Stone Wool

Stone Wool Insulation
Stone wool insulation is a high-density mineral insulation material manufactured from volcanic rock such as basalt. It is designed for applications where fire resistance, acoustic control, mechanical strength, and temperature stability are critical.
Stone wool insulation products like Rockfibre are supplied by Insulation Warehouse are commonly specified for commercial, industrial, fire-rated, and acoustic insulation systems where performance and safety requirements are higher than standard building insulation.
What Makes Stone Wool Different
Stone wool differs from lightweight insulation materials due to its rigid structure and higher density, allowing it to maintain performance under extreme conditions such as high temperatures and exposed installations.
Key characteristics of stone wool insulation include:
- Non-combustible material with high fire resistance
- Excellent acoustic absorption due to dense fibre structure
- Stable thermal performance across a wide temperature range
- High mechanical strength for rigid board applications
- Resistance to moisture and long-term dimensional stability
Common Applications of Stone Wool Insulation
Stone wool insulation is typically used in environments where safety, durability, and performance are essential.
Fire-Rated Insulation Systems
Stone wool is widely used in fire-rated walls, ceilings, ducts, and service penetrations due to its non-combustible properties.
Industrial Insulation
High-density stone wool products are used for insulating industrial equipment such as boilers, vessels, tanks, and pipe systems where temperature resistance is required.
Acoustic and Soundproofing Applications
The dense fibre structure of stone wool makes it effective for noise control in plant rooms, studios, commercial buildings, and industrial facilities.
Commercial and High-Performance Buildings
Stone wool is often specified in commercial projects where higher performance standards apply compared to residential insulation systems.
Stone Wool Product Types
Stone wool insulation is available in different product formats to suit specific applications:
- Rigid stone wool boards – used for flat surfaces, fire-rated systems, and industrial insulation
- Stone wool wired mats – flexible insulation for pipes, vessels, and curved industrial equipment
Stone Wool vs Glasswool Insulation
While both materials fall under the mineral wool category, they serve different purposes.
- Stone wool insulation is selected where fire resistance, rigidity, acoustic performance, or high-temperature stability is required.
- Glasswool insulation is typically used for lightweight thermal and acoustic insulation in residential and commercial building applications.
For lightweight building insulation, view our glasswool insulation range.
