Insulation materials are usually added to the exterior walls of general buildings. Which ones are you most familiar with? Actually, there are many types of insulation materials, each applied to different fields. Friends in the construction industry are surely familiar with glass wool, but do you know why it provides insulation and the principle behind it? Let's explore together today!
Glass wool is a type of glass fiber, produced using a unique centrifugal technology, and is a man-made inorganic fiber. Molten glass is fiberized to form a cotton-like material. It features good formability, low bulk density, low thermal conductivity, heat preservation and insulation, good sound absorption performance, corrosion resistance, and stable chemical properties.
The fibers inside centrifugal glass wool are fluffy and crisscrossed, with numerous tiny pores. It is a typical porous sound-absorbing material with good sound absorption characteristics. Centrifugal glass wool can be made into glass wool felt, glass wool boards, glass wool strips, etc., which can absorb a large amount of sound in the room, reduce reverberation time, and reduce indoor noise.
To improve its appearance, glass wool is often added with aluminum foil facing, fabrics, etc., allowing it to be used in more places. It can be applied to various buildings, including offices, businesses, residences, hotels, and conference venues, creating private, quiet, and comfortable spaces for users.
