按照国家《建筑外墙保温材料技术规范》（GB50245-2010）的要求，我国的建筑外墙保温材料必须进行更新。在这方面，各地均已采取了一系列措施，以提高建筑外墙保温材料的性能和使用寿命。 首先，对建筑外墙保温材料的质量进行严格把关，使其符合国家规定的标准。其次，政府要求建筑外墙保温材料必须采用新型环保材料，如聚氨酯、聚苯乙烯等，以提高建筑外墙保温材料的热阻性能和耐久性。此外，政府还鼓励建筑外墙保温材料的制造商投资研发新型材料，以及新型施工方法，以提高建筑外墙保温材料的使用效果。 上述措施的实施，有助于提高建筑外墙保温材料的质量和使用寿命，为我国建筑行业的发展做出了贡献。 Update on External Wall Insulation Materials In accordance with the national technical specification for external wall insulation materials (GB50245-2010), the external wall insulation materials in China must be updated. In this regard, a series of measures have been taken in various places to improve the performance and service life of external wall insulation materials. First of all, strict control over the quality of external wall insulation materials is required to meet the national standards. Secondly, the government requires that new environmental protection materials such as polyurethane and polystyrene must be used for external wall insulation materials to improve their thermal resistance and durability. In addition, the government also encourages manufacturers of external wall insulation materials to invest in the research and development of new materials and new construction methods to improve the performance of external wall insulation materials. The implementation of these measures helps to improve the quality and service life of external wall insulation materials, and makes a contribution to the develo |
