SuperVIG® vacuum glass features prominent advantages of slim‑light structure and superior thermal insulation.
Triple‑glazing double‑cavity Low‑E insulated glass delivers decent thermal transmittance performance, yet its overall thickness is more than twice that of SuperVIG® vacuum glass. SuperVIG® vacuum glass achieves thermal transmittance comparable to building walls, even outperforming walls with poor thermal performance. For building projects, it can be defined as a transparent ultra‑thin "wall".
Under high‑vacuum conditions, the glass edges are permanently sealed with lead‑free alloy flexible solder, producing double‑sealed port‑free vacuum glass with superior vacuum performance.
The port‑free design effectively reduces air leakage risks caused by exhaust ports, ensuring product consistency and reliability.
Featuring slim‑light structure and exceptional thermal insulation, SuperVIG® vacuum glass achieves thermal transmittance comparable to building walls, even outperforming walls with poor thermal performance. It can be regarded as a transparent ultra‑thin “wall” for building applications.
