Light Weight Construction Material Board Fireproof and Heat Insulation Rock Wool / Mineral wool Sandwich Panel

Panel facings are made of galvanized steel sheet, coated with polyester paint, thickness from 0,4 to 0,6 [mm] as options. The steel we use to produce our panels are delivered by biggest world steel concerns.

The core of the panel can be made of polyurethane foam (PUR) or (PIR) with density of 40 kg/m3, mineral wool with density of 100 kg/m3 or 85 kg/m3 (LITE) or expanded polystyrene (EPS) produced by our own factory.

When pressed into rolls and sheets, the individual fibers’ exceptional heat conductivity is matched by their superior sound absorption and insulation qualities due to their ability to divide air. Although they are not impervious to the effects of a sufficiently hot fire, materials such as fiberglass, stone wool, and ceramic fibers are frequently used in construction when passive fire protection is needed. These materials are used as spray fireproofing, in stud cavities in drywall assemblies, and as packing materials in firestops.
It can also be used in resin-bonded panels, brake pads, automotive plastics, filler in gasket compounds, filtering media, and hydroponic growing media.

The process of producing mineral fibers is the same; no binder is used. For its reinforcing properties, the fiber itself is utilized as a raw material in many different applications, including coatings, plastics, gaskets, and friction materials.

Performance:

  • 1. Steel buildings are now more fireproof overall since their flame resistance level has reached level A.
  • 2. Polyurethane foams are inserted into the tongue-and-groove on both edges, effectively preventing heat conduction and rain leakage, preventing moisture absorption from reducing strength and thermal insulation performance, and enhancing the durability of both fireproof and thermal insulation performance.
  • 3. Greater thermal insulation performance is ensured by the high volumetric weight core material (glass wool has a volumetric weight of 64 kg/m3, whereas the volumetric weight of rock wool is > 120 kg/m3).
  • 4. To increase the tongue-and-groove’s overall strength and stop it from deforming, stiff polyurethane foams are injected into its two sides.
  • 5. The fireproof wool undergoes a 90° rotation, increasing its strength by 50% and positioning the fiber perpendicular to the panel.

1.What is Rockwool sandwich panel?

The fireproof rock wool sandwich panel is made of two layers of color-coated steel plates or other metal plates. The rock wool is bonded with the metal panel to form beautiful, flat, rigid, and tough building panels.

2.How thick are Rockwool sandwich panels?

Our thickness for rockwool is 50, 75, 80, 100, 150, 200mm,and density range is 80 – 150 KG/M³.

3.  How many kg is Rockwool insulation?

Rockwool refers to a type of thermal insulation made from actual rocks and minerals. A wide range of products can be made from this. material because of its superior ability to block heat and sound.
