Features of 75mm Sandwich Panels
The raw materials (PUR/EPS/rock wool, etc.) used in the production of 75mm sandwich panels have low thermal conductivity, which effectively blocks heat transfer.
The JoRNS AG bending machine enables high-precision bending, resulting in more uniform mechanical properties in the 75mm sandwich panel and greater structural stability.
The core material is fire-resistant and meets the fire protection requirements of different buildings.
C/E/H-type and other physical splicing methods; the combination is simple but very close.
The sandwich structure can absorb sound and reduce noise.
All materials for the 75mm sandwich panels are of moderate density, which will not impose an excessive mass burden during installation.
Take EPS 75mm sandwich panels, for example; they offer good weather resistance and can last up to 20 years without fading.
Excellent thermal insulation effectively blocks heat conduction between indoor and outdoor spaces, reducing building energy consumption.

More Wind Resistant
Pupanel’s 75mm sandwich panels feature a unique double-support plug-in interface. This design improves wind load distribution and is internationally patented. Your panels can be spliced more tightly. They can also significantly increase the wind protection rating of your walls in high-wind areas, extending their service life.
Applications of 75mm Sandwich Panels
75mm sandwich panels are suitable for cold rooms or freezers where temperature control is not required. They reduce heat exchange between the room’s interior and exterior, maintaining low temperatures, reducing the load on the refrigeration system, and saving energy.
75mm sandwich panels can be used in warehouse applications for structural support, thermal insulation, waterproofing,g and moisture resistance. Warehouse 75mm sandwich panels can be used as prefabricated wall panels to reduce construction time. It enables logistics centers, industrial warehouses, and other buildings to be brought online quickly.
75mm can provide thermal and acoustic insulation and improve room comfort within the common residence. Its lightweight makes handling effortless and fast.
In modular buildings, such as site offices and containers, 75mm sandwich panels are the ideal material. They are stronger than 50mm sandwich panels and avoid the costly waste of using 100mm sandwich panels, which is important for medium to long-term projects.
- Our Factory
- Project Case
While thinner sandwich panels are generally suitable for temporary projects, 75mm sandwich panels are better suited to projects with a long life cycle and related requirements for thermal performance, structural stability, and cost. It can strike a balance between these factors. It is widely used in large-scale factories, logistics centers, and commercial buildings.
Compared with sandwich panels around 25mm or 50mm, 75mm offers better performance, including thermal conductivity and bending resistance. While 100mm sandwich panels offer greater insulation capacity, 75mm sandwich panels are more cost-effective.
Yes, we offer customization services, including:
- Core material (PU/PIR/EPS/rock wool/glass wool)
- Metal panels (aluminium/steel)
- Surface coating (galvanized finish)
- Dimensions
- Steel plate color
The sound insulation performance of 75mm sandwich panels is influenced by several factors, including the core material and density. If you have high requirements for sound insulation, you can choose sandwich panels made of rock wool or glass wool in terms of the material. Finding panels with higher density values on the product parameter sheet will also help.
Yes, 75mm sandwich panels have a recyclable core and surface panels, which can be recycled by separating the panels from the internal foam structure. The outer metal panels can be remelted into new products,and the inner polyurethane or PIR foam can be used in waste incineration. Rockwool can be reused as a building filler for insulation and more.
What is a 75mm Sandwich Panel?
This is a sandwich panel with an overall thickness of 75mm. It is one of the more conventional materials available today. It is suitable for most thermal insulation and basic soundproofing applications.
The 75mm sandwich panels are constructed by sandwiching insulation material between two layers of metal panels. The core material is usually chosen from PUR, PIR, EPS, rockwool, or glass wool, while the outer panel is typically steel, aluminum, or other metals. You can also choose different coatings for these panels, such as galvanized steel, depending on the required corrosion resistance.

How to Choose the Right 75mm Sandwich Panel?
Consider The Environment and Climate Of The Region
You can choose 75mm sandwich panels based on the environmental and climatic conditions at your project site. For example, if your project is located by the sea and is exposed to salt spray, choose sandwich panels with a 180g galvanized coating; if it is in an acidic or alkaline environment, aluminum panels with a 150g galvanized coating are more suitable.
If the building is in a cold or hot area, choose 75mm sandwich panels with low thermal conductivity. PUR, PIR, and EPS perform well in this regard.
Determination Of Panel Application
It is equally important to determine the exact location and role of your 75mm sandwich panel application.
For wall panels, your 75mm sandwich panels must be adequately supported and water- and moisture-resistant.
If your sandwich panels will be used for roofing, choose lightweight, durable materials. For example, EPS retains its color under UV exposure and has a service life of up to 20 years.
If your sandwich panels will be used in a cold room, choose 75mm panels with lower thermal conductivity.
Work With a Reliable 75mm Sandwich Panels Manufacturer
Of course, you need to work with a reliable manufacturer. You can achieve this by verifying their business qualifications, production experience, and product certifications. For 75mm sandwich panels, please confirm whether they are certified to CE, FM, ISO 9001, etc.
Finally, you should be aware of the after-sales services the supplier can provide, which are equally important for ensuring a positive purchasing experience.
