Rockwool Blanket 100mm with wire-mesh reinforcement and a high density of 100 kg/m³ is a heavy-duty insulation solution designed for demanding thermal, acoustic, and fire-safety applications. Manufacturers produce this blanket from premium mineral wool fibers spun from natural basalt rock and bonded into a dense, resilient mat. The added galvanized wire mesh provides mechanical strength, dimensional stability, and long-term durability, making this product ideal for industrial, commercial, and high-performance building environments.

With a thickness of 100mm, this Rockwool blanket delivers superior insulation performance where thinner materials fall short. It creates a deep, continuous barrier that significantly slows heat transfer, efficiently absorbs sound, and withstands harsh operating conditions. Engineers, contractors, and consultants often specify this product for critical installations where performance, safety, and longevity are non-negotiable.

Rockwool Blanket 100mm: High-Performance Thermal Insulation

The 100mm thickness combined with a 100 kg/m³ density gives this Rockwool blanket excellent thermal resistance. The tightly packed mineral fibers trap still air within the structure, reducing heat transfer through roofs, walls, ducts, and industrial equipment. When installed correctly, the blanket minimizes heat gain in hot climates and limits heat loss in temperature-controlled spaces.

This makes it especially suitable for:

• Industrial pipework and vessels operating at high temperatures
• HVAC ducting where energy efficiency matters
• Roofs and ceiling voids exposed to intense solar heat.
• Mechanical rooms, boiler rooms, and plant facilities

By reducing unwanted heat transfer, the insulation helps lower energy consumption, stabilize internal temperatures, and protect adjacent building elements and personnel from excessive surface heat.

Rockwool Blanket: Exceptional Acoustic Insulation and Noise Control

Rockwool’s dense fiber structure also delivers strong acoustic absorption. At 100 kg/m³, this blanket effectively dampens mid- to high-frequency noise while also contributing to overall sound reduction across a wide range. It converts sound energy into low-level vibrations within the fiber matrix, reducing echo, reverberation, and noise transmission.

This makes the product highly effective in:

• Generator and compressor rooms
• Industrial plants and factories
• Mechanical shafts and service risers
• Auditoriums, churches, and large halls
• Commercial buildings requiring controlled acoustics

When used behind cladding, gypsum boards, perforated sheets, or metal casings, the blanket significantly improves the acoustic performance of the entire system.

Fire Resistance and Safety Enhancement

Rockwool blanket 100mm with mesh offers outstanding fire-resistant properties. Mineral wool is non-combustible and can withstand very high temperatures without melting or emitting toxic fumes. In fire-prone or regulated environments, this insulation adds an important layer of passive fire protection by slowing the spread of heat and protecting structural and mechanical components.

The wire mesh reinforcement ensures the insulation remains in place even under thermal stress, making it suitable for applications where insulation failure could pose safety risks. This feature is particularly valuable in industrial plants, ducts, chimneys, and service installations where fire resistance and mechanical stability are critical.

Wire Mesh Reinforcement for Strength and Longevity

The integrated wire mesh distinguishes this Rockwool blanket from standard unfaced or lightly bonded insulation. The mesh:

• Provides tensile strength and structural support
• Prevents sagging on vertical or overhead installations
• Allows secure mechanical fixing using pins, ties, or banding
• Maintains insulation integrity over long service periods

This reinforcement makes installation easier and more reliable, especially on large ducts, tanks, vessels, and pipework. It also improves resistance to vibration, airflow pressure, and movement common in industrial environments.

Practical Installation and Handling

Despite its high density and thickness, the 3m × 1m blanket remains practical to handle on site. Installers can cut it accurately using insulation knives or serrated blades. The blanket wraps smoothly around curved surfaces and conforms well to irregular shapes while maintaining consistent coverage.

Contractors typically secure it using:

• Mechanical pins and clips
• Stainless steel or galvanized bands
• Wire ties and mesh stitching
• External cladding or jacketing systems

For exposed applications, installers often finish the insulation with aluminum foil cladding, stainless steel sheets, or protective coatings to enhance durability, moisture resistance, and appearance.

Durability in Harsh Conditions

Rockwool blanket 100mm with mesh resists high temperatures, mechanical stress, and aging. It does not rot, shrink, or degrade under normal service conditions. The mineral fibers do not support mold growth or pest infestation, making the product suitable for long-term installations in demanding environments. With proper protection from water ingress, the insulation maintains its performance for many years.

Typical Applications

Rockwool insulation blankets are best applicable.

• Industrial pipe and vessel insulation
• High-temperature ducting and exhaust systems
• Power plants, factories, and processing facilities
• Generator rooms and heavy machinery enclosures
• Commercial HVAC systems with strict energy targets
• Acoustic and thermal treatment in large technical spaces

For industrial, commercial, and high-specification building projects, this Rockwool blanket stands out as a robust, dependable insulation solution built to perform under pressure.
