Noise Reduction Series-LUOYANG LANDVAC VIG SCIENCE & TECHNOLOGY CO., LTD

Noise Reduction Series

Various applications with a full frequency range of noise blocking, creating a peaceful environment far from the madding crowd.

Weighted sound reduction≥39dB, which is 1.5 times that of ordinary insulated glass;

Customized to suit various needs, our composite noise reduction LandVac, tailored for specific scenarios such as overpasses and airports, can achieve a noise reduction level of up to 52dB;

Patented noise reduction technology further enhances sound insulation.

Energy Conservation

U-value as low as 0.4W/(m²•K). A 8.3 mm thick LandVac has better thermal insulation effect than the 1.5m 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, significantly reducing heat exchange and boosting the energy efficiency of cold chain appliances.

Outstanding Adaptability

Since there is no thermal expansion or contraction in the high vacuum chamber of LandVac, the use of LandVac is not limited by geographical locations, elevation, or installation angle.

Thanks to the high vacuum chamber of LandVac, there is no thermal expansion or contraction even if the elevation of the location where it's used is largely different from where it's manufactured.

Furthermore, unlike insulated glass, whether it’s mounted horizontally or at an angle, the U-value of LandVac remains constant, which ensures excellent energy-saving effect，especially suitable for skylights, sunroom, daylighting roof, and applications in other special spaces.

Free of Condensation

Tempered and Safe

Thin and lightweight structure

Super Long Life

Lead-free

Free of Condensation

Remain condensation-free when the temperature difference between the two sides exceeds 70℃. The ultra-low dew point allows LandVac in buildings and freezers to maintain their exceptional transparency.

LandVac effectively eliminates the condensation in the vacuum chamber. Meanwhile, the high thermal resistance property significantly lowers the dew point of the LandVac surface as well.

Tempered and Safe

Completely retains the high strength, impact resistance, and other safety characteristics of tempered glass with its unique FLAS Flexible Lead-free Alloy Sentry technology.

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.

Thin and lightweight structure

A piece of 8.3 mm thick LandVac weighs only 20kg/㎡. It reduces the use of materials while extending the service life of hardware. The costs on storage and logistics are also significantly reduced.

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.

Super Long Life

The service life expectancy of LandVac exceeds 25 years.

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.

Lead-free

The Testing Report from CTI, which is authorized by RoHS EU, has witnessed the outstanding environmental-friendly performance of LandVac.

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