1. Flexible Lead-free Ti-Alloy Sentry
Vacuum Insulated Glass uses titanium alloy with excellent plasticity and toughness for edge sealing, which minimizes additional stress from welding and significantly enhances the vacuum insulated glass's bending strength and wind pressure resistance. Additionally, titanium's high specific strength, low thermal conductivity, and high gettering properties further improve the overall performance of LandVac's supports and getters. This ensures the structural strength and longevity of the vacuum insulated glass.
2. Continuous Vacuumizing Process
According to gas desorption rules, a reasonable exhaust temperature and negative pressure exhaust process are set along a vacuum line of over 40 meters. After 2 hours of thorough exhaust, online vacuum detection, and offline measurement and calculation, the vacuum level of each qualified product is ensured.
3. Multiple Safety Enhancement
LandVac uses the tempered safety glass as its sheet glass sealed with FLAS Flexible Lead-free Ti-Alloy Sentry in the process. The stress balance control technology after sealing completely eliminates the additional stress on the edge of LandVac, allowing LandVac to have its bend strength, wind pressure resistance, and comprehensive safety far superior than those of similar products.

Q: What is the difference between heat preservation and insulation?
A: Heat preservation and insulation are two concepts. Insulation performance indicates the ability to prevent heat transfer from the indoor high temperature to the outdoor low temperature side in winter, mainly through the vacuum between the glass and the hollow layer. Thermal insulation performance indicates the ability to block solar radiation heat in the summer, mainly through the configuration of Low-E coated glass to achieve. Therefore, when selecting glass, it is necessary to take into account two performance indicators of thermal insulation and thermal insulation, that is, the solar heat gain coefficient g value and the heat transfer coefficient U value.
Note: g value: (solar heat gain coefficient), the smaller the value, the better the heat insulation performance in summer.
U value: (thermal conductivity coefficient), the unit is W/m2·K, the lower the U value, the better the insulation performance.
