## glass wool or rock wool; Which thermal and audio insulation for your project is the final and optimized choice?\r\n\r\n\r\nChoosing the right thermal and audio insulation is one of the key decisions in optimizing energy consumption, increasing comfort and enhancing safety in various buildings and industries. Among the many options available in the market, glass wool and stone wool have a special place due to proven performance and high adaptability. This article examines the deep and comparative review of these two products to help you choose the smartest option for your specific needs by providing accurate technical information.\r\n\r\n\r\n\r\n### Glass Wool (Glass Wool): Ambassador of Insulation\r\nGlass wool, one of the oldest and most well -known fiber insulators, is a product that uses a clever composition of recycled glass (on average, is used to produce a glass wool roll of about 10 recycled glass bottles), silica sand, and special resins. The process of its production involves melting these materials at high temperatures and then converting the glass to a very delicate and flexible fiber through centrifugal force or high -speed air blowing. These fibers, which are short -lived, are randomly attached to each other, forming millions of static and microscopic air cavities in their structure, forming the main thermal and acoustic insulation mechanism. The air in itself is a weak thermal insulation, and its trap in this porous structure prevents heat transfer to conductors, convection and radiation. Glass wool is usually offered in rolls (often with coatings such as aluminum foil to increase thermal reflection and resistance to water vapor, or craft paper for ease of installation) or board panels with different density.\r\n\r\n### Rock Wool (Rock Wool / Mineral Wool): The Hero of Resistance and Performance\r\nRock wool, a member of the larger family of mineral wool, is a fiber insulation that is produced from volcanic rocks, especially basalt stone, with steel furnace slag (as additives). The process of producing this product begins with the melting of basalt stone and other additives in high temperatures, usually between 1400 and 1600 ° C. The resulting molten material, similar to the glass wool production process, is affected by centrifugal force or high -pressure air flow and is converted to very thin fibers with micronic diameter (usually between 3 and 7 microns). These mineral fibers, which make up more than 97 % of the final composition of the rock wool, create interconnected, yet stable, by adding a small amount of phenolic resin (as a stick) and special oils (to excrete water and dust reduction). This structure also brings the extra thermal and acoustic insulation by imprisoning the air between the fibers. Stone wool in a variety of shapes such as board (with different density), roll or quilt (often with foil or paper coating), blankets (with one or two ways
