Rockwool Blanket
Rockwool Blanket: the flexible insulation solution
A flexible, non-combustible, water-resistant insulation solution, Rockwool blanket delivers superior fire resistance, thermal and acoustic insulation, and long-term energy conservation across industrial and commercial projects. Made from natural rock and recycled materials heated into a molten mixture and spun into fine wool, Rockwool blanket resists temperatures up to 1,093°C, making it one of the most reliable insulation materials available for demanding applications.
With 20+ years supplying Rockwool insulation to industrial and commercial projects across Queensland and Northern NSW, All Insulation & HVAC Supplies has the product knowledge and stock availability to support your project from quote to delivery.

What Is Rockwool Blanket Insulation?
Rockwool blanket insulation is a flexible mineral wool product made from volcanic basalt rock and recycled materials. When manufactured at extremely high temperatures, it forms a dense, fibrous blanket that can be easily wrapped around pipes, vessels, ductwork, and other irregular surfaces.
Unlike rigid insulation boards, Rockwool blanket can be cut, shaped and fitted around complex equipment, making it a popular choice in industrial and commercial environments where standard insulation products may not be practical.
One of its biggest advantages is its passive fire protection. Rockwool is non-combustible, meaning it won’t contribute to the spread of fire, making it well-suited to high-temperature environments such as boiler rooms, kilns and steam systems. It also continues to perform well in damp conditions, helping maintain thermal efficiency in environments where moisture, condensation and water exposure are common.
Typical applications of Rockwool Blanket Insulation
Rockwool blankets are versatile, giving them many different applications across a number of industries.
Industrial Facilities
Rockwool blanket is a proven solution for industrial facility insulation, protecting workers from heat and noise exposure, improving energy efficiency, and reducing overhead costs. Its flexibility means it can be wrapped around large machinery, tanks, vessels, and irregularly shaped equipment across a wide range of industrial applications.
Commercial Infrastructure
For large-scale commercial builds, Rockwool blanket provides an intelligent insulation solution for expansive surface areas. Lightweight and easy to handle on site, it suits new construction and retrofit applications alike, from large mechanical rooms through to plant rooftops and building services.
Boilers, Heat Exchangers, Reactors
Consistent process temperature control is critical to efficient heat exchange in boilers and reactors. Rockwool blanket prevents heat loss from coils, mechanisms, and heated water or gas in transit, improving system efficiency, reducing energy consumption, and extending equipment life. It performs particularly well on large-diameter pipework and irregularly shaped process components that are difficult to insulate with prefabricated sections.
Mechanical Plants
Rockwool blanket delivers thermal and acoustic insulation for mechanical plant environments. Its flexibility makes it far more practical than rigid board formats for wrapping larger process equipment regardless of shape, and it can be customised with wire mesh and metal bands to suit large-diameter pipework, small vessels, and equipment near kilns, autoclaves, and boilers.
Steam Lines
Pressurised steam lines are inefficient and dangerous without sufficient insulation. Rockwool blanket maintains internal temperature and pressure while its non-combustible composition protects personnel from contact with hot pipe surfaces. Thermal insulation performance is also maintained when in contact with water, making it a reliable choice across steam and high-temperature fluid applications.
Manufacturing Facilities
In active manufacturing environments, Rockwool blanket insulation reduces ambient noise levels, manages heat exposure for workers, and improves the thermal performance of plant equipment and infrastructure — contributing to both energy savings and a safer, more comfortable working environment.
Benefits of Rockwool Blankets
The benefits of Rockwool blankets are extensive, and they can be used in a variety of settings. Some of these benefits include the following:
Flexible & Suited for Large Surfaces
Available in 100mm to 1200mm widths, our medium-density Rockwool blanket can be cut to fit large and small cavities and surfaces alike. It installs easily on boilers, heat exchangers, reactors, and larger process equipment, with flexible fixation options making it simple and quick to apply across even the most difficult surface areas.
Cost Savings
The fire and thermal properties of Rockwool blanket reduce energy consumption across both buildings and machinery, cutting heating costs and lowering electricity demand. Personnel protection and accident prevention also reduce costs associated with potential damage and compensation claims.
Non-Combustible Fire Resistance
Rockwool blanket is non-combustible and will not ignite or contribute to fire spread, making it a safe and compliant choice for high-risk environments, including boiler rooms, steam systems, kilns, and autoclaves, where fire safety is critical.
PPE & Safety
Rockwool blankets and Rockwool pipe sections protect personnel by insulating exposed hot surfaces in industrial and commercial facilities. Rockwool blanket also limits condensation, preventing moisture build-up that can cause infrastructure damage and hazardous mould growth.
Energy Efficiency
Rockwool blanket insulation keeps heat and sound in and cold and noise out across plants, warehouses, and commercial buildings year-round. The result is lower energy costs, improved environmental compliance, and a safer, more comfortable workplace.

Frequently asked questions
Rockwool blanket is a flexible, cut-to-fit product suited to irregular surfaces, large equipment, and custom applications. Rockwool pipe insulation sections are prefabricated units designed for standard pipe sizes and offer a faster, ready-to-install solution for straight pipe runs. Many projects use both. Our team can advise which is right for your application.
Yes. Rockwool blanket complies with AS/NZS 4859.1 for thermal insulation materials used in buildings, meets non-combustibility requirements under AS 1530.1, and satisfies AS 1530.3 for spread of flame and smoke development. It is also recognised by Safe Work Australia as a low-bio-persistent material, meaning it is fully classified as safe to use within Australian hazardous substance guidelines.
We offer same-day or next-day delivery across Queensland and Northern NSW. If you have an urgent requirement, call us directly on 1300 180 926 and we’ll do everything we can to meet your deadline.
Both. We supply single orders for specific project needs as well as ongoing supply arrangements for contractors and businesses with regular insulation requirements. Get in touch to discuss what works best for your situation.
Rockwool blanket can be secured using wire mesh, metal banding, or mechanical fixings, depending on the surface and application. This makes it suitable for everything from flat wall surfaces through to large-diameter pipework and irregularly shaped vessels.
