    • A vacuum packaged conformable insulation assembly may be installed in a cavity before the vacuum in the insulation assembly is released. The insulation assembly includes a compressible batt of mineral fibers such as fibrous glass wool. During manufacture, the batt is encased in a gas-impervious envelope. The envelope is vacuum-sealed to retain the batt in a compressed state. The envelope may be provided with opening structures for selectively releasing the vacuum in the envelope. The envelope is sufficiently large to permit the batt contained therein to fully recover when the vacuum is released. According to a method of the present invention, the envelope is placed in a cavity to be insulated, and then the envelope is ruptured to allow the batt to expand to cause the insulation assembly to conform to the cavity.
    • 绝缘组件中的真空被释放之前,真空包装的适形绝缘组件可以安装在空腔中。 绝缘组件包括可压缩的矿物纤维絮垫,例如纤维状玻璃棉。 在制造过程中,絮垫被封装在不透气的信封中。 将信封真空密封以将絮垫保持在压缩状态。 外壳可以设置有用于选择性地释放外壳中的真空的开口结构。 当真空释放时,外壳足够大以允许其中包含的毛细管完全恢复。 根据本发明的方法,将外壳放置在要被绝缘的空腔中,然后将外壳破裂,以允许絮垫膨胀以使绝缘组件符合空腔。
