Defects in the Envelope Barrier of Vacuum Insulation Panels after Hygrothermal Aging in Severe Conditions

摘要：

　　The use of VIPs for building application is limited by the degradation of the barrier performance of the envelope,especially at high temperature and humidity.The most critical component of a VIP is the envelope.It is responsible for preventing permeation in the core material.This multilayered materials is however sensitive to degradation.The effect of hydrothermal ageing was investigated thoroughly,leading to the identification of series of possible defects.In this paper,the flaws are presented and plausible explanations for their origin were given.
