Austria's commitment to the European Green Deal, reinforced locally by the Austrian Institute of Construction Engineering through OIB Guideline 6 (OIB-Richtlinie 6 - Energieeinsparung und Wärmeschutz), has set aggressive targets for building decarbonization. Traditional triple-pane glazing, while thermally effective, faces structural limits due to its extreme weight, thickness, and high embodied carbon. In historical city centers like Vienna, Graz, and Salzburg, where facade preservation regulations (Altbauerhaltung) prevent structural frame widening, traditional thermal glazing cannot be installed.
This physical constraint drives the soaring demand for Vacuum Insulated Glass (VIG). Achieving center-of-glass U-values as low as 0.4 to 0.6 W/(m²K) within a profile of under 10 millimeters, VIG delivers the thermal efficiency of a solid wall while keeping the lightweight footprint of single or slim double glazing. Austrian architects and construction developers are rapidly specifying VIG to achieve Passive House targets without compromising historic structural integrity.
In alpine areas such as Tyrol and Vorarlberg, buildings face structural demands from snow loads and severe temperature differentials. Vacuum Insulated Glass must endure extreme pressure cycles. Because VIG relies on a vacuum cavity supported by micro-spacers, it bypasses the expansion and contraction failures typical of gas-filled (Argon/Krypton) triple glazing at high altitudes. This makes it an ideal solution for luxury alpine hotels, high-altitude research installations, and premium Austrian residential projects.
Furthermore, Austria's industrial sectors—ranging from advanced commercial refrigeration to bio-pharmaceutical logistics hubs in Linz—require high-performance thermal barriers to maintain stable cold storage conditions. Vacuum insulation panels (VIPs) and high-temperature nano-microporous materials are no longer niche products; they are critical building blocks for modern cold-chain infrastructure, ensuring energy savings and compliance with strict EU temperature-monitoring mandates.
Procuring high-performance architectural materials like Vacuum Insulated Glass and Vacuum Insulation Panels for European markets requires navigating complex logistical, regulatory, and quality hurdles. Austrian contractors require materials certified to European standards (such as EN 1279 for insulating glass durability and CE marks). The challenge lies in scaling production to achieve cost-efficiency without sacrificing reliability.
At Zerothermo Technology, our production facilities are built on advanced Factory 4.0 manufacturing processes. Strategically positioned as a subsidiary of the CBVAC Group, our Nanchong facility employs automated high-vacuum sealing lines, robotic glass handling, and real-time helium mass spectrometer leak detection. This automated precision ensures our VIG units retain their high vacuum (10^-4 Pa) for decades, preventing edge seal failures and condensation.
By combining localized production scale with global supply chain management, we solve the common trade-off between price and performance. Our Austrian and European procurement partners benefit from factory-direct quotes, tailored packaging to prevent transit damage, and full documentation to support regional building approvals.

How microporous materials reduce thermal conductivity in specialized industrial machinery and laboratory testing apparatus.
VIG delivers equivalent or superior thermal insulation compared to gas-filled triple glazing, but at a fraction of the thickness (typically 8.3mm vs 36mm+) and weight. This prevents structural strain on window sashes. Additionally, triple glazing can suffer from gas leakage and performance loss at higher altitudes (e.g., in the Austrian Alps), whereas VIG utilizes a physical vacuum that remains stable across changing atmospheric pressures and elevations.
Yes. Our manufacturing processes conform to international standards, and we construct VIG units using high-durability, safety-tempered glass layers that meet the physical requirements of EN 12150 and EN 1279. We work closely with Austrian distributors and installers to supply the necessary technical documentation and material testing details required by local authorities.
Our standard double-glazed VIG units achieve a center-of-glass U-value down to 0.4 - 0.6 W/(m²K), depending on low-E coating selections and glass configuration. By combining VIG with an additional insulated glass cavity (hybrid VIG), center U-values can reach below 0.38 W/(m²K), matching solid wall insulation parameters.
VIG panels rely on a vacuum-tight edge seal and micro-spacer support array, which limits extreme curves. However, we can construct flat shaped panels (such as triangles, parallelograms, or arched tops) and offer customized low-E coatings, frosted finishes, and decorative patterns. Contact our engineering team with your drawings for custom feasibility assessments.
We package our glass inside heavy-duty, reinforced wooden crates lined with high-density shock-absorbing foam. Moisture-barrier desiccant is added to prevent condensation during transport. Our logistics team coordinates sea, rail, or air delivery directly to your building site or distribution warehouse in Austria, with full insurance and tracking options.
