Applications

Architecture

LandVac is thin, lightweight, and safe. The remarkable features including thermal and sound insulation make it a perfect fit for green buildings.
Applications: Doors, windows, curtain walls, and skylights for upscale commercial and residential buildings, public facilities, as well as landmark structures.

Certifications

1. ATI: Founded in 1970, ATI is a leading certification body for architectural engineering testing and inspection in Northern America.

2. ift: ift is a world-renowned building materials testing institution in Germany.

3. ANSI: Established in 1918, ANSI is the center for U.S. national standards.

Quality Assurance

Low temperature sealing technology: By adopting low-melting-point metal as the sealing material, successfully solved the world-class problem of tempered glass annealing during production.
High Vacuum Sealing Off technology: air removing and sealing are done in an Ultra High Vacuum environment, it guarantees the consistency of high vacuum in LandVac.
Flat sealing technology: To make product safer and better looking and allow easier and more cost efficient packaging, storage, and transportation.
Flexible edge sealing technology: Flexible-sealing materials can withstand more severe thermal shock and larger temperature difference between the surfaces, improving the durability of LandVac significantly.
Intelligent control technology: The intelligent continuous production line optimizes the production management and control while guaranteeing the quality of LandVac.

After eight years of endeavor, LandGlass developed the automatic fully tempered vacuum insulated glass production line. The production line consists of fully automatic spacer placement, high precision automatic combining of glass sheets, continuous removing air in high vacuum environment, and state-of-the-art Cyclone series JetConvection tempering furnace along with full lines of other top brands glass processing equipment. With carefully selected high quality glass sheets, application of self-developed five major technologies, and implementation of monitoring and inspection measures far exceeding industrial standards, LandGlass warrants the Superior quality of LandVac.

LandGlass has established high standard quality control system for the raw material checking, process monitoring and final products inspection with the world's leading testing instruments and technologies, focusing on safety and thermal insulation performance of LandVac. We can ensure that every piece of LandVac is of superior quality.
