VIG Technologies, LLC proudly serves as the exclusive North American distributor for the LandVac® division of Luoyang Landglass Technologies Co., Ltd. At AIA, at booth #4610 this technology will be on display.
The VIG Technologies LandVac VIG has outstanding performance in thermal (U-Value 0.48 / R-Value 12 and up) and sound insulation (33 STC / 32 OITC) while retaining the strength (±7200 PA (± 150.38 psf) and safety (SGCC certified) of the glass at a high level.
Other key attributes:
LandVac is an all new generation tempered vacuum insulating glass developed by LandGlass with independent intellectual property rights. Using LandGlass’ exclave low temperature sealing technology, the product has outstanding features in thermal and sound insulation while retaining the strength and safety of the glass at a high level. LandVac leads the trend of glass applications in green building and upscale home appliances with a new standard for the quality of life.
LandVac has a high vacuum chamber that eliminates any gas heat transfer. By using high-performance Low-E coating, it also considerably suppresses radiation heat transfer and reduces the U-value of LandVac to 0.55W/(m²*k).
The thermal insulation performance of LandVac is 2-4 times better than insulated glass and 6-10 times than single pane glass. Using LandVac alone will meet all international passive houses heat transfer requirements on windows and doors.
At the same U-Value, in comparison with triple-pane insulated glass, LandVac weighs less and is much thinner. Less Low-E glass panes promises higher transmittance and improved optical transparency.
By the adoption of flexible metal edge seal, LandVac has much higher resistance against thermal expansion or contraction caused by the temperature difference between inner and outer surface, free of concerns over seal failure due the organic sealing materials aging.
Moreover, the high vacuum chamber of LandVac provides better protection to off line Low-E coating. With the assistance of built-in high efficiency getter material, LandVac can sustain its superior performance against harsh environments and material aging.
Thanks to the high vacuum chamber of LandVac, there will be no expansion or contraction even if the elevation of the location where it’s used is largely different from where it’s manufactured. The heat transfer coefficient of LandVac remains constant regardless of whether it’s mounted horizontally or with an angle, making it suitable for installation at any position around the building.
The high vacuum chamber of LandVac effectively blocks sound transmission with a weighted sound isolation from 39dB to 43dB, generating a remarkable soundproof effect against mid and low frequency noises such as traffic noises that disturb our daily lives the most.
As the world leader in glass processing solutions, LandGlass has profound expertise in core technologies for tempering equipment and tempered glass. With safety glass in mind, LandGlass devoted many years of R&D work to integrate vacuum glass tempering with LandGlass’ exclusive vacuum glass manufacturing technology.
As a result, LandVac® emerged. LandVac® is a new generation of fully tempered safety vacuum glass developed by LandGlass with independent intellectual property rights
