EPiC database - Glasswool insulation

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.Glasswool or fibreglass insulation contains micro fibres of glass that trap pockets of air within. This results in a low density and low thermal conductivity (0.04 W/(m·K)), which is ideal for insulation materials.Glasswool is made by mixing sand and recycled glass and melting them at 1 450°C to obtain glass. This glass is turned into fibres using a process similar to making cotton candy, by forcing it through a mesh and cooling it by contact with air. A binder is added beforehand to ensure cohesion and mechanical strength. The resulting fibre is heated at 200°C to polymerise the resin. The resulting insulation is calendered, before being cut and packed in rolls or panels.Glasswool insulation is widely used in the construction industry as an insulation material.

本材料收录于免费的环境性能建设数据库（Environmental Performance in Construction, 简称EPiC）。该数据库运用全面综合的混合生命周期清单方法，提供了250多种建筑材料的环境负荷流动系数。玻璃棉或玻璃纤维绝缘材料内含有微细的玻璃纤维，能够捕捉空气气泡，从而实现低密度和低热导率（0.04 W/(m·K)），这对于绝缘材料而言是理想的选择。玻璃棉的生产过程包括将沙子和回收的玻璃混合，并在1 450°C的温度下熔融以获得玻璃。随后，通过类似制作棉花糖的工艺，将玻璃熔融物通过网状结构并冷却至空气接触，从而转化为纤维。在生产过程中，预先添加的粘合剂确保了纤维的粘合性和机械强度。纤维在200°C的温度下加热以聚合树脂。最终制成的绝缘材料经过压延处理后，被切割并卷装或面板状包装。玻璃棉绝缘材料在建筑行业中作为绝缘材料得到了广泛应用。
