Our 50mm Sandwich Panels
PU sandwich panels are among the most widely used. It provides a balance of thermal insulation, load-bearing, and weather resistance, and is suitable for most situations.
PIR has a higher isocyanurate content than PU and therefore has a more stable internal structure and greater heat resistance, making it suitable for environments with higher temperature control requirements.
EPS is made from vapor-expanded polystyrene, which is self-extinguishing, weather-resistant, and lightweight. The metal panels can be made from aluminum. Moreover, EPS is UV-resistant for roofing applications and has a service life of up to 20 years.
Rockwool is a Class A fire-rated material, suitable for use in places where fire resistance is critical, such as chemical plants where flammable and explosive substances are present. It is also an environmentally friendly material that can be coated with new steel for use in corrosive environments.
Features of Pupanel ‘s 50mm Sandwich Panels
Pupanel ‘s 50mm sandwich panels are low-density, lightweight, and easy to install.
Optional C/E/H styles of splicing, easy and tight splicing.
Strong metal surface and stable internal structure.
PIR, PUR, EPS, and Rockwool all have low thermal conductivity and can effectively block heat transfer between hot and cold air.
More Robust Connector Design
Pupanel is always realizing constant innovations in sandwich panels and is committed to improving its quality. Our 50mm panels use a double-support plug structure that is internationally patented. The inclusion of reinforcement washers improves panel support and makes the panel-to-panel connection tighter and stronger. Enhance the wall’s overall wind resistance.
Meeting diverse bending needs
Pupanel has introduced two JoRNS AG bending machines equipped with intelligent features, including zero error, automation, and servo control. The machines can process multi-tapered sheets. They can deliver a diverse design for your 50mm sandwich panels and meet multiple bending requirements. Add more customization options to meet your needs.
More Efficient
In most cases, sandwich panels can insulate more efficiently without requiring excessive thickness. A 50 mm thick PUR/PTR sandwich panel has been tested to have no more insulation capacity than a 75 cm thick concrete panel. In comparison, it is a highly efficient material that balances structural strength, lightness, and thermal insulation, making it suitable for large factories, logistics centers, and other areas where both thermal insulation and energy efficiency are required.
Applications of 50mm Sandwich Panels
A 50mm sandwich panel can be used in the walls of industrial buildings for basic thermal and noise insulation. Its lightweight design reduces the load on the walls and is suitable for larger buildings.
In commercial buildings, a 50mm Sandwich Panel can be used for partitions and walls. It is lightweight and easy to install, reducing construction time and lead times.
For cold chain storage, 50mm sandwich panels are also suitable. It maintains warehouse temperatures that are not subject to extreme cold and is less costly.
Sandwich panels with a thickness of 50mm are suitable for retrofitting old building walls. Because it is lightweight, it only needs to be spliced and installed onto the surface of the wall. There is no need to restructure the interior of the wall.
- Our Factory
- Project Case
Yes. When used as a wall, 50mm sandwich panels provide basic thermal and acoustic insulation. When used as roofing panels, their outer sheet metal layer is waterproof and prevents water vapor from penetrating.
Generally speaking, correctly installed 50mm sandwich panels can withstand wind speeds of 40 m/s without damage, making them suitable for most outdoor environments.
However, this ability is affected by several factors, including material, density, and sheet thickness. If you are in an area with high winds or harsh conditions, contact us to adopt a reinforced design or select a thicker sandwich panel.
In most cases, 50mm sandwich panels can effectively block heat exchange between the indoor and outdoor environments, reducing the burden on your cooling/heating system. For office buildings, warehouses, and general factories with less stringent temperature control, this feature is perfectly adequate and also ensures comfort in daily use.
Actually, 50mm sandwich panels are ideal for these situations:
- Buildings that do not require extreme insulation;
- Projects that require lighter panels;
- Projects needing faster installation;
- Costs and budget considerations；
- Areas with a moderate climate;
- Temporary structures such as containers.
What is a 50mm Sandwich Panel?
50mm sandwich panels have an overall thickness of 50 mm. This thickness can effectively balance cost, structural strength, insulating performance, and installation convenience, so 50mm sandwich panels are sufficient for most applications.
Today, its production process is sufficiently mature. The 50mm sandwich panels are suitable for most applications where there is no need for extreme heat or sound insulation.
What Functions Can 50mm Sandwich Panels Provide?
Insulating The Heat
For non-extreme conditions, 50 mm sandwich panels can provide sufficient insulation to reduce the burden on the air conditioning system and realize energy savings.
Wind Resistant
Its external fixed metal panels can help block rain and wind for 50mm sandwich panels. This thickness is sufficient to withstand wind pressure without damage. At the same time, it can prevent cold air from entering the room, maintaining a stable indoor temperature.
Absorb The Noise
Basic soundproofing is also available. It can absorb non-extreme external or internal noise and ensure a comfortable level of comfort in the room.
Prevent The Flame
50mm sandwich panels can also be used to meet commercial and industrial safety requirements related to fire protection, where you need to choose sandwich panels with a B1/B2 or A rating. In addition to this, you can choose between different core materials (PUR/PIR/EPS/Rockwool) depending on the specific fire protection requirements.
50mm Sandwich Panels vs 100mm Sandwich Panels
Compared with 100mm-thick sandwich panels, 50mm-thick sandwich panels are lighter, faster to install, and less costly. It is suitable for general applications, including remodeling old buildings and most factories.
But from the point of view of insulation requirements, thicker 100mm sandwich panels have a better insulation capacity, in the cold chain transportation, and from the point of view of long-term energy costs of buildings with high insulation requirements, 100mm sandwich panels perform better.
| Features\Types | 50mm sandwich panels | 100mm sandwich panels |
|---|---|---|
| Cost | low | higher |
| Weight | light | Almost twice as much as the 50 mm ones |
| Installation hardness | Easy and fast | More complicated |
| Insulating ability | Suitable for most applications | Higher than 50mm sandwich panels |

How To Choose The Right Thickness Of The Sandwich Panels?
Thickness generally affects the insulation, structural strength, and cost of sandwich panels, so the choice of thickness can be based on your budget and usage requirements:
- If you have low thermal requirements and a limited budget, you can choose 25-40mm sandwich panels, which are commonly used for interior partitions and similar applications.
- When your project is in a normal climate zone, and you need to balance performance and cost, 50-75mm sandwich panels are a more cost-effective choice.
- For projects located in extremely cold areas or with higher performance, energy consumption, and thermal requirements, PIR or rockwool sandwich panels with thicknesses of 100mm, 200mm, or more will be a more cost-effective choice.
