Acoustic enclosures with rock wool sandwich panel: protection, insulation and resistance for your pavilions

In environments where noise and safety are key factors —such as in industrial, logistics, or urban areas— acoustic enclosures play an essential role. At Okatent we are committed to high-performance materials such as the rock wool sandwich panel, an effective solution to guarantee thermal comfort, sound insulation, and fire resistance in your modular pavilions.

What is a rock wool sandwich panel?

The rock wool sandwich panel is made up of two metal sheets that encapsulate an insulating core composed of mineral fibers of rock wool. This type of enclosure is characterized by its excellent fire behavior (with certifications such as EI120 or even EI240) and its high acoustic insulation capacity, making it the ideal choice for covering both walls and roofs.

Within the range of sandwich panels, this option stands out for its resistance and efficiency.

If you are wondering what rock wool is, it is an insulating material made from melted volcanic rock, which is spun to form a fibrous mass. This structure gives it thermal, acoustic, and fire-protection properties.

In addition, you can consult the certificates of Okatent pavilions that guarantee quality, warranty, and environmental management.

Outstanding properties of rock wool

Rock wool is obtained from melted volcanic rocks, mainly basalt, transformed into fine fibers through high-temperature centrifugation. Thanks to this structure, it offers several essential advantages for modular construction:

  • Excellent thermal insulation:
    Its fibrous composition retains air inside, minimizing heat transfer. This improves energy efficiency indoors in both warm and cold climates.
  • High acoustic performance: At absorbs vibrations and significantly reduces sound propagation, a key advantage in industrial, educational, or sports environments.
  • Non-combustible behavior: Rock wool does not burn or drip when exposed to fire. It is classified as a non-combustible material (Euroclass A1) and can withstand temperatures above 1000 °C without losing its properties.
  • Durability and stability: It retains its shape against changes in temperature or humidity, does not deform, and does not easily degrade over time.
  • Breathable but water-repellent: It allows water vapor to pass through, preventing condensation, but does not absorb liquid water, helping to keep the interior of structures dry.
  • Sustainable and safe: It is manufactured with abundant raw materials and can be recycled. In addition, it is not attacked by fungi, bacteria, or pests.

These properties make rock wool not only an effective option, but also a safe and sustainable one for pavilions that require comfort, environmental control, and regulatory compliance.

LR DUAL panel: maximum thermal protection and certified fire resistance

Within the range of panels with a rock wool core, we highlight the LR and LR DUALmodels, specifically designed for enclosures with high thermal performance and fire protection.

The LR DUAL panel, especially suitable for space partitioning
, is composed of pre-lacquered galvanized steel sheets and a high-density rock wool core (120 kg/m³). Its structural design with lamellas arranged perpendicularly to the faces of the panel improves rigidity and mechanical performance.

In addition, it is certified with Euroclass A2-s1,d0 and offers fire resistance of up toEI 180 and integrity of up to 240 minutes in thicknesses ≥100 mm.

Advantages of using rock wool panels in acoustic enclosures

Side and roof enclosures made withrock wool panels offer both technical and functional benefits:

Noise reduction

Thanks to their porous composition and density rock wool sandwich panels allow a reduction of up to 35 dB, helping minimize noise propagation in noisy facilities such as factories, workshops, or urban sports centers.

Maximum fire protection

One of the most valued aspects of this material is its fire behavior. If you are wondering
whether rock wool is flammable, the answer is no: it is a non-combustible material, which makes it possible to meet strict safety regulations. Due to its fibers and organic composition, flames do not ignite. It can achieve fire resistance classifications of up to EI240, making it ideal for critical facilities.

Thermal comfort

Its low thermal conductivity improves insulation against extreme temperatures, reducing energy consumption and contributing to the interior comfort of the pavilion.

Durability and mechanical resistance

The panel offers great structural strength, allowing its installation as a fixed enclosure without losing rigidity against impacts or overloads.

Although it offers multiple advantages, it is also important to know the disadvantages of rock wool.. In some cases, handling may generate dust that is irritating to skin or mucous membranes, so appropriate protection is recommended during installation. In addition, although it is highly resistant, it is not the lightest material on the market, which can influence certain projects.

In addition to acoustic enclosures, at Okatent you can also find solutions ranging from fixed sides such as trapezoidal sheet metal and operable enclosures in aluminum, to folding ones such as tensioned fabric sides.

Recommended applications

Rock wool sandwich panel enclosures are especially useful in:

  • Industrial warehouses with heavy machinery.
  • Logistics pavilions in urban areas.
  • Sports facilities, such as padel courts or gyms.
  • Commercial spaces requiring interior sound control.

  • Educational centers or coworking areas, where concentration is a priority.

Sandwich panels in Okatent enclosures

At Okatent, our enclosures are designed to offer customized and efficient solutions. The self-supporting metal panel with a rock wool core is available for both side and top enclosures, adapting to the structural design of our modular pavilions.

This is the most efficient side in the entire catalog. It protects against noise, weather, and fire with a single panel.

In addition, we guarantee the quality of all our products with certifications such as ISO 1090, ISO 14001 and compliance with European structural Eurocodes.
