Vacuum-insulated glass windows use transparent spacers supported by a layer of vacuum between their panes as insulation rather than air or argon for insulation purposes. Choose the best vacuum glass cost.
Tempered glass provides extra safety measures and helps protect evacuation holes from being breached due to impacts.
Hybrid IGUs with VacuMax VIG technology from Vitro Glass can be produced using various Solarban 70 solar control, low-e, and bird-friendly glazing options for optimal solar protection and bird migration control.
Heat Insulation
Vacuum Insulating Glass (VIG) windows eliminate the air gap found in traditional double-glazed windows, making them more effective at reducing heat transfer and energy loss. Furthermore, VIG offers an industry-leading R-value, helping lower energy consumption in homes and businesses and contributing to more eco-friendly practices that result in savings on bills as well as an overall healthier future.
VIGs are energy-efficient windows with the potential to reduce heat transfer six times more effectively than regular windows containing air or argon gas in between panes of glass. By replacing air with low-emissivity (low-E) coatings that absorb and reflect radiant heat instead of transmitting it directly through the glass itself, a vacuum gap is created, and thermal performance four times greater than air-filled IGUs is realized.
VIG’s vacuum gap is not empty but instead contains microscopic transparent pillars to support its vacuum layer and keep condensation at bay, thus prolonging insulation value and slowing glass breakdown over time. These unobtrusive support pillars can only be seen from the side view. These support pillars play an integral part in VIG technology as they prevent condensation formation, which reduces insulation value while slowing glass breakdown over time.
Not only are pillars effective at preventing condensation, but they also help ensure that glass remains watertight and free from moisture—essential factors in maintaining its structural integrity under harsh weather conditions, such as in airports or high-rise buildings where VIG units may be installed.
Fineo stands apart from traditional double glazing by being an easily installable solution that requires no frames yet still achieves superior acoustic and thermal insulation. By eliminating frames, Fineo can help transform historic buildings while keeping their architectural character and visual appeal. In turn, this creates a skinny profile while providing all of the insulation benefits associated with triple glazing.
Noise Reduction
Vacuum-insulated glass (VIG) offers superior insulation over traditional glazing solutions. The vacuum gap between its two panes eliminates pathways for heat transfer, decreasing energy use and emissions while providing lightweight solutions such as electric cars.
VIG increases comfort in buildings by eliminating noise pollution from outside. Thanks to its vacuum gap and tight seal of its edges against each other, VIG creates an effective barrier against external noise. This effect is especially notable at lower and middle frequencies, where other forms of glass typically lose effectiveness.
VIG windows can help reduce condensation, which is often a common problem with traditional windows. With sealed edges preventing dew-point temperatures from being reached and staying free of water droplets and moisture accumulating on its surfaces, VIG prevents harmful condensation that could otherwise pose health hazards or compromise its integrity.
VIG windows also boast the unique capability to be fitted into historic buildings without needing to alter existing frames, making them known as Heritage Windows and used in various projects worldwide. They can easily fit into existing frames to give a modern, aesthetically appealing appearance without compromising performance.
VIG is highly sensitive to pressure and impact, so its installation must be handled and completed by experienced professionals in order to avoid any loss of vacuum that could potentially compromise its performance. Furthermore, sealing it properly to remain airtight and weatherproof requires using high-quality materials as well as appropriate installation techniques for long-term success.
High Elevation Safety
Vacuum-insulating glass windows can be used in high-elevation buildings without compromising their structural integrity. Traditional insulated windows expand when transported to altitudes higher than their production locations, but vacuum-insulated glass doesn’t leave air between panes, so it doesn’t experience this expansion and, therefore, has less stress at higher altitudes.
Due to its low stress level, vacuum glass can also be more easily sealed onto other materials and structures, making it an excellent solution for steeply sloping sites.
VIG further improves structural integrity with its unique design, which employs a new interlocking technology to secure two glass panes together [28]. This eliminates rigid spacers required by conventional insulated glass units and permits soft low-e coatings to reduce radiant heat transfer through rigid spacers – thus leading to reduced insulation performance requirements and more excellent safety standards.
Traditional insulated glass requires a rigid, continuous, interlocking structure to avoid gaps between its panes. This structure introduces significant shear forces at its edges due to atmospheric pressure differences and temperature changes, leading to combined stresses exceeding its strength design value and potentially fracturing the material itself.
Fineo has developed a revolutionary, patented fusion-bonded interlocking system designed to evenly distribute shear forces over the surface of the glass, thus significantly decreasing the risk of fracture and improving insulation performance. A stainless steel thermal bridge layer placed behind a low-e coating also enhances insulation performance and helps ease edge stresses at glass edges.
Vacuum-insulated glass windows combine energy efficiency and safety features into an attractive upgrade for existing building frames. They do not require replacement and can fit most window shapes without replacing frames. They may especially prove attractive as an upgrade solution to meet BAFA (Bundesabkommen fur effiziente Gebaude) subsidy requirements for older properties built prior to energy-efficient glazing solutions being widely adopted.
Durability
VIG’s vacuum gap provides insulation against both conduction and convection heat transfer, making VIG up to 15 times more insulating than traditional double glazing and leading to energy savings and reduced carbon emissions for your home or building. This also means cost savings through reduced energy use as well as decreased emissions.
This revolutionary technology is highly durable, as it uses metal edge sealant that does not cause glass to anneal and can withstand high-temperature fluctuations. Furthermore, the glass surface is protected from scratches and corrosion using a multi-layer anti-reflective coating that helps preserve performance and appearance as long as possible.
VIG can be utilized in multiple window configurations, from monolithic Starphire Ultra-Clear glass to multi-glazed IGUs with Solarban low-e coating on surface #2 and bird-friendly patterns on surface 1. Since VIG serves as a spacer, it makes an ideal replacement for existing double-glazed windows—simply swap out its inner lite without changing frames!
VIG windows offer enhanced insulation and energy efficiency, making them the ideal choice for new construction as well as retrofitting older windows. Their lightweight construction reduces load-bearing costs, while thermal performance enables substantial savings on heating and cooling bills, contributing towards creating a sustainable built environment.
As the VIG industry evolves, its manufacturing process and product will likely improve, decreasing cost while further increasing performance—making VIG an affordable choice for residential homes, commercial buildings, and schools.
As the VIG industry develops, it should become more adept at meeting current and future codes and regulations on energy costs, noise pollution reduction, and creating a healthy built environment. VIGs are particularly suited to meeting these goals due to their lower energy consumption, which in turn reduces carbon emissions while providing significant cost savings for building owners.
