Why insulated panels used in cold rooms?
What are insulated panels and why are they used in cold rooms? What kind of materials are they made of? We try to answer all these questions in this article.
There are different types of cold rooms depending on the exact storage needs. Over time, we have seen many changes in refrigeration equipment and cold room customization. One of these modifications was the addition of insulated panels. So first of all you might ask: What is an insulated panel?
What is an insulated panel?
Basically, in refrigeration insulation, in addition to selecting the appropriate refrigeration door, the use of an insulating panel consists of a rigid core protective layer between two layers of structural board. The core can be made of XPS or EPS and the structural board can be plywood or cement. These panels are widely used in cold rooms to maintain the temperature inside the structure, prevent air leakage and increase the strength of the structure.
Various building material components are combined with SIP. These panels can be used on floors, exterior walls and roofs. We can use these panels to solve many different problems. Insulated panels are commonly used in cold rooms and refrigerated vehicles. Insulated panels are widely used for thermal insulation all over the world.
Cold Room Basics
A cold room can store a variety of goods such as frozen goods, fine chemicals and so on. The design and implementation of cold storage can be quite challenging. The following three elements make up a modern cold room:
Interconnected freezer walls
These walls are actually thermal panel walls and are designed to eliminate any possible gaps in the structure.
The concept of flooring is to prevent heat transfer from the floor surface. Many floors today are twice as insulated and sealed.
The roof is a sensitive area that must be protected from heat transfer because it is more exposed to sunlight. As a solution, it can be double-insulated to protect it from external heat.
In short, you can get comprehensive insulation for your structure using thermal insulation installed by a major thermal insulation company. Thermal panels, walls and floors work well to balance the environment. Materials have properties for transferring heat from each other.
For example, steel is a metal that can be very hot and cold and has the ability to transfer temperature to any surface around it. Here, a thermal insulation system is created that can prevent this heat transfer by keeping heat away from the insulation.
Dimensions and features of insulated panels
In general, these panels are available in small pieces because they will be easy to transport. The thickness of insulated panels that are to be installed in cold rooms usually varies between 4 and 12 inches. EPS is the most popular foam used in insulated panels, measuring 3.5 inches of foam in a 4.5-inch-thick panel.
The best way to use insulated panels in a cold room is when building. This way you can save extra money. Building a structure with insulated panels eliminates several building materials and proves to be a good way to save money.
Also, as far as strength is concerned, it provides the strength and stability of good structures, so that it also protects the building during natural damage. Also, this panel is environmentally friendly so you are also protecting nature.
Insulation materials used in cold storage
The cold store, whether located in retail stores or a test chamber for scientific applications, needs to maintain the correct condition, starting with the insulation materials used to build the unit. Several options are explored here. KPS Global uses it in freezer coolers as well as in science rooms due to its strong thermal performance of polyurethane foam. We also use expanded polystyrene for large refrigerated warehouses because it is a cost-effective option and its extra depth is usually not a problem.
Polyurethane is a closed cellular insulating material that has low thermal conductivity. This material expands and hardens upon cooling, and is usually used on site. This foam requires specialized equipment and proper technical training to ensure that it is sprayed properly. This material is commonly used in walk-in freezers and walk-in refrigerators or specialized applications. Read more about in-depth comparisons of foam types for more information on selecting closed-cast and in-shed polyurethane by KPS Global.
Polystyrene is a cellular foam insulator. This material has two classifications: expanded polystyrene foam (EPS) or extruded polystyrene foam (XPS).
EPS is a lightweight option that also has thermal properties. It is cheaper than polyurethane but requires twice the width to achieve the same thermal R values as polyurethane. KPS Global uses this type of foam in our continuous line panels.
XPS is a closed cell insulation that is made in various shapes and then shaped into rectangular ingots. This material is commonly used in industry but is lower in terms of its ability to maintain thermal performance for a long time.
Installation of insulated panels in cold rooms
Installation depends more on the size and type of cold storage. Cold room panels are more needed in cold rooms with a large area. Cold room kits are available that provide a complete description of the installation of insulated panels. The following are prerequisites for starting the installation process:
Insulated panels for measuring wrench and screwdriver wrench
The first step after assembling all the tools is to make sure you choose the right type of panels for your building. This is why having the right amount of PU panel thickness is so important because they are fixed in the target areas. Use a measuring tape and measure the ceilings and walls correctly.
All measurements must be very accurate, including corners and spots in the walls with any leaks or holes in the mouse. You can then cut the insulation panels according to the measurements to fit them perfectly. Now comes the installation phase. Start by installing the panels in the corners and then cover the center. Allen key will help to fix the lock correctly.
You need to make sure that the locks are fully secured as loose locks will open slowly over time, causing gaps and loss of energy. Maintaining the right temperature in cold rooms is quite challenging, especially when you do not have the technical knowledge. If in doubt, you can contact a thermal insulation company and they will introduce you to a professional and experienced cold room installer to do it for you.
In the end, it is clear that insulated panels provide the strength and stability of your cold rooms. Although they have drawbacks, such as IPs that can be damaged by moisture, many manufacturers are unaware of this technology, and quality problems and expensive ventilation systems are major limitations. However, this technology is very popular because of its speed, economy and environmental friendliness. This technology uses approximately 60% less wood than conventional construction. It is also recommended to use insulated panels in cold rooms as much as possible to create balance in the interior and product quality.
Also, as we all know, cold rooms, apart from thermal insulation, must also be able to control bacteria, grease and dust. Therefore, they must be chosen wisely to make the structure resistant to pests and dust. Insulated panels must have a minimum value of R up to 40 and must have high thermal efficiency. The thickness should be between 2 and 12 inches. Finally, when buying insulated panels, you should consider the durability of the panels in terms of strength, weight and easy installation mechanism.
