Application of Vacuum Insulated Glass in Construction Field

With the introduction of green building-related national policies, building energy efficiency has received more and more attention. Research data show that building energy consumption has accounted for one-third of the total energy consumption of society. While 50% of the building energy consumption is lost through windows and doors, 80% of the loss can be attributed to glass. In the meantime, the wastewater, gas, and residue produced by energy production impose great risk to the construction of the ecological civilization and human health. Under such a severe situation, it is imperative to speed up the development of green energy-saving building materials such as vacuum insulated glass.

By definition, vacuum insulated glass is an item consisting of two or more panes of sealed up glass with the air in the tiny space between the panes removed to achieve a vacuum state. As a new high-performance energy-saving glass product with a remarkable energy-saving effect, vacuum insulated glass has the advantages of low heat transfer coefficient, high sound insulation performance, and light structure. It is an ideal energy-efficient and environmentally friendly material, capable of significantly improving the performance indicators such as building energy-saving standards and indoor environment to raise the overall building quality. A team of one hundred R&D researchers from LandGlass launched the tempered vacuum insulated glass LandVac® after eight years of endeavor. It offers seven major advantages, including superior thermal and sound insulation performance, especially when compared with ordinary vacuum glass.

Energy-saving green product

Thanks to the high vacuum chamber of LandVac that effectively blocks the thermal transmission, the thermal insulation performance of LandVac is 2-4 times better than laminated glass and 6-10 times than single pane glass. The properties of this product meet all international thermal transmittance requirements on windows and doors for passive houses. In addition to significantly reducing the energy consumption in the construction sector and the emission of wastewater, waste gas, and waste residue, it can mitigate certain “A/C diseases” symptoms associated with staying in an air-conditioned environment for an extended period of time such as dizziness and upper respiratory tract infection.

Effective noise reduction

Thanks to the high vacuum chamber of LandVac that effectively blocks the sound transmission, the sound isolation performance is far better than the laminated glass. It has a remarkable soundproof effect against high penetrative mid-low frequency noises such as traffic and construction noises. With the increasing density of urban buildings, traffic flow, and shopping malls, noise has become one of the most severe pollution sources. The emergence of LandVac has a far-reaching significance for restoring a peaceful and harmonious living environment.

High safety

Surface stress and granularity of LandVac meet tempered glass standards. It has passed several key safety tests including the wind resistance test and impact test. Each piece of LandVac can withstand the pressure of a 1.7 m tall sand column, equivalent to the even-distributed load of 40 adults with an average body weight of 70 kg standing on one square meter of LandVac. By adopting low-temperature flexible sealing technology, LandVac completely retains the high strength, impact resistance, and other safety attributes of tempered glass. In case of the glass breaks, it shatters into small and less harmful honeycomb-shaped particles.

As one of the new generation energy-saving materials promoted by the nation, LandVac® vacuum insulated glass not only has realized commercial production but also has been successfully listed in the “Catalog of the Recommended Products for Passive Low-energy Buildings” of MOHURD. Thanks to its outstanding advantages in thermal and sound insulation performance, LandVac® is well-received in the passive house project in Urumqi, Xinjiang. In the context of the global promotion of green buildings, LandVac has earned its reputation in the low energy consumption passive house projects with its unparalleled energy properties. It certainly means a wider market prospect for LandVac. In addition, vacuum insulated glass has also a broad range of applications in many areas including green household appliances, transportation, and military development. We are confident that LandVac will make greater contributions to the global efforts in the fields of energy saving, green and environmental protection in the future.
