Vacuum glazing is an innovative fenestration technology that outshone traditional double or triple glazing when it comes to thermal and acoustic insulation. Additionally, it was developed specifically to be retrofitted into historic buildings while meeting stringent aesthetic criteria set by architectural heritage standards.
Operating like conventional double glazing, vacuum double glazing works by creating a vacuum between two toughened glass panes rather than filling any gaps between them with gas. Micro-support pillars evenly distributed among them create and sustain this vacuum effect.
Double glazing
Vacuum insulated glazing (VIG), also referred to as vacuum double glazing or vacuum-insulated glass (VIG), is an efficient way of improving insulation without altering visual aesthetics. With exceptional thermal performance that reduces energy loss and bills significantly over time, it proves cost-effective over time.
Effective insulation requires eliminating gaps between panes of toughened glass, creating a vacuum-like environment to act as an effective insulator and reduce heat transfer by up to 80%. Further improving thermal performance are microscopic spacers which separate panes under atmospheric pressure without diminishing window clarity.
HaanGlas VIG windows are increasingly being installed into older and listed properties in London due to their slim profile, which allows it to fit within existing frames without needing major modifications, thereby maintaining their historic character while providing superior acoustic insulation to reduce noise pollution from busy streets.
Insulating glass
Vacuum glazing has become an increasingly popular retrofit choice in traditional window frames of heritage buildings and conservation areas, thanks to its high thermal efficiency and lack of an internal double-glazing spacer bar that preserves slim profiles while maintaining aesthetics of single-glazed windows. As such, vacuum glazing provides the ideal solution for maintaining historic character while at the same time modernizing them.
Vacuum glazing differs from traditional double glazing in that instead of filling the space between glass panes with argon gas, it creates an air gap and evacuates it using advanced technology, leaving only vacuum behind as insulation similar to what thermos flasks do.
In order to prevent atmospheric forces from forcing two glass panes together, microscopic pillars are installed between them – almost invisible but kept secure with advanced hermetic composite edge seals – in order to minimise heat transfer and acoustic transmission, as well as minimise heat transfer and acoustic transmission – providing two to four times more insulation than double glazing and six to ten times more than single glazing products.
Retrofitting glass
Vacuum glazing is an innovative technology that elevates insulation to new heights. By replacing air or inert gas between glass sheets with an hermetically sealed vacuum gap, it dramatically decreases heat transfer and energy consumption, as well as daylight enhancement and noise reduction – perfect for renovating historic buildings!
Glass’ hermetic gap is held together by microscopic pillars that are invisible to the naked eye, yet provide load strength for temperature differentials and remain structurally sound against temperature variances. Furthermore, this technology features a flexible edge seal to alleviate stress-related issues, such as bending of entire glazing unit and potential seal failure caused by atmospheric pressure differentials.
Vacuum glazed windows are constructed using two layers of toughened glass that meet British Standards for thermally toughened safety glass. Furthermore, vacuum glazed windows are more sturdy than double-glazed glass and less likely to shatter into dangerous pieces, making them safer in high-risk areas such as prisons. Furthermore, vacuum glazed windows offer homeowners and property developers looking for energy efficiency improvements an alternative without replacing current windows with replacements.
HaanGlas
Vacuum Insulated Glazing (VIG) is an innovative glass technology that offers superior insulation. Utilizing a vacuum layer between two panes of glass, VIG reduces heat transfer between them to lower energy costs and carbon emissions while being more durable and impact resistant than double-glazed windows; making vacuum insulating glass an excellent choice for residential, commercial, and industrial buildings alike.
HaanGlas VIG can be installed into historical properties to improve energy efficiency without altering their architectural integrity, as its slim profile enables retrofitting into existing sash windows – an ideal solution for period properties.
VIG can be more costly than traditional glass options; however, its environmental friendliness helps reduce a building’s carbon footprint and lead to significant energy savings over time. With less maintenance required for VIG products resulting in further environmental sustainability goals.
