Green buildings, low-carbon certification, and passive homes are now common topics across the vacuum insulated glass industry.
But few ask a more basic question: Is vacuum glass environmentally friendly?
- Some Vacuum Insulated Glass Uses Lead in the Edge Seal
Glass-frit solder commonly uses lead oxide as a key component to lower the sealing temperature.
Lead is a heavy metal that can seriously harm human health and the environment. Both the EU RoHS Directive and REACH Regulation strictly restrict its use.
This means vacuum glass made with lead-containing glass-frit edge seals cannot enter the EU market, qualify for green building certification, or be used in projects with strict environmental requirements.
Even with lead-free glass-frit solder, some silver-paste products may meet RoHS requirements but still fail the stricter REACH requirements.
SuperVIG® Vacuum Insulated Glazing: RoHS and REACH Certified
The SuperVIG® all-metal sealing process uses lead-free active alloy solder with no harmful heavy metals and complies with both RoHS and REACH, two of the world’s strictest environmental material standards.
This means:
✅ Suitable for the EU and other major global markets
✅ Suitable for green building certification projects
✅ Meets the strict environmental requirements of medical, educational, and similar buildings
✅ Suitable for health-sensitive spaces such as children’s rooms and bedrooms
Our Undertaking of Environmental Responsibility
For architects, developers, and building owners, choosing vacuum glass with both certifications is not only about compliance. It also reflects a commitment to occupant health.
SuperVIG® believes good building materials should be safe for people and the environment throughout their service life.
That commitment starts with the choice of edge-sealing materials.
Green buildings start with every pane of glass.
