About VIG

Window

History

Vacuum insulated glass was developed in the late 1990s to preserve Grade II heritage timber. Vacuum glazing now fits all timber, uPVC and metal windows from Gothic Regency to Grand Designs residential, civic and commercial. At 0.4U and 38dB, it exceeds most buildings’ needs with just a 6.2mm pane which can then be double glazed or laminated to anything else for specialist needs.

How VIG is made

Vacuum glazing is double glazing with a tiny 0.2mm cavity at very high vacuum giving 0.5Ug down to 0.3Ug with low-E coatings.

Metal or glass seals and ‘getters’ hold the vacuum for 40 years and micro-pillars maintain the gap. The selection of these elements are chosen to suit the glazing aesthetics and performance requirements.
