By using flexible edge sealing materials, LandVac overcomes the seal failure problem caused by fragile sealing materials especially in the environment with big temperature difference between the inner and outer glass surfaces. Moreover, with the assistance of built-in high efficiency getter material, it can sustain a high level of vacuum for a long time.

CTI testing concludes that the metal sealing material is lead-free, hazard-free, and food-grade safe.

Thanks to the high vacuum chamber of LandVac , which effectively blocks the sound transmission, the sound insulation performance is far better than insulated glass. It has remarkable acoustic properties against high penetrative medium and low frequency noises such as traffic and construction noises.

The surface stress and fragmentation test of LandVac conform with the standard of tempered glass with wind pressure resistance up to 7200Pa, fully meeting the requirements of the national standard.

In comparison with triple-pane insulated glass, LandVac has only a quarter of its thickness and weighs at least 10 kg less per square meter while managing a better U-value. The thin and lightweight structure of LandVac allows high-end refrigerators, fenestration hardware, and window frames to reduce their size, extend the service life, while reducing the costs on storage and logistics.
