The technical specifications of glass wool boards are primarily defined by key parameters such as density, thermal conductivity, fire resistance, sound absorption coefficient, and dimensions; these specifications vary depending on the intended application.
Regarding thermal insulation, thermal conductivity is a critical indicator, typically ranging from 0.032 to 0.045 W/(m·K); a lower value signifies superior insulation performance. Density generally falls within the 10–100 kg/m³ range, with different densities suiting different strength requirements and application scenarios-for instance, lower densities are better suited for sound absorption, while higher densities are ideal for thermal insulation and structural filling.
Glass wool boards are non-combustible materials, typically meeting the Class A1 non-combustibility standard; they do not produce open flames or release toxic fumes under high-temperature conditions, making them widely used in building fire protection systems. Additionally, they possess a melting point generally exceeding 600°C, demonstrating excellent high-temperature stability.
The sound absorption coefficient typically ranges from 0.7 to 1.0 (depending on thickness and density), offering effective absorption of medium- to high-frequency noise. In terms of dimensions, common thicknesses include 25mm, 50mm, 75mm, and 100mm, while lengths and widths are customized to project requirements-with 1200mm × 600mm being a common size. In practice, these parameters are selected and combined based on design specifications to meet the performance needs of specific projects.
