VacuMax™ Vacuum Insulating Glass (VIG) by Vitro – Turning Walls into Windows

Vacuum Insulating Glass (VIG) Unit

VacuMax™ vacuum insulating glass (VIG) by Vitro Architectural Glass integrates with any traditional (and even non-traditional) glazing system to maximize insulation performance. With wall-like R-values up to R20, VacuMax™ VIG is the ultimate in thermal glazing.

The newest generation of VacuMax™ VIG is now manufactured exclusively with Solarban® 70 solar-control, low-e glass by Vitro and can be used alone as nominal ¼” glass to replace monolithic (single-pane) glass without needing to replace the framing system. Additionally, a new manufacturing process means the next generation of VacuMax™ VIG units don’t require a vacuum port and feature a getter that’s hidden from view.

What is Vacuum Insulating Glass (VIG)?Back to Top

A VacuMax™ VIG unit consists of two lites of glass, ranging from 4mm to 6mm, separated by a non-leaded proprietary metal edge seal and a vacuum space. The unit’s slim construction and light weight allows it to be incorporated into virtually any traditional glazing system, window frame or curtainwall application.

VacuMax™ VIG Unit Dimensions:

  • Available with a minimum thickness of 8.3 mm (with 4mm lites) and a maximum of 12.3 mm (with 6mm lites).
  • Available in sizes from 12”x12” (0.3m x 0.3m) to 60”x118” (1.5m x 3.0m). Contact your Vitro architectural representative for more details.

Performance Benefits

VacuMax™ VIG units enhance the performance of any glass configuration by effectively blocking thermal transmission, delivering thermal insulation performance that is 3-5x better than conventional insulating glass and up to 20x better than monolithic glass. VacuMax™ VIG also offers extraordinary R-values and delivers energy savings and reduced carbon emissions.

Compare the baseline performance of VacuMax™ VIG units to traditional IGU components and configurations.

Use VacuMax™ VIG to achieve:

  • Extraordinary R-values that deliver energy savings and reduced operational carbon by way of lower Btu usage
  • Longer life compared to competitive VIG products as a result of SGCC -certified tempered safety glass and a flexible, strong, non-leaded proprietary metal seal to ensure higher vacuum capability
  • Increased acoustic performance for dramatic noise reduction
  • Reduced center of glass condensation at temperatures as low as -58° F
  • Flatness and strength due to the VacuMax™ VIG low temperature sealing technology
  • Generous window-to-wall ratios without sacrificing performance or occupant comfort

VacuMax™ VIG units are available with Solarban® 70 solar control, low-e glass by Vitro Glass, which can help to further enhance the energy efficiency performance of the IGU.

Hybrid VacuMax™ VIG Units

Nominal 1" Hybrid VIG Unit

VacuMax™ VIG can also be used as a substitute for the exterior or interior lite in any double- or triple-glazed insulating glass unit (IGU), where it forms a second airspace and creates a hybrid IGU. Multi-pane IGUs utilizing VacuMax™ VIG units still include traditional airspaces adjacent to traditional glass lites.

The simplest and most complex Vitro Glass configurations — from a simple monolithic lite of Starphire Ultra-Clear® glass to a double-glazed IGU with a Solarban® low-e coating on the #2 surface and a bird-friendly pattern on surface #1— can benefit from remarkable performance improvements by replacing the innermost lite with a VacuMax™ VIG unit.
