Abstract
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.
