Buy good quality low price Aluminium Foil Coated Rock Wool Blanket, Boards, Slab for application 650 Degree temperature at Wedge India. Aluminum foil-covered rock wool insulation is a high-performance insulation material that combines the thermal and acoustic insulation properties of rock wool with the additional benefits of an aluminum foil facing. This type of insulation is commonly used in construction, industrial, and HVAC applications where thermal insulation, moisture control, and fire resistance are critical.
 
Key Features and Benefits
1. Excellent Thermal Insulation:
• Rock wool, also known as mineral wool or stone wool, is made from volcanic rock and other natural minerals. It provides excellent thermal insulation due to its fibrous structure, which traps air and reduces heat transfer.
2. Moisture and Vapor Barrier:
• The aluminum foil facing acts as a barrier against moisture and vapor, preventing the rock wool from absorbing moisture. This is especially important in humid environments or applications where condensation might occur, as it helps maintain the insulation’s effectiveness and prevents mold growth.
3. Fire Resistance:
• Rock wool is inherently non-combustible, withstanding temperatures up to around 1,000°C (1,832°F) without melting or emitting toxic fumes. The addition of aluminum foil, which is also non-combustible, enhances the fire-resistant properties, making it ideal for fire protection applications.
4. Sound Insulation:
• The dense, fibrous structure of rock wool provides excellent acoustic insulation, reducing noise transmission between spaces. The aluminum foil does not interfere with this property and can even help by adding an additional sound barrier.
5. Durability and Mechanical Strength:
• Rock wool insulation is durable and resistant to compression, maintaining its shape and insulating properties over time. The aluminum foil facing adds an extra layer of protection against physical damage, making it suitable for use in exposed or high-traffic areas.
6. Reflective Surface:
• The aluminum foil reflects radiant heat, further enhancing the insulation’s thermal performance. This is particularly useful in applications where radiant heat is a significant concern, such as in attics, ducts, or around high-temperature equipment.
7. Ease of Installation:
• Aluminum foil-covered rock wool insulation is easy to handle and install. It can be cut to fit various shapes and sizes and is often available in rolls, sheets, or batts for different applications.
 
Common Applications
1. Building Insulation:
• Used in walls, roofs, ceilings, and floors to provide thermal and acoustic insulation in residential, commercial, and industrial buildings. The aluminum foil facing helps with moisture control and enhances the insulation’s thermal performance.
2. HVAC Duct Insulation:
• Wrapped around HVAC ducts to prevent heat loss or gain, control condensation, and reduce noise transmission through ductwork. The aluminum foil also acts as a vapor barrier, protecting the duct insulation from moisture.
3. Industrial Insulation:
• Applied to pipes, tanks, boilers, and other industrial equipment to reduce heat loss, protect against fire, and prevent condensation. The aluminum foil provides additional protection against physical damage and chemical exposure.
4. Attic and Roof Insulation:
• Installed in attics and under roofs to reflect radiant heat and improve overall energy efficiency in buildings. The aluminum foil helps keep spaces cooler in summer and warmer in winter.
5. Fire Protection:
• Used in fire-rated assemblies, such as fire doors, firewalls, and fireproof enclosures, where both thermal insulation and fire resistance are required.
6. Soundproofing:
• Employed in partition walls, floors, and ceilings to reduce noise transmission between rooms or between different areas of a building. The rock wool’s acoustic properties are enhanced by the aluminum foil barrier.
 
Specifications
1. Thermal Conductivity:
• Rock wool typically has a thermal conductivity ranging from 0.035 to 0.045 W/m·K, making it an efficient insulator for both heat retention and heat exclusion.
2. Density:
• The density of rock wool insulation can vary depending on the application, generally ranging from 40 to 200 kg/m³ (2.5 to 12.5 lb/ft³). Higher densities provide better acoustic and thermal insulation.
3. Thickness:
• Available in various thicknesses, typically ranging from 25 mm (1 inch) to 200 mm (8 inches), depending on the required insulation performance and application.
4. Fire Resistance:
• Rock wool is non-combustible, with a melting point above 1,000°C (1,832°F). The aluminum foil also has high fire resistance, contributing to the overall fire performance of the insulation.
5. Water Vapor Transmission:
• The aluminum foil facing provides a low water vapor transmission rate, acting as an effective vapor barrier to protect the rock wool from moisture ingress.
6. Sound Absorption Coefficient:
• Rock wool insulation typically has a high sound absorption coefficient, often exceeding 0.9 across a broad range of frequencies, making it highly effective for soundproofing.
 
Installation Considerations
• Cutting and Fitting: Aluminum foil-covered rock wool insulation can be easily cut to size using a utility knife or insulation saw. It should be cut slightly larger than the space it will fill to ensure a snug fit.
• Securing: The insulation can be secured in place using mechanical fasteners, adhesive, or by fitting it between studs, joists, or other structural members. The aluminum foil facing should be installed facing outward or toward the source of radiant heat for maximum effectiveness.
• Sealing Joints: When installing multiple pieces of insulation, it’s important to seal joints with high-temperature tape or adhesive to prevent air leaks and maintain the integrity of the insulation.
 
Aluminum foil-covered rock wool insulation is a versatile, high-performance material that offers excellent thermal insulation, soundproofing, fire resistance, and moisture control. Its wide range of applications makes it suitable for use in building construction, HVAC systems, industrial processes, and fire protection. The combination of rock wool’s insulating properties with the reflective and protective benefits of aluminum foil makes this material an effective solution for a variety of insulation challenges.
