Aluminum foil mineral wool boards are a type of mineral wool board known for their excellent waterproofing and insulation properties. These boards are made by applying a layer of aluminum foil to the surface of the mineral wool base material. As an industrial manufacturing raw material, aluminum foil is primarily used in packaging protection, household goods, and construction. It ensures light-blocking, non-falling, light-proof, non-polluting characteristics, and is affordably priced. They are supplied for moisture-proof and decorative uses in premium cigarettes, candies, and insulation materials. The application of aluminum foil to the surface of the mineral wool board significantly enhances its waterproofing capabilities.

Waterproof and Insulation: Rock wool boards with added aluminum foil paper enhance waterproof properties and offer excellent insulation due to their low thermal conductivity. Good thermal insulation is a fundamental characteristic of rock wool and its products. Under normal temperature conditions (around 25℃), the thermal conductivity of rock wool typically ranges from 0.03 to 0.047 W/(m·K).
Fire Retardant: The surface material and insulation material of the mineral wool board are non-combustible, fully meeting fire safety standards. The flammability depends on the amount of combustible adhesive used. Mineral wool itself is an inorganic mineral fiber and is non-combustible.
Durability: Multiple studies, along with over 40 years of widespread use abroad, confirm that color-coated steel plates treated with special coatings have a service life of 10-15 years. Afterward, applying anti-corrosion coatings every 10 years can extend the lifespan of the sheets to over 35 years.
Aesthetics: Adaptable to complement any architectural style, achieving a satisfactory outcome.
Sound Insulation: Rock wool and slag wool products exhibit excellent sound insulation and absorption properties. The absorption mechanism lies in their porous structure, where, as sound waves pass through, friction is generated due to flow resistance, causing a portion of the sound energy to be absorbed by the fibers, thereby hindering the transmission of sound waves [1].
Application
1. Petrochemical Industry - Insulation and thermal preservation for equipment in the oil, power, and chemical sectors, as well as sound absorption and noise reduction.
2. Construction Industry - Insulation, thermal insulation, acoustic absorption, and noise reduction for partition walls, curtain walls, roofs, and enclosures.
3. Industrial sector - thermal insulation and fireproofing for industrial kilns, ovens, large-diameter storage tanks, and ships, as well as decorative and moisture-proof surfaces such as moisture-proof aluminum foil, black (white) glass fiber fabric reinforced with glass fiber felt.
