Why Choose Vacuum Glazing?


Vacuum glazing utilizes cutting-edge technology to produce energy-efficient glass units with outstanding thermal insulation properties that far surpass those achieved through traditional double—or triple-glazed glasses. It is the best way to find the tempered vacuum glazing.

This device consists of two sheets of toughened glass separated by an air gap, leaving a gap of 0.3 mm, which is then evacuated. Micro-pillars evenly spaced across both panes are used to maintain a vacuum between them, maintain separation, and ensure adequate vacuum conditions are created for operation.

1. Safety

Vacuum glazing offers an effective alternative to conventional double glazing. Constructed as a fully bonded unit with toughened glass throughout and featuring an inconspicuous vacuum gap with barely visible micro-pillars between each pane of glass, vacuum glazing delivers superior thermal performance without the bulk and weight associated with traditional double glazing or the need to add frame insulation. Furthermore, it can even be fitted into existing timber window frames in historic buildings without affecting architectural integrity or changing its architectural integrity.

Mechanical properties of vacuum glazing can be significantly influenced by the number, distribution, spacing, and arrangement of support pillars. In this study, the objective was to analyze the mechanical performance of double-evacuated glass using various numbers and spacings of vacant support pillars as a support structure.

Vacant pillars can have serious ramifications on the mechanical properties of vacuum-insulating glass, as they can easily lead to an uneven distribution of stress that leads to deformation and damage of glass sheets. However, their effects can be reduced with multi-pass supports; each section’s pillars feature different passage times, which decrease thermal conductivity by cutting the thermal conductivity of each section’s pillars.

Vacuum-glazed units not only reduce accidental injuries, but they’re also highly durable and resistant to external pressures – the air in their cavities acts as a cushion between panes of glass and their frames, protecting them from environmental stresses.

Vacuum-insulated glass offers several advantages over other forms of home glazing, including improved sound reduction. LandVac vacuum glazing products are manufactured in the UK by a family-owned and operated business with more than 25 years of experience. They boast an industry-leading 15-year warranty and a lifespan exceeding double—or triple-glazing products.

LandVac’s innovative approach to insulation boasts center-pane U-values of just 0.4 W/m2K and outstanding G-values, offering energy efficiency that far surpasses double or triple glazing and acoustic performance that rivals laminated acoustic glazing. In addition, their technology enables ultra-thin vacuum glazing solutions that can fit seamlessly into historically significant buildings without altering their original architectural aesthetic.

2. Low-noise

Vacuum glazing provides superior sound insulation, with noise levels reduced by as much as 40% when compared with traditional double-glazing. This is thanks to its highly efficient construction, which includes low thermal conductivity and the ability to trap air between panes of glass. In addition, vacuum glazing is extremely thin, so it can easily fit into existing frames without needing additional bulky frames, thereby cutting installation time and costs significantly.

Vacuum glazing requires micro-spacers—small objects evenly dispersed between panes of glass that create an air gap to prevent them from touching. These spacers are typically made of durable materials like metal or glass and sealed with high-strength sealants to ensure they won’t fall out over time.

Additionally, to spacers, both panes of glass will receive a special coating designed to reduce radiant heat transfer by up to 75% and help you save energy costs while improving comfort in your home. This process helps save energy costs and increase comfort levels.

Tempered vacuum glazing windows are lightweight and stronger than other window options, making them suitable for many applications, such as timber windows and doors. Plus, due to their small spacer sizes, tempered vacuum glazing is easier to handle for fitting into existing frames.

As opposed to traditional double glazing, which may lead to condensation and cold spots forming over time, vacuum-glazed glass is significantly more resistant. Furthermore, its anti-oxidation treatment will ensure its clarity lasts.

Tempered vacuum glazing stands out as an efficient energy saver. It can reduce energy bills by as much as 75% compared with ordinary double-glazing and 50% when compared with triple-glazing due to its lower thermal conductivity and thick construction.

With so many advantages of vacuum glazing, it is no surprise that its use is becoming increasingly widespread among both residential and commercial properties. This revolutionary product provides considerable energy efficiency benefits as well as better acoustic insulation in homes and offices alike.

3. Energy efficiency

As energy efficiency demands continue to increase, traditional glazing methods are no longer meeting modern expectations. Luckily, smart triple vacuum insulated glass (TVG) provides a superior thermal solution, boasting U-values far surpassing those of double-glazed units found in many modern buildings.

TVG achieves its insulating properties by creating a vacuum between two panes of toughened glass and then sealing that gap with an advanced gas. This effectively blocks out heat from outside and keeps it inside, resulting in superior insulation without bulky frame materials or adding weight.

Vacuous glazing offers excellent thermal performance and is also known for providing outstanding acoustic protection. This innovative technology reduces noise transmission between living spaces and outside environments and minimizes outside noise intrusion into your home, thus improving comfort levels while creating a relaxing atmosphere in which to live your daily life.

LandGlass developed and patented vacuum glazing as an energy efficiency enhancement using solar PV modules. This technique increases energy efficiency further by turning solar energy into usable electricity that can be stored in an on-site battery and used as an alternative power source. Not only does this approach reduce building energy use, but it also cuts greenhouse gases that contribute to global warming.

Vacuum glazing (TVG) has long been used in various building applications and research has been ongoing on its thermal and acoustic properties for nearly two decades – but only recently have commercial products been created that deliver all the performance advantages associated with TVG in traditional timber windows and doors.

LandGlass’ LandVac Heritage system enables timber window manufacturers to reap the benefits of an insulating glazing system while having minimal impact on historical and conservation areas. The design of LandGlass’ bespoke glass keeps classic aesthetics while improving energy efficiency by offering U values as low as 0.4W/m2K at center pane levels.

4. Environmentally friendly

Vacuum glazing holds great promise for significantly reducing carbon levels in buildings through its superior thermal properties. It combines the high thermal insulation of traditional double glazing with its slim and contemporary design for use in historic and listed properties without compromising their aesthetics, making it one of the most promising green technologies currently available.

Vacuum glazing’s insulating properties stem from its ability to eliminate air between glass panes, creating an effective thermal barrier that drastically decreases heat loss during winter and excess heat gain in summer. Furthermore, it reduces condensation on windows for improved visibility and foggier windows in general. Furthermore, vacuum glazing offers various energy-saving features, including argon gas filling, low-e coatings, and insulated frames, further making this energy-saving technology accessible and appealing.

There may be misconceptions surrounding vacuum glazing technology, but in truth, it offers numerous environmental advantages. With its insulating capabilities, low carbon emissions, and high light transmittance properties, it provides an environmentally friendly solution for both new construction and renovation projects.

The design and construction of a vacuum glazing unit are equally important to its performance. A typical system comprises two fully tempered glass substrates with low-e coatings joined together with a spacer made from materials less likely to damage glass while having reduced corrosion risks, such as aluminum or stainless steel.

Vacuum glazing uses a pump that consumes minimal electricity to operate, significantly reducing environmental impact and greenhouse gas emissions. Furthermore, low-e coatings used in vacuum glazing prevent heat loss through the glass surface, further decreasing energy consumption and greenhouse emissions.

Note, however, that edge seals of vacuum glazing units typically exhibit higher thermal conductivity than central panes due to being made out of more permeable insulating materials; this should not pose a problem, its higher conductivity being balanced out by the superior insulating performance of central panes.
