Description

Rockwool Duct Board is a high-quality, rigid insulation board designed specifically for HVAC ducts. It is made from natural molten basalt rocks spun into fine fibers, bonded with a heat-resistant binder, and faced with a reflective, water-retardant aluminum foil. This composition provides exceptional thermal and acoustic properties, contributing to significant energy savings and a quieter environment. The product is non-combustible, with a Flame Spread Index of 0 and a Smoke Developed rating of 0, ensuring the highest level of fire safety for your building’s HVAC system. Its robust nature also makes it noncorrosive and resistant to fungi growth, ensuring long-term durability.

The Duct Board offers a wide range of performance with a thermal conductivity from 0.038 to 0.034 W/m.K and a high Noise Reduction Coefficient (NRC) of 0.65 to 1.0, effectively insulating against both heat and sound. Gitco-sa.com provides a complete range of these products, with variations in thickness from 25 mm to 100 mm and densities from 35 kg/m³ to 160 kg/m³ to suit diverse project requirements. It is available with different facings, including none, Aluminum Foil FSK, or O class, giving you tailored options for specific applications.

Key Applications of Rockwool Duct Board:

• HVAC Duct Insulation: The primary application for both supply and return air ducts, whether concealed or exposed.
• Fire Safety Barriers: Provides up to 2 hours of fire resistance integrity, protecting ducts in fire-rated assemblies.
• Acoustic Barriers: Reduce fan noise and airflow sounds transmitted through ductwork.
• Industrial Insulation: Suitable for insulating vessels and tanks within industrial settings due to its high maximum use temperature of 650°C.

Know more about Rockwool Duct Board:

1. What is Rockwool Duct Board?
   It’s a semi-rigid to rigid insulation board made from basalt rock fibers, bonded with a thermosetting resin. It’s specifically engineered for insulating square and rectangular HVAC ducts.
2. How is it different from Rockwool Duct Wrap?
   Duct board is a rigid panel, best suited for flat, large duct surfaces. Duct wrap is a flexible roll, ideal for wrapping circular ducts or those with irregular shapes.
3. What are its primary functions?
   It serves three main purposes: thermal insulation to maintain air temperature, acoustic insulation to reduce noise, and fire protection to prevent flame spread.
4. How does it improve thermal performance?
   Its fibrous composition creates tiny air pockets that act as a barrier to heat transfer, significantly reducing heat loss or gain from the duct. This makes HVAC systems more energy-efficient.
5. What is its thermal conductivity (k-value)?
   The thermal conductivity is typically low, around 0.034 W/mK, which indicates its high efficiency in preventing heat flow.
6. Does it have a good fire rating?
   Yes, rock wool is inherently non-combustible. Duct board products are rated Euroclass A1, the highest fire safety classification, and have a melting point exceeding 1000°C.
7. Is it a good soundproofing material?
   Yes, its dense, fibrous structure is excellent for sound absorption and helps dampen noise from air turbulence and vibrations in the ductwork.
8. What types of ducts is it best for?
   It is specifically designed for use on rectangular and square ducts due to its rigid, board-like shape.
9. Does it prevent condensation?
   Yes, it is often supplied with a factory-applied vapor barrier (like a reinforced aluminum foil) on one or both sides to prevent moisture from reaching the cold duct surface and causing condensation.
10. Is it resistant to moisture and mold?
    Yes, the rock wool fibers are naturally hydrophobic and repel water, which prevents moisture absorption and inhibits the growth of mold, fungi, and bacteria.
11. How is it installed?
    The rigid boards are cut to size and mounted onto the duct surface using mechanical fasteners (insulation pins). The joints and seams are then sealed with self-adhesive aluminum foil tape to ensure a continuous vapor barrier.
12. Is it suitable for high-temperature applications?
    Yes, with a maximum service temperature of up to 230°C, it is well-suited for both chilled and hot air ducts.
13. What are its standard dimensions?
    Common sizes are typically 1.2m x 0.6m with a range of thicknesses from 25 mm to 100 mm.
14. What is the typical density of the board?
    The density is usually in the range of 35 to 50 kg/m³, balancing acoustic and thermal performance with ease of handling.
15. Does it contain harmful substances like asbestos?
    No, high-quality rock wool duct board is asbestos-free and does not contain CFCs or HCFCs, making it an environmentally friendly choice.
16. How does it contribute to green building certifications?
    By reducing energy consumption and being made from a natural, abundant resource, it can contribute to credits for certifications like LEED (Leadership in Energy and Environmental Design).
17. Is it durable and long-lasting?
    Yes, its rigid structure ensures it is dimensionally stable and will not sag, settle, or degrade over time, maintaining its performance for the life of the building.
18. Can it be used on outdoor ducts?
    Yes, when combined with a durable, weatherproof facing or cladding, it is suitable for insulating external ductwork.
19. What international standards does it comply with?
    Rockwool Duct Board, for example, is manufactured to comply with international standards such as ASTM C-612, ensuring its quality and performance.
20. Where can one purchase Rockwool Duct Board in the Middle East?
    A specialized supplier like Gitco-sa.com, which partners with leading brands, would be a primary source for this product in the UAE and Saudi Arabia.
