Vacuum Insulated Glazing
Superior thermal performance. Razor-thin profiles.
Over 133 years of science, perfected for modern architecture.
Arkitectural Glass supplies Vacuum Insulated Glazing for architects, builders, developers, and commercial refrigeration manufacturers. We deliver our 3rd-generation VIG direct to project sites across the United States, Mexico and Canada.
The Science
Vacuum Insulated Glazing works on the same principle as the vacuum flask invented by Sir James Dewar in 1892. By removing the air between two panes of glass, we eliminate convection and conduction — the two primary ways heat transfers through a window.
The result? Glass thinner than traditional IGUs yet dramatically outperforms them. No condensation. No convection. No compromise.
Engineering Detail
Between the two panes of every VIG unit sits an array of micro-pillars — precision-engineered supports that hold the glass in place against the force of atmospheric pressure on the vacuum cavity. Each pillar is barely visible to the naked eye, yet strong enough to support over 90 MPa of compressive load.
Pillars are available in black or white to complement your glass selection. They are most noticeable at close range and in certain lighting — from typical viewing distances, they blend into the glazing.
Like the rivet pattern on an aircraft wing, the pillar array is a signature of the technology at work — the visible proof that science is performing behind the glass.
Why VIG
U-values as low as 0.3 W/m²·K. Keeps warmth in during winter and heat out in summer — reducing HVAC loads year-round.
Starting at just 6.2mm, VIG fits where traditional double or triple glazing cannot — ideal for historic retrofits and slim sightlines.
No air in the cavity means no moisture. Perfect for healthcare, schools, commercial refrigeration, and humid climates.
STC ratings of 39+ dB reduce exterior noise dramatically, creating quieter, more comfortable interior environments.
Head to Head
Both use Low-E coatings. Only one eliminates the gas fill entirely. Here is how Vacuum Insulated Glazing compares to a standard double-glazed IGU with the same Low-E substrate.
| Performance Metric | Double-Glazed IGU (Low-E) | VIG (Low-E) |
|---|---|---|
| Center-of-Glass R-Value | R-3 to R-5 | R-12 to R-20 |
| U-Value (W/m²·K) | 1.2 – 1.8 | 0.3 – 0.5 |
| Overall Thickness | 24 – 32mm | 6.2 – 12.2mm |
| Weight (per sq ft) | 5 – 8 lbs | 3 – 6 lbs |
| Condensation Risk | Possible (gas seal degradation) | Zero — no air in cavity |
| Sound Attenuation (STC) | 28 – 32 dB | 39+ dB |
| Gas Fill Degradation | Yes — argon leaks over time | None — vacuum is permanent |
| Historic Retrofit Compatible | Rarely — too thick for original frames | Yes — fits single-glazed profiles |
| Tested Lifespan | 20 – 25 years | 40+ years (accelerated testing) |
| Edge Seal Technology | Organic polymer sealant | Silver metallic solder (lead-free) |
All values represent typical ranges. Actual performance varies by manufacturer, glass configuration, and Low-E coating selected. VIG values based on 3rd-generation products.
Markets We Serve
Single-pane buildings legally prohibited from changing window profiles. VIG at 6.2mm is the only high-performance solution that fits existing frames. Same sightlines. 3–4x more efficient than IGU. Thin enough to fit where IGU can’t.

Learn More →Like-for-like swap. No construction disruption. STC 39+ dB sound attenuation. IRA energy efficiency credits help offset the premium.
Drop-in upgrade for existing building stock. Utility savings pay back the premium. Subsidy-eligible through federal and state incentive programs.
3–4x more efficient than standard IGU in a profile thinner than standard IGU. Spec-driven projects where the architect already wants the performance. No LEED cert required.
Best-in-class U-value for Class A office, luxury hospitality, and premium residential towers with net zero commitments.
No condensation. Consistent internal climate. Lower energy draw. Ideal for controlled environment agriculture, vertical farms, and cannabis facilities.
Preservation
Most high-performance glazing options are too thick for historic window frames. Traditional double-glazed IGUs start at 24mm — far too wide for original single-glazed profiles. VIG changes the equation entirely.
Where traditional IGUs demand new frames and altered sightlines, VIG drops into existing single-glazed profiles. Landmark buildings achieve modern thermal performance without sacrificing the architecture that earned them protection in the first place.

Sustainability
Vacuum Insulated Glazing can contribute to multiple LEED v4.1 credit categories, helping your project earn points toward Certified, Silver, Gold, or Platinum status.
The highest-value category for glazing. VIG's U-values of 0.3–0.5 W/m²·K dramatically improve energy modeling scores, reducing HVAC loads for both heating and cooling. Up to 20 points are available depending on building type — 16 for schools, 20 for healthcare, 18 for commercial.
VIG contributes to acoustic comfort credits with STC ratings of 39+ dB, and supports daylighting credits through high visible light transmittance — reducing reliance on artificial lighting while maintaining occupant comfort.
VIG's 40+ year tested lifespan supports durability and waste reduction goals. The lead-free metallic edge seal and elimination of gas fills mean fewer materials consumed in manufacturing, reducing embodied carbon compared to triple-glazed alternatives.
VIG's vacuum technology can qualify for innovation credits as a cutting-edge envelope strategy that exceeds baseline requirements. In hot climates like the Southwest, regional priority credits reward cooling load reduction — where VIG excels.
LEED contribution depends on project-specific energy modeling and pathway selected. Product-level LEED certification is currently in process — contact us for current certification status. Consult your LEED AP for project-specific guidance.
Common Questions
VIG uses a sealed vacuum between two glass panes to eliminate convection and conduction — the same principle as a Thermos bottle. It achieves R12–R20 insulation in a profile as thin as 6.2mm, far outperforming traditional double or triple glazed IGUs.
Stand-alone VIG ranges from 6.2mm to 12.2mm — significantly thinner than most double-glazed units. This makes it ideal for historic retrofits where existing frames must be preserved.
Third-generation VIG achieves center-of-glass R-values between R12 and R20, with U-values as low as 0.3 W/m²·K — comparable to a well-insulated wall.
No. Because there is no air in the vacuum cavity, VIG produces zero condensation — making it excellent for healthcare, schools, commercial refrigeration, and humid climates.
Micro-pillars are precision-engineered supports that hold the glass panes apart against atmospheric pressure. Available in black or white, they are barely visible at normal viewing distances.
Current products are warranted for 10–15 years. Most manufacturers have passed accelerated testing for 40+ years, and VIG has been installed in the field for over 30 years.
