Rockwool Blankets (Rolls)

Description

ROCKAL Duct Warp is a type of flexible insulation made from spun mineral wool, which is derived from a mixture of volcanic rock and slag.

Fibers are bonded together with a thermosetting binder which gives the flexibility & resilience to the products. Rockal Rockwool Rolls are high performance solution for thermal & acoustic insulation for a range of commercial and industrial Buildings.

They are durable, easy to handle, cut and install. ROCKAL Rockwool Rolls comply with ASTM C-553-92 Type VII, E-84, E-119.

Application

• Thermal & Acoustic insulation of rectangular and round, heating, ventilation, air conditioning duct work temperature range 10°C to 600°C.
• Used in commercial, industrial, and residential buildings specially for small areas. Helps saving energy up to 80%, controlling heat loss or gain and condensation during system operations.
• Wall insulation - Rockwool blanket insulation can also be used in walls, either as a standalone insulation solution or as a supplement to existing insulation.
• HVAC systems - Rockwool blanket insulation is commonly used to insulate heating and cooling ducts, reducing heat loss and improving energy efficiency.
• Fireproofing - Rockwool blanket insulation can also be used for fireproofing in areas where fire safety is a concern.

Facing

ROCKAL Duct Wrap are faced with reflective vapor barrier material (Reinforced Aluminum Foil FSK).
FSK, FRK, Unfaced, Wire mesh, BGT, BGF, Kraft Paper, Vinyl Film.

Advantages

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

FIRE SAFETY

ROCKAL Rockwool 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, rockwool blanket insulation is a flexible and versatile 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.
