Product Details

ROCKWOOL ProRox SL (Slab) insulation is a rigid and semi-rigid board series. Its key highlight is excellent “mechanical stability,” making it ideal for applications requiring strength and a neat, professional installation.

Key Features of the ProRox SL Family

  • Mechanical Strength: The slabs feature high and uniform density, preventing easy compression and offering better load-bearing capacity than the Blanket series.
  • Acoustic Insulation: The high-density fiber structure provides excellent sound absorption and significantly reduces noise transmission.
  • High Temperature Stability: Capable of withstanding constant heat up to 850°C while maintaining its shape without warping or shrinking.
  • Water Repellency: Features water-repellent technology to reduce the risk of Corrosion Under Insulation (CUI).
  • Fire Safety: Non-combustible CLASS A1 material, enhancing safety for buildings and industrial plants.

ProRox SL

ROCKWOOL ProRox SL (Slab) focuses on “Rigid Board” insulation designed for high mechanical stability, ideal for applications requiring strength, compression resistance, and installation on flat surfaces.

 

ROCKWOOL ProRox SL Series: Rigid Stone Wool Slabs for Heavy Industrial Structures

ROCKWOOL ProRox SL is an internationally recognized range of rigid and semi-rigid stone wool slabs for use in oil refineries, power plants, and industrial facilities requiring precise temperature control and superior fire protection.

ProRox SL Highlights

  • Structural Integrity: The slabs are highly stable and do not collapse or lose shape under continuous heat.
  • Versatility: Available in various densities (60 – 160 kg/m3) to meet needs ranging from sound absorption to high-level heat resistance.
  • Ease of Installation: Easy to cut and fits securely onto insulation pins.

 

Standards for Mineral Wool Insulation

ROCKWOOL ProRox SL slab insulation is tested according to ASTM C612, the standard specification for mineral fiber block and board insulation. With extensive testing under ASTM C612, the ProRox SL series is widely trusted by contractors and project owners.

Applications by ROCKWOOL Density Model

Choosing the right density helps optimize your budget and performance:

  1. Low Density Models (60 kg/m³)
  • Model: SL 930 SA
  • Application: Suitable for general insulation without load-bearing requirements, such as lining engine room walls for sound absorption or in drywall cavities for thermal and acoustic insulation in offices.
  1. Medium Density Models (80 – 100 kg/m³)
  • Model: SL 950 SA / SL 960 SA
  • Application: The most widely used “Standard Models” in industrial work.
    • Used for lining Boiler and Oven walls with flat surfaces.
    • Used for firewalls.
    • Ideal for sound absorption in machinery with medium to high frequency noise.
  1. High Density Models (110 – 128 kg/m³)
  • Model: SL 978 SA / SL 970 SA
  • Application:
    • Used in areas requiring extra high Fire Protection.
    • Used in extreme temperature applications where high density helps reduce thermal conductivity more effectively.
    • Ideal for installation in high-vibration machinery areas, as the slabs grip insulation pins more securely.
  1. Ultra-High Density Models (160 kg/m³)
  • Model: SL 540 SA
  • Application:
    • Heavy Duty: Used where maximum strength is required, such as areas subject to maintenance traffic where technicians may step on the slabs (when installed with support).
    • Used in high-performance fire partitions.

 

ROCKWOOL Applications

  1. Industrial Furnace & Oven Walls: Especially high-density models (SL 970 / SL 540) which offer excellent radiant heat resistance.
  2. Fire-rated Partitions: Used as a core material to increase the Fire Rating for buildings or offshore platforms.
  3. Sound Insulation: Stone wool structures with 80-100 kg/m³ density provide the best NRC (Noise Reduction Coefficient) for reducing noise pollution.
  4. Large Flat Surfaces: Such as ship bulkheads or rectangular storage tanks.

 

Application Tips

  • Rigid Board Installation: Use Insulation Pins and Speed Clips to secure the slabs, using approximately 5-9 pins per square meter to prevent shifting.
  • Combining Models: On the same site, SL 930/950 can be used for general areas, while high-density SL 540 is used for direct heat contact or frequent maintenance points due to its superior compression resistance.
  • Joints: Install slabs as tightly as possible. For multi-layer applications, use staggered joints to eliminate thermal bridges.
