Vacuum glazed timber windows offer superior insulation and thermal performance while preserving the aesthetic appeal of heritage properties. This advanced technology combines the charm of traditional timber frames with cutting-edge glazing, providing an ideal solution for listed buildings and conservation areas.
Vacuum glazed timber windows offer superior insulation and thermal performance while preserving the aesthetic appeal of heritage properties. This advanced technology combines the charm of traditional timber frames with cutting-edge glazing, providing an ideal solution for listed buildings and conservation areas.

Vacuum glazed timber windows utilise two panes of glass separated by a vacuum, known as vacuum double glazing, eliminating air and significantly reducing heat transfer. This innovative approach, also known as vacuum-insulated glazing or insulated glazing, results in exceptional thermal insulation, improved sound reduction, and a slim profile that maintains the integrity of historical window designs. Our vacuum glazed timber windows, featuring this advanced type of glass, are perfect for renovations in heritage areas and high-performance buildings.

The Science Behind Vacuum Glazed Windows

Vacuum glazed windows achieve their superior performance by eliminating air between the glass panes, minimising thermal conductivity. This technology surpasses traditional double and triple glazing in insulation properties, offering significant benefits for energy efficiency and comfort. The absence of air also reduces the ‘double image’ effect often seen in standard double glazing, making it ideal for heritage properties. With its ability to provide excellent insulation through its use of a highly efficient insulator, vacuum glazing represents a perfect balance of performance and aesthetics for historical buildings with great insulation properties.

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.

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. Vacuum glazing 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. Vacuum glazing 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.

How does vacuum glazing work?

Vacuum glazing works by creating an insulating vacuum between two panes of glass, reducing heat transfer and improving energy efficiency. This process involves removing air from the gap between the panes, preventing heat loss or gain through the window and providing better thermal performance.

Our vacuum glazed timber windows are designed to meet the unique challenges of listed buildings and conservation areas. They offer the charm and authenticity of traditional timber frames combined with state-of-the-art glazing technology. This combination allows for significant improvements in energy efficiency and comfort without compromising the historical integrity of the property. In older buildings, where single glazing is often the norm, our vacuum glazed timber windows provide a modern solution while still preserving the heritage of historic buildings.

Testimonial

Both the works and resident liason were an excellent standard and the works were successfully completed to programme and budgets.
