Vacuum Glazed Windows

Vacuum glazed Vacuum glazed

The Future of Windows

Vacuum glazing is an advanced window technology that offers superior insulation compared to traditional double glazing. Similar to double glazing, it uses two glass panes separated by a cavity, but instead of air filling the cavity, the air is removed to create a vacuum. This vacuum acts as an excellent thermal barrier because there are no gas molecules to transfer heat between the panes of glass.

Ideal for renovations in heritage areas, high-performance buildings and in situations where weight reduction is crucial, vacuum glazed sash and casement windows offer superior insulating properties, sound reduction, and a thinner profile that helps to preserve the aesthetics of historical buildings.

Heritage Vacuum Glazing vs. Optimum Vacuum Glazing

TRC offers both LandVac Hertiage Vacuum Glazing and Optimum Vacuum Glazing. LandVac heritage glazing seamlessly blends modern technology with classic aesthetics. Unlike conventional double glazing, this innovative design maintains the original sightlines while delivering superior insulation and noise reduction, making it ideal for conservation areas where preserving the architectural character is crucial.

LandVac Optimum glazing, meanwhile, sets a new standard in performance and reliability. This innovative vacuum insulated glass unit boasts an impressive thermal insulation value of up to 0.4 W/m²K, significantly exceeding the industry average. Buildings equipped with LandVac Optimum can achieve substantial energy savings, translating to lower energy bills and a reduced environmental footprint.

Vacuum Glazing vs. Double and Triple Glazing

Compared to standard double glazing and triple glazing, vacuum glazing has a number of benefits, including more energy efficiency and less heat loss, better insulation, higher noise reduction, better light transmission, a slimmer profile, and a longer service life.

LandVac vacuum glazing offers a perfect solution for architects seeking both beauty and performance. Its ultra-thin profile seamlessly integrates with heritage projects, preserving architectural integrity. LandVac prioritises comfort with exceptional thermal performance and superior insulation properties (centre-pane U-values of 0.4W/m²K) and superior G-values, keeping properties warm and bright. LandVac also prioritises safety with two panes of 4mm toughened glass and boasts sustainability as the units are fully recyclable and eliminate energy-intensive noble gases.
