Rock Wool Slab / Roll – Cold Insulation Material

Product Type: Mineral Wool (Stone Wool / Rock Wool)
Form: Slabs or Rolls
Application: Cold insulation, thermal control, condensation prevention, acoustic insulation, and fire-resistance in industrial and HVAC systems.

1. Product Description

Rock Wool Slab/Roll is a high-performance mineral fiber insulation made from basalt rock and other natural minerals melted at high temperature and spun into fibers.
It is manufactured in slab or flexible roll form, often coated with facings such as:

• Aluminium foil (FSK / AL Foil)

• Glass cloth

• Black tissue or white tissue

This insulation is widely used in cold and low-temperature piping, tanks, ducts, and equipment where both thermal insulation and condensation control are required.

2. Physical & Chemical Characteristics

(Typical industry values; may vary by manufacturer)

3. Functional Advantages

• Excellent thermal insulation for cold pipelines, tanks, and HVAC systems

• Condensation and moisture-control when used with proper vapor barriers

• Non-combustible, enhancing fire safety

• Good acoustic insulation

• Chemically inert and resistant to mold, fungi, and pests

• Dimensional stability over a wide temperature range

• Easy installation in flat or curved surfaces (rolls are ideal for pipes/ducts)

4. Typical Applications

Rock Wool Slab/Roll Cold Insulation is used in:

• Cold and chilled water pipelines

• HVAC air-handling units and ducts

• Refrigeration lines and cold storage facilities

• Industrial process equipment

• Storage tanks and vessels

• Building and commercial insulation (acoustic & thermal)

• Sandwich panels or metal cladding systems

5. Product Forms Available

• Slabs (Rigid/semirigid):
  Used for tanks, walls, equipment, panels

• Rolls (Flexible blankets):
  Ideal for pipelines, ducts, curved and uneven surfaces

• Faced products:

  • Aluminium foil / FSK for cold & vapor-barrier applications

  • Glass cloth for high-temperature or industrial use

6. Storage & Handling (General Notes)

• Keep the material dry, protected from weather and moisture.

• Store in original packaging until use.

• Maintain products in clean conditions to preserve vapor-barrier facings.

Our Rockwool Building Foil Roll is a high-performance, reinforced aluminum foil laminate designed as a perfect vapor barrier and reflective insulation layer. It is specifically engineered to be used with Rockwool insulation slabs in building walls, roofs, and ducts.
