Rock wool Boards (Slabs)

Description

Rock wool board insulation is a type of rigid insulation made from spun mineral wool, which is derived from a mixture of volcanic rock and slag.

It is known for its high thermal resistance, soundproofing capabilities, and fire-resistant properties, making it a popular choice for insulation in a wide range of applications.

ROCKAL Boards are especially rigid than other ROCKAL Rock wool products and comply with ASTM C-612.

APPLICATION

• Wall insulation - Used to insulate both residential and commercial buildings, rock wool board insulation provides a continuous layer of insulation in walls, improving the overall energy efficiency of the building.
• Roof insulation - It is used to insulate roofs, including pitched and flat roofs, to prevent heat loss and reduce energy costs.
• Floor insulation - Rockal Rock wool board insulation is also used to insulate floor systems, particularly in commercial buildings where soundproofing is important.
• HVAC systems - Rockal Rock wool board insulation is commonly used to insulate heating and cooling ducts, reducing heat loss and improving energy efficiency.

Facing

ROCKAL Rock wool Boards can be non-Faced or faced with reflective vapor barrier material (Reinforced Aluminum Foil FSK) or Kraft Paper, fiber glass tissue BGT or BGF.

Advantages

• Fire resistance - Rockal Rock wool board insulation has excellent fire resistance, making it an ideal choice for areas where fire safety is a concern.
• Soundproofing - Rockal Rock wool board insulation provides excellent soundproofing properties, making it a great choice for noisy areas like theaters, recording studios, and multi-unit dwellings.
• Durability - Rockal Rock wool board insulation is long-lasting, durable and does not deteriorate over time, making it a cost-effective solution for insulation.
• Moisture and mold resistance -Rockal Rock wool board insulation is resistant to moisture and mold growth, making it a suitable choice for areas with high humidity or damp conditions.
• Environmentally friendly - Rockal Rock wool board insulation is made from sustainable and renewable materials and can be recycled, making it an environmentally friendly choice.
• Easy installation - Rockal Rock wool board insulation is easy to install, making it a popular choice for both contractors and DIY enthusiasts.

FIRE SAFETY

ROCKAL Rock wool fibers products are classified as Non-Combustible materials and follow the fire safety rating achievements:

• Class 1 Surface spread of flame in accordance to BS 476
• Class 0 in accordance to BS 476
• Class A1 in accordance to European standards
• Surface burning characteristics in accordance to ASTM E-84
• Fire Spread Index: Less than 10
• Smoke Developed Index: Less than 25

In summary, rock wool board insulation is a versatile and durable insulation solution that offers excellent fire resistance, soundproofing properties, and resistance to moisture and mold. It is an energy-efficient and environmentally friendly option for a wide range of insulation applications.
