| Abstract |
Vacuum insulation panels (VIP) provide superior thermal insulation but face challenges with performance degradation over time. Standardized
long-term performance evaluation methods differ by core material and require more than six months to complete, delaying quality verification.
To address this limitation, an integrated accelerated test method was developed for evaluating VIP long-term thermal performance. The
method applies test conditions of 80 degrees Celsius and 70 percent relative humidity (RH) to enable rapid quality verification. Experimental
results showed that 25-year thermal performance predictions for both fumed silica and glass wool VIP met ISO quality standards. Comparison
with existing evaluation methods confirmed a similar level of prediction accuracy. This accelerated method offers a faster verification system
adaptable to different evaluation needs. By reducing the evaluation period, it is expected to support broader adoption of VIP technology in
the construction sector. |
