Rock Wool Blanket Product Specifications

Surface Options

Everinsulation offers rock wool blanket in two standard facing configurations, with additional customization available upon request:

1. Plain Rock Wool Blanket (Unfaced)

The plain rock wool blanket features an unfaced, flexible surface suitable for internal insulation applications where the insulation layer will be covered or enclosed. It provides excellent thermal and acoustic performance in its simplest form and is ideal for:

• Internal pipe and duct insulation

• Equipment cavities and enclosures

• Multi-layer insulation systems

• Applications requiring maximum flexibility

2. Aluminum Foil Faced Rock Wool Blanket

The aluminum foil faced rock wool blanket incorporates a reflective aluminum foil layer bonded to one side of the blanket. This facing provides additional benefits:

• Enhanced moisture protection – Acts as a vapor barrier, preventing moisture ingress

• Heat reflection – Reflective surface improves thermal performance by reducing radiant heat transfer

• Increased durability – Provides mechanical protection during installation and service

• Easy cleaning – Smooth surface resists dust accumulation

This version is ideal for:

• Outdoor piping and equipment

• HVAC ductwork

• High-humidity environments

• Applications requiring a clean, finished appearance

Custom Facing Options

Everinsulation also offers custom facing solutions including:

• Fiberglass cloth facing

• Stainless steel mesh facing

• Laminated scrim reinforcement

• Custom adhesive backing for specific installation requirements

Main Applications

Rock wool blanket is a versatile insulation solution suitable for a wide range of industrial and construction applications:

1. Industrial Boiler and Large Equipment Insulation

Boilers, heat exchangers, and large industrial equipment generate significant heat that must be contained for safety and efficiency. Rock wool blanket conforms easily to equipment contours, providing complete coverage and consistent thermal performance.

2. Oil and Gas Pipeline Wrapping

Pipelines in oil, gas, and petrochemical facilities operate at high temperatures and require reliable insulation to maintain process temperatures and protect personnel. Rock wool blanket wraps easily around pipes of all diameters and can be layered for additional thickness.

3. HVAC Duct Insulation

Heating, ventilation, and air conditioning ducts benefit from rock wool blanket insulation, which reduces thermal losses and provides acoustic damping for quieter operation. Aluminum foil faced options are particularly suitable for HVAC applications.

4. Building Curtain Wall and Roof Insulation

In commercial and industrial construction, rock wool blanket provides thermal and acoustic insulation for curtain walls, metal roofs, and façade systems. Its non-combustible nature enhances building fire safety.

5. Sound Absorption and Noise Reduction Projects

Industrial facilities, power plants, and manufacturing sites rely on rock wool blanket to absorb equipment noise and create safer, more comfortable working environments. The material’s high sound absorption coefficient makes it effective for both airborne and impact noise reduction.

6. Insulation for Irregular Surfaces and Complex Equipment

Tanks, valves, flanges, turbines, and other complex equipment geometries are challenging to insulate with rigid materials. Rock wool blanket adapts to these shapes, ensuring complete coverage without gaps or thermal bridges.

7. Marine and Offshore Applications

Rock wool blanket is widely used in marine environments for engine room insulation, fire-rated bulkheads, and piping systems. Its resistance to vibration, moisture, and high temperatures makes it suitable for demanding offshore conditions.
