1. Excellent thermal insulation performance: Due to its fibrous structure, rock wool can effectively isolate thermal energy and adsorb air to reduce heat transfer. 2. Moisture and steam resistant layer: The aluminum foil surface layer plays a waterproof and moisture-proof role, which can prevent rock wool from absorbing water. This is particularly important in humid environments or in situations where condensation water may exist (such as in humid environments or in applications where rock wool is used in humid environments), as it helps maintain the insulation performance of rock wool and prevent mold growth. 3. Fire resistance: Rock wool itself is non flammable and will not melt or release toxic smoke at temperatures up to about 1000 ° C. Adding equally non flammable aluminum foil will enhance its fire resistance, making it an ideal material for fire protection applications. 4. Sound insulation effect: The dense and fibrous structure of rock wool has excellent sound insulation effect, which can effectively reduce noise transmission between different spaces. Aluminum foil does not affect this characteristic and can even serve as an additional sound barrier, providing auxiliary sound insulation. 5. Reflective surface: Aluminum foil can reflect radiant heat, thereby further enhancing the thermal performance of insulation materials. This is particularly useful in application scenarios where radiation heat issues are prominent, such as in attic spaces, around pipelines or high-temperature equipment. 6. Easy installation: The rock wool insulation material wrapped in aluminum foil is easy to operate and install. It can be cut into various shapes and sizes, and is usually supplied in the form of rolls, boards, or strip insulation cotton to meet different application needs.
