ISO 9774:2004为标准编写者提供了为建筑应用中使用的标准选择隔热材料性能的指南。 这些指南并不旨在证明任何特定产品适用于任何特定应用。 本标准仅适用于预制隔热产品，即制造的垫子和板，包括可能存在的任何饰面或覆盖物，但基本特征也可适用于其他隔热产品，如系统或组件中的原位隔热产品。 本标准仅涵盖在正常气候条件下用于建筑物的隔热产品。它不包括建筑服务的隔热产品，例如管道和供暖，也不包括工业用途的隔热产品。 本标准中给出的特性不包括声学特性，尽管某些应用领域可能还需要这些特性。

ISO 9774:2004 gives guidelines to the standards writer in selecting thermal-insulation material properties for standards used in building applications. These guidelines are not intended to prove the suitability of any particular product for any given application. The standard applies only to prefabricated thermal-insulation products, i.e. manufactured mats and boards including any facings or coverings which may be present, although the basic characteristics may also be applied to other insulation products, e.g. in situ in systems or components, where appropriate. The standard covers only thermal-insulation products for use in buildings within normal climatic conditions. It does not cover insulation products for building services, e.g. plumbing and heating, nor insulation products for industrial use. Acoustic properties are not included in the properties given in the standard, although these may be additionally required for some fields of application.
