Our Products

EPS is a material formed when polystyrene is vapor-foamed and has excellent thermal insulation properties. It is suitable for a variety of applications, such as construction and refrigeration.

The flame-retardant rating of rockwool is up to class A. Our prefabricated rockwool sandwich wall panels provide a tight fit when spliced and offer excellent sound and thermal insulation.

The edges are sealed with PU, enhancing overall panel sealing. It can prevent rainwater from entering more effectively, prolonging the service life of the entire panel.

Prefabricated polyurethane sandwich panels are a popular choice for construction projects. It has low thermal conductivity and can be used for a variety of applications, including insulation, fire protection, and more.

Polyisocyanurate belongs to a kind of PU, and the content of isocyanurate in its composition will be higher, which has advantages in structural strength and heat resistance.

Prefabricated glass wool sandwich panels consist of glass wool and metal, which are combined with a high-strength and fire-resistant bonding agent. Prefabricated glass wool sandwich panels perform well in fire protection, thermal insulation, and environmental protection.
Sustainability and Environmental Protection
For the pentane foaming of PU panels, Pupanel uses a process that does not add F11 or 141B. Thus the fabrication process can achieve zero fluorine emissions. In addition, you can also choose prefabricated wall panels made of aluminum panels or environmentally friendly materials, such as EPS and glass wool. All of them are recyclable and meet sustainability requirements.

Applications

Prefabricated sandwich wall panels can be used as internal partitions or external walls. It has the advantages of light weight, quick installation, and good heat preservation.

Prefabricated sandwich panels are easy to clean and effectively seal the clean room from air infiltration. It meets the high hygiene and temperature requirements of clean rooms.

Prefabricated sandwich panels can also be used in cold rooms to maintain a stable, low-temperature environment and reduce the burden on the refrigeration system.

For temporary buildings such as site offices, it offers quick installation and easy dismantling.

Prefabricated sandwich panels can also be used for warehouse perimeter walls, increasing structural strength and reducing construction time.
- Our Factory
- Project Case
The biggest advantage of prefabricated wall panels is that they are pre-produced. Thus, they can reduce the hassle and time costs associated with on-site production. Moreover, its strength and performance are reliable. That is why prefabricated wall panels are not only suitable for projects with tight delivery cycles but can also be used in many construction projects to increase efficiency.
The installation of prefabricated wall panels requires you to come on-site to make the positioning, connections, and dimensional adjustments. Then, you can fix them with concealed or open nails. The process is usually straightforward. However, cleaning the wall surface before installation is also important to prevent impurities from disrupting the flatness of the prefabricated wall panels to be installed.
Generally, prefabricated wall panels are not produced for temporary use. They have a lifespan of about 20-30 years with proper use and maintenance. If your project is exposed to corrosion, prolonged sunlight, or physical wear and tear, its lifespan may be reduced.
When properly shipped and packaged, prefabricated wall panels are generally not subject to wear, tear, or bending during transportation. Of course, you can also rest assured that Pupanel has specialized export experience. We have shipped more than 112,845,311 prefabricated sandwich panels worldwide. We will make sure that you receive the products with satisfactory packaging and excellent quality. In addition, we can provide on-site installation guidance and technical support.
Yes, prefabricated sandwich panels can be used as both exterior and interior walls. They are typically designed to be waterproof and weatherproof, and have enough structural strength to provide long-lasting support for your project.
What are Prefabricated Wall Panels?

Prefabricated wall panels are manufactured in a factory and delivered to the installation site. Unlike a concrete or brick wall that is poured on site, this process is prefabricated, and all you need to do is adjust the shape and size to suit the site layout.
Pupanel’s sandwich panels are a type of prefabricated panel widely used in industrial and commercial buildings, providing heat insulation, safety, and fire prevention.
Prefabricated Wall Panel Functions
Structural Support
Prefabricated wall panels can be installed within a wall to provide structural support and enhance stability.
Insulation
If your project requires insulation. Then you can choose precast wall panels with lower thermal conductivity to better insulate the exterior and maintain a stable temperature within the space.
Soundproof
Some prefabricated wall panels also absorb noise, such as PUR/PIR/asbestos sandwich panels.
Work as a Barrier

Prefabricated wall panels can be used as a building barrier to insulate the exterior from rain, snow, dust, and to protect the interior.
Advantages Of Sandwich Panels as Prefabricated Wall Panels
Lightweight And Efficient
The efficiency of the prefabricated panels’ insulation ability is usually not dependent on the thickness, so if you need the same level of insulation, sandwich panels are usually much lighter and thinner than concrete or gypsum boards.
More Efficient Construction
Prefabricated sandwich panels are typically manufactured in a factory. So when you need it for a real project, you only need to install and fix it on site. This significantly reduces construction time, labor costs, and material costs.
Easy And Fast Installation
Prefabricated sandwich panels are preassembled, and installation requires only splicing and fixing; no additional skills are required.
Fire Resistant
For commercial buildings such as hotels, precast sandwich panels are fire-resistant, enhancing safety.
Low Cost

In terms of price, precast sandwich panels can be significantly less expensive than precast concrete walls or plasterboard, further reducing the cost of ownership.
Prefabricated Sandwich Panels vs Precast Concrete, Gypsum
The Precast Concrete Panels
Precast concrete panels are also a type of precast wall panel. It is a wall panel material that is pre-poured and reinforced with steel in the factory. It can act as a weight-bearing element within a building, providing greater structural strength.
The Prefabricated Gypsum Panels
Prefabricated gypsum panels are gypsum materials that are poured and molded in a factory. They are usually lighter than concrete panels and can be used as interior partitions. However, because they are not waterproof and have limited durability, they are not usually used as exterior walls.
The Comparison
| Features\Types | Sandwich panels | Precast Concrete Panels | Prefabricated Gypsum Panels |
| Weight | The lightest | Higher | Medium |
| Thermal Insulation | Self insulated | Poor thermal insulation can be used with sandwich panels | Poor thermal insulation, also can be used with sandwich panels |
| Installation Speed | Fast | Slow | Slow |
| Service Life | Up to 20-30 years | The Longest | Shortest |
| Applications | Warehouses, cold rooms, and many areas | Common constructions | The interior walls of commercial or other buildings |
Technical Parameters of Prefabricated Wall Panels To Notice
The Thickness

In fact, the thickness of prefabricated sandwich wall panels affects many of its properties, such as thermal and acoustic insulation, overall strength, and other properties. You can choose based on your specific thermal or acoustic insulation needs. 50-75mm is a common thickness for a wide range of applications, while thicknesses of 100mm and above are mostly used in areas where lower temperatures must be maintained.
Core Density
On the other hand, density determines the weight of prefabricated wall panels and is measured in kilograms per cubic meter. Higher density means more weight per unit. This is an important parameter when your project must account for the weight of the panels or when lightweighting is required.
Thermal Conductivity
Thermal conductivity is a critical parameter when choosing prefabricated wall panels for your project. Its unit is W/(m · K), which represents the amount of heat that can pass through a unit area per unit weight. The lower the value, the stronger the insulation performance and the better the heat retention in actual use. You can combine the thickness and thermal conductivity in the product parameter table to make a selection.
