Abstract: The performance experiment of exterior wall insulation system for vacuum insulation board was carried out, and a new type of external wall thermal insulation tensile bond strength special cutting device was invented.The results show that, vacuum insulation board with lower thermal conductivity has good physical and mechanical properties. Vacuum insulation board thin plastering exterior wall thermal insulation system has better security performance and durability, anti-wind pressure performance reaches to 6.3kPa, exterior wall of weathering test after experiment is good, which is no hollowing, spalling and cracking, and tensile bond strength of finishing layer and the insulation layer reaches 0.08MPa after weathering test, system shock resistance reaches 3J. The system has a low water absorption and high water vapor density, and the external thermal insulation system of vacuum insulation panels has been used in some external wall and roofing projects, the effect is better.
