Vacuum glazing is similar to double glazing, only that the cavity between panes is a vacuum. The main advantage of vacuum glazing is that it not only performs well but has only a small cavity, which means the glazed units are thin and light in comparison to standard units.

This type of unit is often the favoured option for historical buildings because vacuum units can be installed as individual panes between the transom and mullions of traditional timber frame windows. The thickness of a vacuum sealed units can be a low as 6mm, which is less than half the thickness of traditional double glazed units (around 20mm) which means in some cases they can even be installed within existing or refurbished timber frames. The performance of such windows can be from around 1.0 W/M2. K down to 0.5 W/M2.K in a unit, which again is considerably lower than the 1.2 to 3.7 W/(m²K) of standard double glazed units.

The cost of a vacuum glazed units is likely to be higher than standard double glazed units because of the precision nature of their design and manufacture. The natural effect of having a vacuum between the glazing panes is that the panes want to pull together, they are prevented from doing so through the insertion of tiny micro-spacers, less than a 1mm in diameter laid in a regular grid between the panes. These micro spacers are transparent and tiny so can often barely be seen.

The concept for vacuum glazing itself was developed as a proof of concept in the 1990's at the University of Sydney with initial commercialisation by Nippon Sheet Glass, Japan, in 1996. Pilkington glass consider their own SpaciaTM glazed unit to have as been the world's first commerically available vacuum glazing, with sales startiing a year later in 1997.

Pilkington Spacia™ is one vacuum sealed product available from Pilkington that offers the thermal performance of conventional double glazing in the same thickness as a single glass pane. It balances historical preservation with modern comfort and environmental requirements, and a diagram of the how a pane is made is given here, courtesy of Pilkington.
