The PUF sandwich panels, a major component in PEB structures, are being widely used in different industrial applications because they provide all such features that we mentioned. It has found its application in warehouses, factory buildings, cold storage units, and more such commercially relevant structures.
In this blog, we’ll learn about 5 reasons why PUF roofing panels and other types of panels made from polyurethane foam are getting popular for industrial buildings in India.
The primary benefit of using PUF sandwich panels is its amazing thermal insulation property. These panels are made of polyurethane foam, or PUF. This material is sandwiched between two metal sheets.
This combination offers amazing thermal resistance, so that a building stays cool in summer and warm in winters naturally, as compared to traditional concrete structures. The high insulation that these panels provide is quite useful where temperature regulation is crucial.
For example, it is quite useful for structures like clean rooms, cold storage buildings, laboratories, and more.
PUF sandwich panels are lightweight and durable, which makes them easy to transport and handle. This reduces both labour cost and installation time.
As compared to the traditional methods of cement construction, installing the PUF roofing panel for such applications takes a lot less time, which makes it very helpful when there is a tight project deadline.
With this, these panels become great for both temporary structures such as toilet blocks and guard rooms. Also, they are suitable for large projects like aircraft hangers and terminal buildings. In both cases, time is of greater essence.
When planning a structure, make sure you convey your timeline and demands with PUF panel suppliers because it will help them prepare or customize the panels as per your requirements and timeline.
PUF Sandwich Panels are highly durable and resistant to environmental factors such as moisture, wind, and UV radiation.
They can also resist the corrosion that chemicals, salt, and pollutants cause to a structure over time. For building facades, warehouses, and structures in coastal areas, corrosion can be a big concern. PUF panels will reduce the need for frequent repairs because of their strength and durability.
This resilience makes them an excellent choice for industrial sheds, factory buildings, and other outdoor structures that require materials that can withstand harsh weather conditions.
PUF panels are versatile and can be customized to suit a wide range of industrial applications. They are available in various sizes, thicknesses, and finishes, catering to the specific needs of different sectors. Whether it is for constructing industrial enclosures, poultry sheds, control rooms, or multi-level car parking, PUF Sandwich Panels provide flexibility in design and construction.
This adaptability ensures that the panels can be used effectively in diverse settings such as noise-proof enclosures, GIS buildings, and even high-traffic areas like shopping complexes and stadiums. As a leading PUF panel manufacturer, EPACK Prefab has supplied these panels for numerous large-scale projects across India, reinforcing their utility and versatility.
PUF sandwich panels offer a variety of advantages for industrial buildings. For example, it has amazing insulation, long-lasting durability, customization options, and sustainability. These panels offer versatile solutions for warehouses, cold storage, factory buildings, and other commercial structures.
In the last few decades, sandwich panels have proved to be a revolutionary solution in the construction industry.
By definition, this material is a self-supporting component that serves two concurrent purposes – partitioning (roof or wall) and thermal insulation.
The sandwich panels vary by:
Every panel consists of several layers: core with thermal insulation, steel claddings (external and internal) and coatings protecting from mechanical damage and corrosion.
For example, let’s compare two popular technologies used in warehouse building construction.
In the first case the external partitions consist of double brick walls, while in the second case they consist of sandwich panels.
By selecting the first case we have to order the following works: wall construction, thermal insulation installation and, finally, external layer installation.
By selecting sandwich panels, the construction process is far less complicated and thus quicker and, most importantly, cheaper. Panels are finished components, suitable for easy installation, e.g. to a steel structure.

Considering the present situation on the construction services market, working time plays a key role in the cost optimisation process. The quicker the structure is completed, the less we spend on construction service costs, which have increased significantly in recent years. The rapid structure completion process also translates to earlier commencement of occupancy, which improves the return on investment for business projects.
Sandwich panels are available in three basic variants. Each uses a specific panel core. Thus there are materials with cores made of polyurethane, mineral wool and EPS. Each of these solutions is intended to meet specific needs.
Polyurethane is the best and most commonly used thermal insulation material on the market. After many years of market domination by older materials, such as mineral wool or EPS, today they are being replaced by better equivalents in the residential construction market, in the form of panels made of hard polyurethane foam – Thermano.
Sandwich panels with this core are primarily distinguished by better thermal insulation properties. The lambda of 0.022 W/mK has no equal, meaning that this type of material is selected by project owners seeking to reduce the total heating costs.
Another benefit of using this type of panel is the potential to save space inside the building. Better thermal insulation of the partitions translates to lower wall thicknesses, compared to other types of panels or masonry, while maintaining the same thermal insulation parameters.
Another equally important benefit is the lower density of the material from which the core is made (40 kg/m3). This simplifies installation significantly, because no special tools or equipment are required on the project site.
The second type of panel has two advantages – fire resistance and soundproofing efficiency. One feature of mineral wools is their behaviour in fires. Selected panels manufactured by Balex Metal are EI 240-rated, meaning that both the sealing and the fire rating of the partition is maintained for 240 minutes. This is enough time for people to leave the building safely as well as minimising the potential losses resulting from the fire.
Another important feature is to have a partition designed to prevent the transmission of excessive noise. The best panel versions feature good soundproofing capabilities, which in practice translates to a soundproofing effectiveness of up to 33 db.
The history of sandwich panels began with EPS (polystyrene). However, this type of core has been gradually replaced by mineral wool and, primarily, by polyurethane.
If we compare all three types of panel, EPS lies between the mineral wool and the polyurethane in terms of thermal insulation properties; however it is inferior to mineral wool in its reaction to fire.
Sandwich panels with an EPS core are, in turn, a budget solution that can be used successfully whenever there are no stringent requirements for fire resistance or thermal insulation.
It is also possible to join the panels. This applies to the panel types featuring polyurethane or mineral wool cores. This is possible both for panels with exposed fasteners (standard type) and concealed fasteners (type plus).
Apart from the basic functions of industrial structures, attention is increasingly being paid to aesthetics. The look of our place of business, whether it be a warehouse, manufacturing plant, store or car showroom, often determines the level of trust in the brand. This is why adding unique character by the project owner to the project has become so important.
Balex Metal provides many interesting solutions, with a range of profiles, coating types (e.g. mat) and cladding colours (more than 30 different colours).
A range of selected designs can be connected freely, which can give spectacular results that attracts attention and highlights the type of business, whether the style is more classical or modern.
Due to the non-porous surface, sandwich panels are quick and easy to clean. Standard pressure washers are perfect for this purpose. The panel coating materials are completely resistant to water jet impact, thus regular cleaning will keep the structure looking new for many years.
Balex Metal panels are available with a full range of accessories. These include flashings (in any colour, including the panel colour) and all kinds of fasteners to allow panels to be fitted to any substrate (steel, reinforced concrete or wood). The project owner can also choose from a wide range of seals and gaskets to ensure the highest sealing of the partitions.
When choosing sandwich panels, the best possible access by light should also be considered. This can be provided by small windows made of polyester, which are also available with dedicated flashings. Thanks to this, the result is an appealing and well-protected structure that protects against external conditions.
Sandwich panel structures can be freely arranged. The material is easy to process, so buildings can be designed with windows and gates wherever required.
In travelling the length and breadth of Europe, you cannot miss the hundreds of structures made using sandwich panels. Interestingly, today these are not only industrial structures. Residential projects are becoming increasingly popular, with many design offices even creating ready concepts based on such applications.
Sandwich panels are available in wall and roof versions, which are typical for the following types of structures:
