The aim of The Vacuum Glazing Network is to bring PassivGlas™ Vacuum Insulated Glass (VIG) to the forefront of modern architecture by making it as accessible as possible.

A Sustainable Glass Replacement Solution

PassivGlas™ far outclasses the thermal performance of even triple glazing. Energy efficient windows such as those supplied by The Vacuum Glazing Network help keep properties warm during winter with minimal heating. This has been purposely designed as replacement glass for single and double glazed units, forming the core of our sustainability framework and commitment to Carbon Net Zero. The result is a vacuum glazing option that has benefits for both residential properties away from the city, as well as commercial buildings that don’t get direct sunlight.

A Double Glazing Alternative

If you’re looking to invest in glass that falls in line with the government’s plans for Carbon Net Zero in 2050, vacuum glazing is the clear choice. PassivGlas™ is an amazing heat and sound insulator, while being available in thicknesses that are less than triple and double glazing panes.

PassivGlas™ Product Range

PassivGlas™ Linear

PassivGlas™ is an advanced fenestration technology that involves creating a highly insulating window by enclosing two glass panes with a micro-thin gap in between.

PassivGlas™ Ultimate

PassivGlas™ is an advanced fenestration technology that involves creating a highly insulating retrofit unit by enclosing a PassivGlas™ VIG with a thermally broken spacer bar airgap and the addition of a fully toughened glass.

Vacuum Glazing Replacement and Refurbishment

PassivGlas™ is intended for fitting within both new and existing window frames. For glass replacement services, this is very straightforward as the frame doesn’t need replacing so long as it has suitable edge coverage. The installer can also discreetly conceal the getter and edge seal to create a sleek modern appearance. Refurbishing heritage buildings and other old units is straightforward too, as the window frame doesn’t need to be replaced along with the glass. There is the option for the dots in PassivGlas™ to be clear, making the glass ideal for commercial glazing applications.

Applications For
Vacuum Insulated Glass

There are many sectors which can make use of performance vacuum glazing, either for aesthetic or practical purposes. For instance, many technical industries require consistent ambient temperatures for their processes. Installing vacuum insulated glass windows allows businesses in these industries to improve the energy efficiency of their buildings, thereby lowering operational costs. It can also be installed in commercial fridge/freezers with great reduced energy consumption and carbon reduction capabilities.

Vacuum Glazing for Heritage Buildings

Due to the sleek and ergonomic design of PassivGlas™ vacuum glazing, panes can be installed with minimal reframing work. This is ideal for listed buildings and other old properties. Our glass allows the cultural significance of UK heritage properties to remain without compromising the commitment to improving thermal efficiency. Furthermore, the installation of PassivGlas™ contributes to the overall comfort of visitors within heritage buildings.

Long Lasting and Reliable Vacuum Insulation

Quality vacuum glazed glass retains its effectiveness for longer than double glazing products. Its lifespan has exceeded 25 years in a vast range of real-world environments, making PassivGlas™ a viable option for improving sustainability and lowering property costs. Unlike many other kinds of VIG, PassivGlas™ is supplied without an extraction port. This makes it a more aesthetic option for reducing heat and noise pollution within a building.

The science of PassivGlas™

Vacuum glazing is the technique used for creating highly insulating glass such as PassivGlas™. It ensures quality insulation from temperature and sound by enclosing two panes of glass with a micro-thin gap in between. During this advanced process, any moisture and gases present between the panes are removed. This leads to the creation a vacuum layer between the glass, which massively reduces loss of heat due to conduction and convection. It’s this feature that makes PassivGlas™ an exceedingly effective insulation method for windows.
