Description
Rock Wool Fireproof Panel of Panel Sandwich Group is the only one in the market that can resist a possible fire against flames. In this way, a very useful reaction time and capacity is achieved. Manufactured under all the necessary safety measures and with the best quality materials.
This fire resistant Rock Wool Panel is formed, as the rest of sandwich panels, by a double metallic coating of galvanized and pre-lacquered steel that encloses and protects an insulating core of Rock Wool fibers. Thanks to its multi-fiber structure, it offers excellent fire resistance. This added value that we add to our roofing panels has allowed us to work with professionals and individuals who needed to protect their works from the fear of possible fires. It is usually installed in commercial environments, bakeries, wood ovens, schools, chemical industries, hospitals where safety is a priority above all.
Our Rock Wool Fireproof Sandwich Panel for roofing is composed of 5 Frets on the outer face in such a way that it provides an even greater resistance with less amount of supports. On request, we can also manufacture roofs with two corrugations, always with exceptional resistance, protection and thermal insulation wherever it is installed.
- One of its main qualities is its installation, they take advantage of the waves overlap each other and are screwed directly to the existing structure.
- We manufacture made-to-measure rematerial to protect the areas where the rock wool is exposed, thus increasing even more the useful life of the fireproof panels.
- Possibility to choose from a wide variety of colors: Pyrenean White RAL 1006, Navarra Green RAL 3000, Silver Metallic RAL 9006 and many more.
- All quality and fire resistance certificates available to customers.

The insulation of the Rock Wool Panel is of variable thickness, manufactured in different thicknesses according to clients’ needs. The insulations or insulation coefficients are equal to or higher than those shown in the table. The weights and coefficients correspond to the Fireproof Rock Wool Panel for a High-Density roof.
Panel´s weight resistance according to distance
| Overload (kg/m²) | Distance (m) |
| 80 | 5.76 |
| 100 | 5.16 |
| 120 | 4.48 |
| 150 | 3.66 |
| 200 | 3.77 |

The specific example case on the Fireproof Rock Wool Sandwich Panel´s table of loads or resistance, of its high density, is based on 80 mm thickness with two or more support points. The values in the table depend on the core thickness and thickness of the sheets used. The values are those that meet at least, having point loads that support more than shown. For more information or specific resistance tables according to the panel configuration, you can request it from the commercial.
Characteristics
The main advantage of Rock Wool over other traditional panels is its fire protection. Nowadays, we not only for the price of the products, but we also have to look at those that offer us added value. That is the case in Panel Sandwich Group; for your roofing, we offer an insulating rock wool core panel, the only one on the market that does not ignite and in case of a possible fire, allows great time reaction.
Being manufacturers, we can adapt the production schedule of the Fireproof Rock Wool Sandwich Panels to your needs and preferences. For this, we provide Fire-resistant Roofing Rock Wool Panels in thicknesses of 30, 40, 50, 60, 80, and 100 mm, that offer fire resistances of 30, 60, and 120 minutes. However, by request and under conditions, we also offer the possibility to increase the thickness to 200 mm.
The Fireproof Rock Wool Sandwich Panel has gained popularity, in recent years, due to its quick and easy assembly process. The fixation between one rock wool plate and the other is done by overlapping and screwing directly to the structure at the meeting between the two. In addition, we will provide the specific screws for all types of surfaces together with the special washer (cappelletti) with a neoprene gasket to prevent leaks.
The Fire-resistant Rock Wool Sandwich Panel has a fire behavior cataloged as REI 30, 60, and 120 for the panels of 50, 80, and 100 mm, respectively: this means that its mechanical strength, R; its impermeability to gases, E; its thermal insulation, I, are guaranteed during those periods. In addition, it also has a fire resistance certificate A S2 B0, the previous M0, not polluting when burned. These values have been obtained through official tests per current Spanish regulations, meeting or exceeding the parameters established in the European framework.
Sandwich Panel Installation process
Accessories and endings
FRONT SHOT
The front cover protects the insulating polyurethane core when it is exposed on the front of the roof for sandwich sheet roofs, thus ensuring maximum performance over a long period of time. In order to provide a total aesthetic integration, it is manufactured in the same finish as the five frets Sandwich Panels.
SIDE TRIM
The lateral finish covers the polyurethane foam that is exposed on the side of the roof plates; a very vulnerable point in front of precipitations and humidities that damage the insulating core and therefore reduce the performance of the installation. The lateral finish prevents these damages with a simple installation.
SIDE WALL FINISHING
The lateral wall finish covers the meeting between the side of the sandwich sheet roof and the adjacent wall, which continues above the roof and , therefore, slip water that seeps into the insulating core of the Sandwich Panel Cover or even the inside the building, causing serious damage.
WATER PIPE
The water pipe collects the precipitations that fall on the roof sheets and evacuate them separately, avoiding the problems that usually cause the water curtains. It is a very simple installation that allows highlighting the qualities of the Sandwich Panels at a minimum price.
TOP RIDGE TO WALL
When the cloth of a sandwich cover starts from a higher wall, it is recommended to install the ridge cap to the wall to provide better sealing against leaks and humidity. In addition, it is manufactured in the same color as the Sandwich Panel at the lowest price m² for extraordinary performance.
