Performance Advantages of our VIG

LandVac is 100% fully tempered vacuum insulated glass.

Fully Tempered

Surface stress and granularity meet tempered glass standards and passed several key safety tests including wind resistance test and impact test. Each piece of 8.3 mm thick LandVac can withstand the pressure of a 1.7 m tall sand column, equivalent to 1 m2 of LandVac having 20 adults with an average body weight of 70 kg standing on the surface. By adopting low temperature sealing technology, LandVac completely retains the high strength, impact resistance, and other safety attributes of tempered glass. In case the glass breaks, it shatters into small and less harmful honeycomb shaped particles.

Thermal Insulation

U-value as low as 0.4 W/(m2·K). A 8.3 mm thick LandVac has better thermal insulation effect than the 1.5 m thick brick wall. Thanks to the high vacuum chamber of LandVac, which effectively blocks the thermal transmission, the thermal insulation performance of LandVac is 2-4 times better than insulated glass and 6-10 times better than single pane glass. The properties of this product meet all international thermal transmittance requirements on windows and doors for passive houses.

Noise Reduction

With its weighted sound reduction index exceeding 36 dB, LandVac makes rooms in downtown quiet like a library. 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.
