Fridge tech leads to Vacuum IGU launch
13th November 2018

GUARDIAN GLASS has launched its own slim, vacuum-based IGU system, Guardian Vacuum IG, using technology used in commercial refrigeration units.

The system takes two glass panes and seals them airtight. A vacuum is created in the space between the two fully tempered glass panes, which are held apart by almost microscopic pillars.

Compared to standard triple IGUs, Guardian Vacuum IG is thinner and lighter, it is said to have a better thermal insulating performance, a higher light transmission and a lower reflection. The thermal insulation performance of Guardian Vacuum IG remains the same regardless of the angle at which it is installed (from vertical to horizontal).

Guardian Vacuum IG was first deployed in retail refrigerator doors where it provides uninterrupted views of refrigerated goods.

Greg Kemenah, director, Guardian Vacuum IG said: “Vacuum-sealed glass units with low-E coatings can achieve thermal insulating performance of R-12 (Ug equivalent value is 0.47 W/m2K) with a profile that is only 8.3mm thick. This results in an insulating glass unit that is 75% thinner, has 33% less weight and exceeds the performance of triple-pane, low-E glazings.”

He added that, with building codes becoming more stringent, Guardian Vacuum IG will enable a world of possibilities for other applications emerging across multiple industries, in particular, windows. In the United States, Guardian Vacuum IG is now also available for new builds and windows’ retrofit.
