When it comes to modern construction, sandwich panels are among the most versatile and high-performing solutions. But how do you choose the right one? There is no single answer, as every project has different needs. In this guide, you’ll discover step by step how to pick the most suitable panel, considering applications, materials, regulations, and sustainability.

What do you need the panel for?

The first question to ask yourself is simple: where and how will the panels be used?
Whether it’s for an industrial warehouse, a logistics center, or a technical laboratory, it’s important to identify:

• Whether it’s for roofs, walls, floors, or partitions.
• If the environment is indoor or outdoor, humid, corrosive, noisy, or at high fire risk.
• If it concerns a new building or a renovation.

The more details you have, the easier it will be to identify the right panel.

Insulation: thermal, acoustic, or both?

One of the main reasons for choosing a sandwich panel is insulation. But which type do you need?

• If your goal is to maintain a constant temperature, go for panels with PIR or PUR: lightweight, high-performance, and ideal for roofs and walls.
• If, instead, you work in noisy environments and/or need better fire resistance and reaction, mineral wool is the best choice.

Each material has its own characteristics, and the choice depends on the context in which it will be installed.

Safety first

In some sectors, fire behaviour is not optional, but a mandatory requirement.
Mineral wool panels, for example, offer a fire reaction class of A2-s1,d0, among the highest available, and good EI or REI fire resistance values.
Even PIR panels can offer good performance, with classifications up to B-s2,d0 REI 30.

Always check the EI or REI certifications, fire reaction and make sure the product complies with current regulations.

Regulations and certifications not to be overlooked

A panel can be technically perfect, but if it’s not certified, you risk problems during testing or receiving low scores in sustainable projects.

Look for panels with:

• CE marking
• Declarations of Performance (DoP)
• Declaration of conformity
• FM certifications
• Suitability for CAM requirements

These documents ensure the product meets European and international standards.

Installation and maintenance: how easy is it?

A well-designed sandwich panel installs quickly and lasts over time.
Some models allow you to cover up to 1000 m² per day, reducing time and costs.
Furthermore, they are self-supporting, compatible with photovoltaic systems, and require minimal maintenance.

Finishes and environmental resistance

If you work in corrosive environments, such as the food or chemical industry, choose panels with:

• Plastic-coated surfaces
• Special paints
• Stainless steel
• Fiberglass

These finishes protect the panel and extend its useful life.

Sustainability: a responsible choice

More and more companies are choosing panels produced with renewable energy and recycled materials.
At ItalPannelli, for example, we use energy produced by the photovoltaic systems installed on our warehouses and electric heat pumps in place of fossil fuel thermal plants, promoting low-impact environmental practices.

We also manufacture products with recycled content from our raw materials, metal supports, PIR, and mineral wool (MiWo).

If your project aims for sustainability, choose panels that respect the environment without compromising on quality.

Choosing the right sandwich panel isn’t complicated—it’s just a matter of knowing what to look for.
Understanding the application, materials, regulations, and performance will help you make a conscious and long-lasting choice.
