Product Overview: Rockwool Blanket With Aluminum Foil
Rockwool blanket with aluminum foil (also known as foil faced rock wool blanket or aluminum foil faced mineral wool blanket) represents a flexible insulation material composed of fine fibers spun from molten basalt rock and blast furnace slag, with aluminum foil laminated on one side.
Specifically, the aluminum foil facing creates a reflective vapor barrier that reduces radiant heat transfer and provides moisture resistance.
Consequently, this dual-layer structure delivers excellent thermal insulation, sound absorption, and fire protection for HVAC ducts, walls, roofs, and industrial equipment.
TARCO Industry produces its rockwool blanket with aluminum foil from high-quality basalt rock and blast furnace slag, melting these raw materials at temperatures exceeding 1500°C.
During production, we fiberize the molten rock using high-speed spinning wheels and apply a hydrophobic binder to create a water-repellent blanket.
Ultimately, the product is precision-cut and laminated with reinforced aluminum foil on one side, providing a reflective surface that enhances thermal performance and protects against moisture ingress.
Key Features & Benefits of Rockwool Blanket With Aluminum Foil
Furthermore, the aluminum foil facing provides a reflective vapor barrier that reduces radiant heat transfer and improves overall thermal efficiency.
Additionally, rockwool blanket offers exceptional fire resistance with a melting point exceeding 1000°C, ensuring the highest level of fire safety.
Moreover, the product achieves Euroclass A1 non-combustible fire classification per EN 13501-1, the highest possible fire rating.
Consequently, low thermal conductivity of 0.034–0.045 W/m·K effectively reduces heat loss and improves energy efficiency in buildings and industrial systems.
Therefore, the dense fiber structure delivers superior sound absorption with a noise reduction coefficient (NRC) of 0.75 to 1.05 depending on density and thickness.
In addition, the hydrophobic binder ensures water repellency greater than 98%, preventing moisture absorption and maintaining thermal performance over time.
Furthermore, the product is chemically inert, rot-proof, vermin-proof, and resistant to microbial growth for long service life.
Finally, the aluminum foil facing also acts as a reflective radiant barrier, reducing heat gain in summer and heat loss in winter.
