LandVac, Exceeding Expectations!
LandVac is installed in many architectural projects by its outstanding performance and reliable quality.
Reduce the usage of HVAC systems to enhance natural comfort and to stay healthy;
Compared with insulated glass, the energy consumption per unit of floor area is reduced by approximately 20% ① ;
The comprehensive energy-saving performance of the fenestration system has been easily improved with the support of LandVac® Superstructure technology and adaption to different frame profiles.
① Taking Harbin as an example (located in the northeast of China, usually -38 ℃ in winter) , at 30% window-to-wall ratio (WWR), the energy consumption per unit of floor area is reduced by approximately 20% compared with the insulated glass of equivalent size.
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.
Restore the original transparency of high-end curtain walls and display windows in cold winter.
Note: Test conditions: Indoor temperature at 25℃, outdoor temperature at -50℃, with relative humidity at 70%.
Super Long Life
Tempered and Safe
Thin and lightweight structure
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.
LandVac Energy saving Series products have been successfully used in the projects of many well-known domestic and international enterprises, such as Shandong passive house kindergarten, Hunchun border post, and Denmark Velux, Country Garden, and Poly Group. LandVac is highly recognized in construction, energy-saving, and many other fields.
