There are several types of insulation available for aluminum profiles, including thermal insulation, acoustic insulation, and electrical insulation. Thermal insulation materials such as polyurethane foam or mineral wool can be used to prevent heat transfer. Acoustic insulation, like soundproofing panels or rubber seals, can reduce noise transmission. Electrical insulation is crucial for preventing electrical conductivity and can be achieved with materials like neoprene or silicone rubber. Each type serves a specific purpose and is chosen based on the application's requirements, such as temperature control, noise reduction, or electrical safety.
