What is PU Sandwich Panel

A PU Sandwich Panel is a three-layer construction product consisting of two coloured galvanized steel sheets and core between them. PU Sandwich Panels possess good aesthetic properties, excellent energy saving characteristics, as well as can quickly assembled and thus are widely used for construction of trade and office buildings, prefabricated frame buildings, including warehouse complexes, industrial objects, and agricultural structures.

Advantages of PU Sandwich Panel

Thermal Insulation And Energy Saving, Cost-Effective
As a thermal insulation material, the coefficient of thermal conductivity is 0.023w/(m•k). PU Sandwich Panel has a thermal insulation effect twice that of EPS and three or four times that of other thermal insulation materials, which ensures better thermal insulation efficiency. In practice, this effectively keeps the building absorbing heat and brings enormous economic benefits.

Fire Retardant
PU Sandwich Panel has self extinguishing property, and flame retardant is added in the production process, so that it can more effectively resist the attack of fire. Even if the instantaneous temperature reaches 250 ℃, it can be calmly dealt with.

Sound Insulation And Air Tightness
The air tightness of PU Sandwich Panel is very good, which can effectively absorb sound. In particular, the office buildings in downtown areas are bustling outside, and excellent privacy space must be effectively guaranteed.

Prevent Rusting And Corrosion
The PU Sandwich Panel has a large span and is waterproof and moisture-proof, so it is not easy to rust. And its service life shall be at least 20~50 years. It shall be installed once and used for life. The most important thing is that they do not need additional maintenance and care and are always in the best condition.

Fast Construction
The production of PU Sandwich Panel is highly efficient, reducing the waiting period for construction. It saves time for the enterprise, which is equivalent to increasing the income of the enterprise in disguised form.

Types Of PU Sandwich Panels

PU Sandwich Panels For Facades
The variety of finishes of sandwich panels make them a very popular choice for facades. They have the advantage that the final result is very aesthetic because the fixings are hidden. Other advantages are their lightness, modularity and high insulation performance. This type of panels is mainly used to insulate facades and walls, as well as interior walls. They are suitable for industrial buildings, sports centres, residential and public buildings.

PU Sandwich Panels For Roofs
In this case, the panels, unlike those for facades, are highly exposed to the action of rain, snow or wind, as well as to their weights. They are installed on roofs and decks of all types of buildings, although they are most commonly used on roofs with a minimum slope of 7%. Their installation is usually combined with watertight joints, which makes installation quick and easy and does not reduce the insulation of the roof. Self-drilling screws are also used to fix them to the structure, and sealing systems are used to prevent water seepage. The most basic models of sandwich panels for roofs do not have a finish that embellishes the outside. For this reason, there is the option of the tile-type sandwich panel, which has a sheet metal covering that offers an appearance similar to a ceramic tile. Thus, it is mostly used in residential buildings.

Refrigeration PU Sandwich Panels
The panels are also used to insulate temperature-controlled spaces, such as cold rooms or freezers. In these cases, the types of sandwich panels used are thicker in order to withstand very low temperatures. They offer optimum insulation and are easy to install.

How To Maintain PU Sandwich Panel

Regularly Check The Appearance And Connection Parts
Regularly check the appearance of the PU Sandwich Panel, especially whether the surface is damaged, cracked or dented. At the same time, pay attention to check whether the connection parts and the sealing seams are tight to ensure that there is no air leakage or water leakage between the sandwich panels.

Waterproof Treatment And Anti-Corrosion Measures
PU Sandwich Panels are used in parts such as building exterior walls. Attention should be paid to waterproof treatment to ensure that they can effectively prevent moisture penetration in rainy weather. In addition, in a humid environment, to prevent the corrosion of the sandwich panels, anti-corrosion coatings or other related measures can be used.

Protection Of Fire Resistance
PU Sandwich Panels have certain advantages in fire resistance, but in order to ensure their long-term effectiveness, it is recommended to conduct regular fire resistance inspections. The use of fire retardant coatings and flame retardants can increase their fire resistance and improve safety.

Avoid Collisions And Scratches With Sharp Objects
Try to avoid collisions and scratches with sharp objects on PU Sandwich Panels. Although PU Sandwich Panels have a certain toughness, excessive physical damage may affect their appearance and performance.

Clean Up Debris And Dust Regularly
Regularly clean up debris and dust on the surface of the sandwich panel to keep its surface clean. The accumulation of dust and dirt may affect the appearance of the PU Sandwich Panel and reduce its thermal insulation performance to a certain extent.

Applications of PU Sandwich Panel

Portable Structures

PU Sandwich Panels are used to create portable structures such as temporary offices, shelters, andexhibition stands. They can be easily transported and assembled, making them ideal for use in outdoor events andconstruction sites.

Manufacturing Process of PU Sandwich Panel

Material Feeding
The process begins with the feeding of the core material (PU foam) and the outer metal sheets into the machine. The metal sheets are typically unwound from coils, while the PU foam is supplied in the form of liquid chemicals that react to form the foam.

Roll Forming
The metal sheets pass through a series of rollers that shape them into the desired profile. This process is known as roll forming and is crucial for ensuring the panels have the correct dimensions and geometry.

Panel Assembly
Once the metal sheets are formed, they are combined with the PU foam core to form a PU Sandwich Panel. The core material is injected between the two metal sheets, and the panel is assembled under pressure to ensure a strong bond between the layers.

Curing
After assembly, the panels are moved to a curing oven where they are subjected to heat and pressure. This process helps the PU foam to cure and bond with the metal sheets, resulting in a rigid and stable panel structure.

