Fire Resistant Insulation

Effective fire resistant insulation is essential for protecting buildings and lives in the event of a fire. Our high-performance stone wool insulation offers excellent fireproof qualities, making it a trusted choice for fire rated constructions across South Africa.

Whether you’re working on commercial buildings, industrial facilities, or residential developments, our fire resistant insulation solutions provide reliable passive fire protection while also delivering thermal efficiency and acoustic performance.

Why Choose Fire Resistant Insulation?

Rockwool-based fire resistant insulation is non-combustible and can withstand extremely high temperatures without melting or releasing toxic smoke. This makes it one of the most effective materials for fireproof insulation in modern construction.

Key benefits include:

  • Non-combustible with strong fire performance
  • Maintains structural integrity at high temperatures
  • Suitable for fire rated walls, ceilings, and compartmentation systems
  • Provides additional thermal and acoustic benefits
  • Long-lasting and low maintenance

Common Applications

Fire resistant insulation is widely used in:

  • Fire rated walls, ceilings, and partitions
  • Commercial and office buildings
  • Industrial facilities and warehouses
  • Apartment buildings and residential complexes
  • Service shafts, risers, and ductwork
  • High-temperature industrial environments

Recommended Fire Resistant Insulation Products

We offer two main types of fire resistant insulation:

  • Rockfibre Boards – Ideal for walls, ceilings, and fire rated constructions in both commercial and residential buildings. Easy to install and available in multiple densities to meet different fire performance requirements.
  • Rockfibre Wired Mats – Best suited for industrial and high-temperature applications such as boilers, ducts, pipes, and process equipment where flexibility and mechanical strength are needed.

Both options deliver strong fireproof performance along with thermal and acoustic benefits.

Which Density Offers the Best Fire Resistance?

Higher density materials generally provide better fire performance. Here’s a quick guide:

  • 60kg Fire Rated Boards — Suitable for general fire rated applications in residential and light commercial buildings.
  • 80kg Fire Rated Boards— Good for improved fire resistance in commercial and office developments.
  • 100kg Fire Rated Boards— Strong all-round fire performance for commercial buildings and higher fire-rated applications.
  • 120kg Fire Rated Boards— Excellent for high-performance fireproof insulation in industrial and demanding environments.
  • 160kg Fire Rated Boards— Best suited for maximum fire resistance and high-temperature industrial applications.

For demanding high-temperature environments, Rockfibre Wired Mats in 100kg and above are recommended.
