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

Unlike traditional double-glazed windows which use air or gas as an insulating layer, vacuum glazing employs a vacuum to minimise heat transfer through the window.

The elimination of air or gas from the gap significantly reduces conduction and convection heat losses, making vacuum glazing one of the most efficient insulation methods for windows.

PassivGlas offers tempered glass as standard with the best U values of 0.47W/m2K while keeping up to 80% light transmittance.

The U Value measures the rate of heat transfer through a material, and lower values indicate superior insulating properties.

The exceptional thermal efficiency of vacuum glazing helps to maintain stable indoor temperatures, reducing the need for artificial heating or cooling and leading to substantial savings.

Ultrathin But Strong – Despite its incredibly thin profile, vacuum glazing is remarkably robust and durable. The vacuum-sealed gap between the glass panes prevents warping or bending, ensuring the integrity of the window over time.

The glass used in vacuum glazing is typically thinner than that of conventional double glazed windows, reducing material usage whilst improving performance.

This make vacuum glazed window a more sustainable choice, as they require fewer raw materials and therefore, less energy to produce. PassivGlas come toughened as standard.

Enhanced Sound Insulation – In addition to its thermal insulating properties, vacuum glazing also offers exceptional sound insulating qualities.

The vacuum layer acts as a buffer that dampens external noise, creating a peaceful and quiet indoor environment.

This feature is particularly advantageous for properties located in busy urban areas or near noisy environments, providing a more comfortable and tranquil living space.

New Build Projects – Vacuum glazing is the prefect choice for your new build project. It enables you to keep the slim design of double glazed units whilst increasing your energy rating to better than that of triple glazing.

It can be fitted into timber frames due to its super slim design to eliminate the unsightly appearance of spacer bars.

By keeping the frames slimmer and using fully recyclable glass, the carbon footprint of the build is reduced and energy savings are high. With a life expectancy of over 25 years, it contributes to a future proof build with higher customer satisfaction.

Preservation of Historical Architecture – Vacuum glazing is a game changer for preserving the historical charm of older building and heritage site. Traditional single glazed windows are often inadequate in terms of thermal performance and can be challenging to upgrade without compromising the buildings original aesthetics.

Vacuum glazing allows historical structures to maintain their classic appearance whilst vastly improving energy efficiency. This breakthrough technology opens up new possibilities for retrofitting projects and sustainable preservation of architectural heritage, including EnerPHit projects.
