Rockwool Insulation Products in South Africa (Rockfibre Range)
Rockwool insulation, also known as Rockfibre, is a high-performance stone wool insulation used in applications where fire resistance, acoustic performance, and durability are critical. Made from natural rock fibres, this type of insulation is widely used in residential, commercial, and industrial environments.
Rockwool insulation is known for its non-combustible properties, high density, and long-term stability, making it suitable for demanding insulation systems where standard materials are not sufficient.
What is Rockfibre (Rockwool) Insulation?
Rockfibre insulation is a type of stone wool insulation, commonly referred to as rockwool insulation. It forms part of the broader mineral wool category but is specifically designed for high-performance applications.

Rockwool insulation is manufactured from natural rock materials that are spun into dense fibres, creating a strong and stable insulation product that performs consistently over time.
Rockwool Insulation Prices in South Africa
Rockwool insulation prices in South Africa vary depending on board density, thickness, and product format. Higher density products cost more due to their improved fire resistance, acoustic performance, and mechanical strength.
Rockwool insulation prices depend on both density and thickness. Each density is available in multiple thicknesses — thicker boards within the same density provide higher thermal and acoustic performance and are priced accordingly. The price ranges below reflect the full thickness range available for each product.
Rockfibre Boards By Density
| Density | Price Range |
|---|---|
| 60kg/m³ | R1,017 – R1,594 |
| 80kg/m³ | R1,516 – R1,599 |
| 100kg/m³ | R2,020 – R2,158 |
| 120kg/m³ | R2,324 – R2,461 |

Key Benefits of Rockwool Insulation
Fire Resistance
Rockwool insulation is non-combustible and can withstand very high temperatures without burning. This makes it ideal for:
- Fire-rated wall systems
- Roof assemblies
- Industrial and commercial installations
- Partition systems
Acoustic Performance
Due to its density, rockwool insulation provides excellent sound absorption.
- Reduces airborne noise
- Ideal for offices, homes, and studios
- Suitable for soundproofing applications
Thermal Performance
Rockwool insulation delivers consistent thermal performance:
- Reduces heat transfer
- Helps maintain stable indoor temperatures
- Suitable for both hot and cold environments
Durability and Stability
Rockfibre insulation is designed for long-term performance:
- Does not sag or collapse
- Resistant to moisture and mould
- Maintains performance over time
Rockwool Insulation Applications
Rockfibre (rockwool) insulation is used in a wide range of applications:
- Wall insulation for cavities and partition systems
- Roof insulation for thermal and fire protection
- Ceiling insulation where higher density materials are required
- Soundproofing insulation for noise control
- Fire-rated insulation systems
