Rockwool Panel: the isolation your work demands

The Sandwich Panel was born to be installed in industrial environments. But with the passing of the years and its development, it has become more popular, being installed in many different places: from industrial warehouses, chemical industries, roofs for residential houses, farms and for any type of cold storage. It also allows the incorporation of different materials, as is the case of rock wool. The Rockwool Panels combines the excellent qualities of sandwich panels with the properties of Rock Wool in a same product!

What is Rock Wool?

Construction in the USA is constantly evolving, and one of the great advances in this sector over the last century has been the use of Rock Wool as a construction material. But before delving into the multiple possibilities this mineral offers, it's important to briefly understand its origin.

Like many other important discoveries throughout history, the discovery of Rock Wool or Mineral Wool was somewhat accidental. In the early years of the 20th century, a group of volcanologists found a strange mineral fiber hanging from the trees near the Kilauea volcano in Hawaii. When it erupted, they observed how this material was generated when the lava was acted upon by the wind. Over the years, thanks to technological and industrial development, Rock Wool has been perfected in factories, developing techniques that allow obtaining the insulator directly.

What is Rock Wool made of?

Today, Rock Wool is manufactured in Colombia through a process that seeks to imitate the natural action of volcanoes. At temperatures above 1,600 °C, basaltic or volcanic rock is melted in a furnace to return it to its original state of lava. Then, the lava is poured onto wheels that spin at high speed and, thanks to centrifugal force, it is transformed into fibers that will be compressed more or less depending on the desired performance. Finally, this "mattress" goes to the final curing phase, where it acquires its definitive shape.

At Sandwich Panel Group, we are committed to innovation and research to provide the best products. For this reason, we have a solution that combines the best of Rock Wool with the benefits of Sandwich Panel installation. Yes, we are talking about the Rockwool Sandwich Panel!

The model that is most successful in the USA, which we will further develop later, is Acoustic Rockwool. But at Sandwich Panel Group we also have fireproof Rock Wool panels that do not burn when they come into contact with fire.

In the construction sector, the main use of Rock Wool is as insulation due to its excellent properties. By combining the utilities of Rock Wool with the properties of the Sandwich Panel, we obtain as a result the Rock Wool Sandwich Panel, which offers high-quality thermal and acoustic characteristics, as well as excellent fire behavior.

Therefore, it is highly requested for use in home construction, as it is a material that can be installed in various areas of our homes.

Throughout our long experience, we have participated in several projects that have required the installation of the Rock Wool Sandwich Panel both on the roof and on the facade. The installation of this material is much easier than the independent installation of Mineral Wool, because the properties of the Sandwich Panel facilitate the assembly process.

The installation process of the Rock Wool Sandwich Panel will depend on whether it is a roof or a wall. In both cases, a perfect union is achieved that avoids the appearance of leaks.

Acoustic Rockwool Panels

All our Acoustic Rockwool Panels offer great acoustic protection with a noise level reduction of up to 35dB. This is because Rock Wool fibers have sound-absorbing qualities, allowing for a quieter and more comfortable environment.

The Acoustic Rock Wool Facade is widely used in buildings and facilities where sound insulation is a priority, such as schools, hospitals, offices, residential buildings, and more. It effectively reduces noise transmission from the exterior to the interior of the building, thereby enhancing the comfort and usability of the space.

Its durability and resistance to environmental conditions also make it a suitable option for outdoor applications. It withstands harsh weather conditions, providing long-lasting performance without the need for significant maintenance.

Fireproof Rockwool Panels

Another significant aspect of the Rock Wool Sandwich Panel is its fire-resistant properties. This fireproof rock wool is made from inorganic materials that are naturally resistant to high temperatures. Therefore, it does not burn when it comes into contact with fire and does not produce toxic smoke or gases.

This makes it an excellent choice for buildings where fire safety is a top priority, such as industrial facilities, warehouses, and public buildings. The fireproof Rock Wool Panel can resist temperatures of up to 1000 degrees Celsius, providing a significant level of protection against fire hazards.

At Sandwich Panel Group, we are proud to offer Rock Wool Sandwich Panels that combine superior thermal and acoustic insulation with fire resistance.

Benefits of the Rockwool Sandwich Panels

Although the advantages that our Rockwool Panel can bring to your project are numerous, here are the main benefits if you decide to install this material:

Thermal Isolation

Its excellent insulating attributes make it possible to achieve an excellent level of thermal comfort. The low level of thermal conductivity of the mineral fibers that compose it, together with its multidirectional structure containing dry air inside, constitutes a barrier to heat flow.

Acoustic Isolation

It is the thermal insulating material with the best acoustic isolation levels. Greater acoustic comfort translates into improved health.

Fire resistant

Contributes to increase the fire resistance of the building. It slows down the spread of fire, allowing to gain time in case of fire.
It is used to fill air chambers where there are chimney ducts or other types of elements that can reach very high temperatures. Classification A1 against fire.


RockWool is a material that is permeable to water vapor. That is to say, it allows water vapor to pass through, reducing the possibilities of humidity formation due to condensation.

No absorption of humidity

By insulating facades and roofs, we avoid the formation of humidity due to condensation, since the dew point is not reached. It does not absorb humidity. Very suitable in cases where there is a lot of moisture due to condensation.

Wind protection

It allows the filling of joints and gaps in the walls, which prevents the generation of cold air currents towards the interior of the home that can lower the temperature of the house.


It is a highly resistant material, with the capacity to retain all of its properties for an estimated useful life of 50 years. In addition, it can withstand the effects of weathering and other environmental factors, making it ideal for use on roofs and walls.


Rockwool is a 100% recyclable product with no loss of properties.
