Discover our comprehensive collection of industrial vacuum insulated products, built to withstand challenging environments and deliver unparalleled energy savings.
Building envelope dynamics are undergoing a radical shift as energy mandates, zero-carbon pledges, and urbanization force developers and architects to seek high-performance building components. Traditionally, double pane and triple pane insulated glass units (IGUs) filled with inert gases like argon or krypton served as standard thermal barriers. However, these systems are constrained by conduction and convection through the gas fill. The future belongs to Double Pane Vacuum Insulated Glass (VIG).
By extracting gas from the sealed space between two glass panes to establish a vacuum level below 0.1 Pascals, convective and conductive heat transfer is practically eliminated. The result is a glazing system that matches the thickness of a single pane but delivers the insulation performance of a traditional thick, heavy triple-pane assembly. Zerothermo Technology, operating under the CBVAC Group, has engineered advanced vacuum-insulated glass architectures that optimize energy efficiency and thermal integrity across residential, commercial, and extreme industrial landscapes.
According to architectural energy simulations, retrofitting single or early-generation double glazing with advanced vacuum-sealed insulated glass reduces HVAC loads by up to 34% in cold climates and 28% in hot, humid climates. This represents the single highest information gain factor for commercial designers prioritizing long-term ESG compliance.
From the European Energy Performance of Buildings Directive (EPBD) to LEED Platinum criteria in the Americas, structural standards demand a massive drop in building operational emissions. Double pane vacuum windows represent a key technological pathway. Because structural frames account for substantial cold bridges, minimizing glass edge losses and reducing structural loads are critical objectives.

View More +At the center of double pane vacuum window manufacturing is the structural support system. Because an internal vacuum exerts a continuous atmospheric pressure of approximately 10 tons per square meter, the glass panes would collapse against each other without structural stabilization. Micro-spacers, generally measuring between 0.3mm to 0.5mm in diameter and placed at precise grid intervals (typically 20mm to 40mm), maintain structural separation.
The selection of spacer material is critical to performance. High-strength stainless steel or advanced ceramic microspheres minimize point-contact conductive thermal bridging. Simultaneously, edge sealing remains the primary determinant of long-term vacuum retention. Conventional organic sealants degrade and leak over time under UV exposure and thermal expansion stress. Modern double pane vacuum windows utilize glass-solder materials or flexible metal alloy sealing methods that undergo high-temperature fusion. This creates a true hermetic seal, guaranteeing a service lifespan of 25 to 50 years.

The commercial deployment of vacuum glass and thermal barrier technologies has advanced rapidly. Currently, manufacturing is highly consolidated across advanced economies in East Asia and Western Europe. Substantial investments in automated vacuum sealing ovens and high-vacuum sputtering systems have scaled production capacity.
In addition to building integration, industrial processes rely heavily on vacuum insulation panels (VIPs). Cold chain logistics, clean room walls, marine insulation, high-temperature furnace lining, and electric vehicle battery boxes use VIPs to minimize thermal footprint while maximizing safety. As the demand for cryogenic shipping containers grows, fumed silica and PU foam vacuum insulation panels remain indispensable to global distribution networks.