Cutting and Stacking
Once the PU Sandwich Panels have cured, they are cut to the desired length and stacked for further processing or packaging.

Frequently Asked Questions

Q: Is installing PU sandwich panel Efficient?

A: The efficiency that comes with using PU sandwich panels is high. Their quick installation not only saves time but also minimizes on-site disruptions, a crucial factor in the fast-paced construction industry.

Q: Do PU sandwich panel need Precision Fit for Optimal Performance?

A: During installation, the precise fit of PU sandwich panels is paramount. This attention to detail minimizes gaps, ensuring an airtight seal and enhancing overall performance, especially in temperature-controlled environments.

Q: What is the advantages of PU sandwich panel?

A: First of all, as a thermal insulation material, the outstanding performance of polyurethane is definitely reflected in its low thermal conductivity. If the thermal conductivity is considered alone, PU Sandwich Panels are currently the best thermal insulation materials. Second, PU Sandwich Panels have good flame retardancy and low combustion coefficient, which can effectively prevent the spread of fire in house fires, and their anti-combustion performance can reach B1 level. Third, this type of panel is also waterproof and corrosion-resistant when combined with other panels, and its service life is much longer than that of ordinary panels. Fourth, the panel is elegant and beautiful in shape, and it is very simple to install, which can greatly shorten your construction period. It is precisely because polyurethane panels have so many superior properties that this type of panel is currently widely used.

Q: What are Things to note when purchasing PU Sandwich Panels?

A: 1. Appearance: The appearance of PU Sandwich Panels is smooth and should not have obvious defects such as dents, bubbles, extrusion, scratches, cuts and honeycombs.

2. Thickness: The thickness of PU Sandwich Panels should meet the requirements of the selected standards.

3. Size: The size of PU Sandwich Panels should meet the requirements of design documents and construction drawings.

4. Hardness: When purchasing PU Sandwich Panels, you should pay attention to their hardness. The higher the hardness, the greater the strength, so it can enhance the quality and service life of the panels. 5. Density: Density is an important parameter of the quality of PU Sandwich Panels, which can be obtained through quality testing and other methods.

Q: What are the application scopes of PU Sandwich Panels?

A: The application scope of PU Sandwich Panels is very wide, mainly including the following aspects:

1. Wall insulation and roof insulation: As a building exterior wall insulation material, it can improve the building insulation performance and save energy; as a roof insulation material, it can avoid rainwater leakage and reduce high temperature energy consumption in summer.

2. Cold storage and refrigeration equipment insulation: The excellent thermal conductivity of PU Sandwich Panels makes it the preferred material for insulation and heat insulation of cold storage, refrigeration equipment, etc.

3. Sound insulation and vibration isolation: PU Sandwich Panels have good sound insulation and vibration isolation performance and are widely used in engineering, offices, computer rooms, sound isolation and other fields.

4. Fire room: The fire resistance performance of PU Sandwich Panels meets the B-level standard and is widely used in the walls, roofs and other parts of fire rooms.

Q: What are the 6 testing methods for PU Sandwich Panels?

A: 1. Measure the length, width and thickness.

2. Measure the surface flatness.

3. Take a small piece and step on it, then put it under the faucet and pour water on it, then squeeze it with your hands to see if you can squeeze out water.

4. Calculate the specific gravity. The density of 35-45KG/cubic has the best insulation effect. Note that before measuring the specific gravity, you should look at the cross-section of the PU Sandwich Panel and rub it with your hands to see if there are any particles falling off. If it is serious, this PU Sandwich Panel cannot be used.

5. Look at the color. It should foam evenly and be slightly yellowish in color; it can be pressed with fingers. If it is too hard, it is not foamed well and the insulation effect is not good.

6. Observe the flame retardancy, cut off the edge material and burn it, then let it leave the fire source to see if it can extinguish itself away from the fire. If it can extinguish itself after leaving the fire source, it can be used.

Q: Is the thicker the PU Sandwich Panel, the better?

A: Flame retardancy is very important: the core of the PU Sandwich Panel is made by foaming a combination of polyether and polymerized MDI (polyphenyl polymethylene polyisocyanate). The quality of the polyurethane core does not lie in its thickness, but in its flame retardant properties.

Q: How to improve the flame retardancy of PU Sandwich Panels?

A: There are usually three ways to improve the flame retardancy of PU Sandwich Panels: adding flame retardants (mainly phosphorus and halogen flame retardants); increasing the isocyanate index in the formula, that is, increasing the amount of black material (MDI); increasing the flame retardancy of the material through molecular structure modification technology. The addition of flame retardants can easily increase the smoke production and toxicity of polyurethane foam when it burns, and the flame retardant is easy to migrate and fail over time. Therefore, the improvement of the performance of polyurethane foam plastics is mainly achieved by adjusting the components of polyurethane rigid foam combined polyether. The performance of polyurethane rigid foam combined polyether will directly affect the process performance of polyurethane rigid foam production and the physical properties and usage characteristics of the final product. The foam thermal conductivity, density, strength, hardness, flame retardant properties, etc. can all change with the different formulas of polyurethane rigid foam combined polyether raw materials.

Q: What should be paid attention to when using PU Sandwich Panels?

A: 1. Fire prevention: PU Sandwich Panels are flammable to a certain extent, so you need to pay attention to fire prevention when using them. You can set up fire isolation belts and use fire retardant coatings for fire prevention. 2. Moisture-proof: PU Sandwich Panels are not water-resistant, so you need to pay attention to moisture-proof when using them.
