VacuMax™ Vacuum Insulating Glass (VIG)

Maximize R-values in any Vitro Glass configuration with a VacuMax™ vacuum insulating glass (VIG) unit.

VacuMax™ Vacuum Insulating Glass (VIG) by Vitro - Where the Window Becomes the Wall.

VacuMax™ vacuum insulating glass (VIG) by Vitro Architectural Glass integrates with any traditional (and even non-traditional) glazing system to maximize insulation performance. With an R-value of R14⁺, VacuMax™ VIG is the ultimate in thermal glazing, delivering R-values close to those of a traditional wall.

The new tempered VacuMax™ VIG units can be used alone as nominal ¼” glass to replace monolithic (single-pane) glass without needing to replace the framing system or as a substitute for the interior lite in any double- or triple-glazed insulating glass unit (IGU), where it forms a second airspace and creates a hybrid IGU.

What is Vacuum Insulating Glass (VIG)?

A VacuMax™ VIG unit consists of two lites of 4mm glass separated by a non-leaded proprietary metal 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:

  • Total thickness is just 8.3mm, only slightly thicker than a standard 8mm glass lite.
  • Available in sizes from 12”x12” (0.3m x 0.3m) to 58”x96” (1.45m x 2.45m).

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.

Multi-pane IGUs utilizing VacuMax™ VIG units still include traditional airspaces adjacent to traditional glass lites.

Performance Benefits

Vacumax™ VIG units enhance the performance of any glass configuration by effectively blocking thermal transmission, delivering thermal insulation performance that is 2-4 times better than conventional insulating glass and 6-10 times better than monolithic glass.

Use VacuMax™ VIG to achieve:

  • Extraordinary R-values that deliver energy savings and reduced carbon emissions 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® 60 solar control, low-e glass by Vitro Glass, which can help to further enhance the energy efficiency performance of the IGU. When a VacuMax™ VIG unit is used as the interior lite in a hybrid IGU, the exterior lite is available with the full range of Solarban® glass products and substrates by Vitro glass.

Where to Use VacuMax™ VIG Units

Consider VacuMax™ VIG for exterior glazing applications that require extraordinary insulating performance. VacuMax™ VIG is ideal for residential and commercial projects, including:

  • Renovations
  • New Construction
  • Office buildings
  • Educational institutions
  • Hospitality
  • Healthcare
