摘要:
A vacuum insulation panel comprises a barrier film and a core material and a vacuum detection indicator. The vacuum detection indicator is configured to facilitate the evaluation of the integrity of the vacuum within the vacuum insulation panel. The vacuum detection indicator may comprise a cavity in the core material which allows the barrier material to form a depression when a vacuum is drawn within the panel. Accordingly, as the vacuum is reduced or lost, the depression formed in the barrier material will be similarly reduced or lost. In addition, the vacuum detection indicator may comprise a viewing window configured above the barrier material to permit the evaluator to readily determine whether the vacuum has been reduced or lost. Further, the vacuum detection indicator may comprise a spring-like device configured within the cavity.
