Aluminum foil rock wool board is a type of insulation material with excellent waterproof properties. It is made by applying a layer of aluminum foil to the surface of rock wool board. As an industrial manufacturing raw material, aluminum foil is primarily used for packaging protection, household items, and construction. It ensures light-blocking, non-falling, light-proof, non-polluting, and affordable pricing. It is supplied for moisture-proof and decorative uses in premium cigarettes, candies, and insulation materials. The application of aluminum foil to the rock wool board significantly enhances its waterproof capabilities.

Waterproof and Insulation: Rock wool boards with added aluminum foil paper enhance waterproof performance and offer excellent thermal insulation due to their low thermal conductivity. Good thermal insulation properties are a fundamental characteristic of rock wool and its products, with a thermal conductivity typically ranging between 0.03～0.047 W/(m·K) under normal temperature conditions (around 25℃).

Fire Retardant: The surface material and thermal insulation of mineral wool board are non-combustible, fully meeting fire safety specifications. The combustion performance depends on the amount of flammable binder used. Mineral wool itself is an inorganic mineral fiber that is non-combustible.

Durability: Multiple studies and over 40 years of widespread use internationally confirm that color steel plates treated with a special coating have a lifespan of 10-15 years. Afterward, by applying anti-corrosion coatings every 10 years, the lifespan of the plates can extend to over 35 years.

Aesthetics: Can be matched with the requirements of any architectural style to achieve satisfactory results.

Sound Insulation: Rock wool and slag wool products exhibit excellent sound insulation and absorption properties. The absorption mechanism lies in the porous structure of these products; 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 impeding the transmission of sound waves [1].

Application

1. Petrochemical Industry – Insulation and thermal preservation for equipment in the oil, power, and chemical sectors; sound absorption and noise reduction.

2. Construction Industry — Insulation, thermal insulation, sound-absorbing, and noise-reducing materials for partition walls, curtain walls, roofs, and enclosures.

3. Industrial sectors - Industrial kilns, ovens, large-diameter storage tanks, and ship insulation for fire prevention, etc., can also be decorated with moisture-proof aluminum foil, black (white) glass fiber fabric reinforced with glass fiber felt, and moisture-proof facing materials applied to the surface of rock wool boards.
