View SpecificationsSweden stands at the forefront of global environmental policy, aiming for absolute carbon neutrality by 2045. A primary pillar of this ambitious target is the transformation of the built environment. Heating and hot water systems in Swedish buildings represent a substantial portion of national energy use, particularly under harsh Nordic winter conditions. As traditional double and triple-pane gas-filled windows hit their physical thermodynamic limits, Vacuum Insulated Glass (VIG) has emerged as the defining technology to redefine Swedish envelope insulation.
Under the guidelines set by Boverket (the Swedish National Board of Housing, Building, and Planning), new constructions and deep retrofits must comply with rigorous primary energy coefficient standards. Conventional glazing solutions require thick, heavy profiles (triple-pane units with Low-E coatings and krypton/argon gas) to achieve the necessary U-values. This approach imposes structural strain, requires thicker profiles, and limits natural light transmission.
“VIG achieves a center-of-glass thermal performance of down to 0.4 W/(m²K), matching the performance of a solid insulated wall in a package only 8.3mm thick.”
By removing the air between two glass panes to create a vacuum environment (below 10-4 Pa), conductive and convective heat transfer are completely eliminated. This enables architects to achieve superior thermal envelopes while preserving the sleek aesthetics of thin, elegant profiles, which is especially critical for historical building preservation in urban zones like Stockholm’s Gamla Stan.
Sweden's climatic conditions demand exceptional mechanical resilience. Winds off the Baltic Sea and heavy snow loads place extreme mechanical stresses on window structures. Tempered VIG solves this challenge. The micro-pillar array dispersed between the glass layers distributes wind pressure evenly across the tempered glass panes, preventing deflection and maintaining the critical vacuum seal under intense external wind pressure and sub-zero temperature differentials.

Sweden hosts significant medical biotech sectors. Our fumed silica VIP boxes and cooler insulation panels ensure the integrity of life-saving therapeutics and vaccines, keeping internal temperatures stable at critical ranges even during Nordic blizzards.
VIG enables compliance with Passivhaus standards in Sweden without bulky profiles. By implementing thin vacuum insulated glass, residential and commercial buildings can slash structural costs, allow more natural light, and drop the envelope U-value to record lows.
From industrial kilns in metallic sectors to plant machinery in Kiruna, nano microporous panels withstand extreme heat loads up to 1000°C. They decrease radiant thermal losses, ensuring safe workspace limits and preserving power supply energy.
For modular luxury lodges in Lapland, maximizing glass area without heat loss is critical. Guest comfort requires views of the Northern Lights without experiencing the sub-zero chill, which is achievable only with advanced VIG assemblies.
The greatest mechanical failure hazard for Vacuum Insulated Glass is loss of vacuum pressure over time. Normal double glazing uses organic polymer seals that allow gas to slowly diffuse into the cavity. For VIG to survive the thermal cycles of Sweden's seasons, it must utilize an inorganic, airtight hermetic seal.
Zerothermo employs a proprietary metal-to-glass edge fusion technology. This process utilizes glass solder and lead-free alloys to create a solid physical connection between the glass sheets, which completely stops any gas molecules from leaking inside. The vacuum layer is backed by high-capacity reactive getters that chemically absorb any trace moisture or gas molecules that outgas from the inner surface over the window's lifespan.
In addition to thermal insulation, VIG provides excellent noise reduction. The lack of air in the vacuum layer blocks high-frequency sounds, making it a perfect solution for Stockholm’s city center developments and residential areas near highways or airports.

Request Price ListWhile traditional triple glazing relies on gas filled cavities to slow down thermal transfer, VIG eliminates gas conduction entirely by maintaining a high vacuum between the panes. VIG achieves center-of-glass U-values of 0.4 - 0.6 W/(m²K), matching the performance of a thick insulated wall. VIG is also much thinner and lighter, which simplifies transport and installation.
Yes, our tempered VIG panels feature an engineered micro-pillar grid that handles extreme pressures and temperature differences. Both panes are tempered to increase safety and resist wind loads up to 6.0 kPa, making them ideal for high-latitude applications.
We use a proprietary metal-to-glass edge seal instead of organic polymers. Combined with our reactive getter tech inside the cavity, it prevents gas diffusion and ensures the vacuum remains stable for over 25 years.
Yes. VIG's thin profile (as low as 8.3mm) fits into traditional timber frames. This allows historic buildings to meet modern energy standards without changing their original look.
