In the context of the global green energy transition, building envelopes account for over 30% of structural thermal loss. Standard insulation methodologies rely on low thermal conductivity materials which reduce heat flow but fail to eliminate molecular conduction and convection. Vacuum Insulated Glass (VIG) solves this constraint by creating a micro-cavity under extreme negative pressure, mitigating thermal transfer at the molecular level.
Standard double-paned insulated glass units (IGUs) containing Argon show a typical U-value of 1.2 to 1.6 W/(m²·K). High-spec tempered VIG drops this value to less than 0.4 - 0.6 W/(m²·K). This represents a thermal barrier equivalent to a brick wall but at a fraction of the structural load.
The primary failure point of low-quality VIG is vacuum degradation due to gas permeation. Zerothermo utilizes inorganic glass solder and advanced laser sealing systems to guarantee a permanent hermetic seal, keeping vacuum pressure below 10⁻⁴ Pa.
To counter atmospheric pressure of 10 tons per square meter, microscopic pillars are arranged in a precise grid pattern. Zerothermo's sub-millimeter support grids balance mechanical load and thermal bridging while minimizing visible refraction.
VIG pricing is determined by configuration variables, including glass layer thicknesses, tempered safety status, lamination requirements, gas-fill hybrids, shape geometry, and spacer distributions. To assist project designers, procurement engineers, and system integrators, we outline the primary pricing structures and variables below.
| Glazing System Type | Configuration Details | Thermal U-Value (W/m²·K) | Acoustic performance (Rw dB) | Estimated Base Price Range (USD/Sqm) |
|---|---|---|---|---|
| Standard Tempered VIG | 4mm Tempered + 0.3V + 4mm Tempered | 0.50 - 0.60 | 35 - 37 | $180 - $260 |
| Hybrid High-Spec IGU VIG | 4T + 0.3V + 4T + 12Ar + 4 Low-E | 0.38 - 0.45 | 39 - 42 | $270 - $350 |
| Laminated Safety VIG | 5T + 0.3V + 5T + PVB/SGP + 5T | 0.48 - 0.55 | 40 - 43 | $320 - $450 |
| Triple Glazed VIG | 4T + 0.3V + 4T + 0.3V + 4T | 0.28 - 0.35 | 42 - 45 | $400 - $550 |

Special sizes (beyond the range of ANSI/ASME/DIN and other standards) are produced according to customers' drawings or technical parameters.
Square, oval or other special shaped flanges. Oversize/small diameter: such as diameter over 60 inches or micro precision flanges.
Engineered according to custom parameters for high-grade vacuum systems, ensuring optimal sealing integrity.
As governments enforce stricter energy criteria—such as the recast of the EU Energy Performance of Buildings Directive (EPBD), Germany's GEG rules, and North America’s Energy Star Version 7.0—the construction industry faces demanding efficiency standards. Standard double glazing is no longer sufficient to meet next-generation criteria.
Vacuum Insulated Glass delivers low U-values within an overall thickness of 8.3mm to 12.3mm. This eliminates the thick, heavy frames required by triple-pane IGUs. Retrofitting historical structures becomes possible without altering original frames or facade profiles.
Thermal stress between inner and outer glass panes can lead to deflection and seal failures. The micro-spacer grid coupled with resilient edge soldering absorbs physical deformation, keeping the unit structurally stable from -40°C to +80°C.
Conventional double-paned systems experience internal condensation as desiccant materials degrade over time. In a VIG setup, the internal space is a high-grade vacuum, eliminating condensation and maintaining clarity across the product lifetime.
