint. It is covered by the overlapping insulated panel. This kind of system is typically used in the cladding of buildings.
The visible fixation joint is another famous tongue and groove joint. However, in this joint, the fixation is visible. It is popular in different buildings and cold rooms because it is reliable and easy to install.
An important tip regarding the installation of a visible fixation joint is that the screws should not be over-fasten because they can end up deforming the surface of the panel. You can choose to use both visible fixation joint or the following labyrinth joint for a cold room.
Visible fixation cold-room joint is a version of the visible fixation joint to make it more suitable for cold rooms. It is commonly used by PU panel suppliers in PU panels for cold rooms. This joint is also known as the Labyrinth joint due to its complex shape. The benefit of using labyrinth join with the PU panel is that it provides a more firm and rooted tongue and groove. As a result, air leaks are prevented in the cold room.
You also have the option of adding different types of sealants in this joint to adjust the usage as per your environment and temperature needs. Some of the other benefits of visible fixation cold-room joint in PU panel for cold rooms are:
As the name suggests, the hermetic joint is known for providing the best hermeticity. It is also a type of visible fixation that PU panel suppliers use when they want the cold room to be perfectly airtight. It is coupled with a female-female joint.
Moreover, the installer will have to insert an additional flashing and a space on the building site to ensure proper installation of the hermetic joint. Ultimately, the best result is achieved because it seems like that the entire wall is a single panel without any joints. It will be airtight and leak-proof that is important for the safety and freshness of the products.
The discussion above on the different types of joints for the PU panel should help you understand the basics of these joints and panels. The final choice is always dependent on your specific requirements and the kind of results you want to achieve with these joints.
Now that you are familiar with the four popular types of joints, you should have no issue choosing the best joint according to your requirements.
