Long-Lasting Benefits of Vacuum Double Glazing in 2025
When properly fitted into existing frames, VIG windows can improve energy efficiency up to 45% while also maintaining their original look and character.
Vacuum insulated glazing (VIG) is an energy efficient double glazing option that boasts increased energy savings. Consisting of two panes of glass separated by a vacuum gap to reduce heat transfer, VIG also looks better than traditional double-glazing and makes an ideal addition to period properties featuring original wooden windows.
VIG employs a hard molten seal that won't break down like rubber seals do in traditional units and has an expected lifetime of over 50 years. Furthermore, this perimeter seal offers greater resilience against weathering and wind-borne debris.
Improved energy efficiency
Vacuum glazing provides superior insulation while having a much slimmer profile than traditional double or triple glazing systems, as well as reduced maintenance requirements compared to regular windows. As a result, it makes vacuum glazing ideal for historic buildings where preservation must co-exist with performance demands.
Traditional double glazing consists of two glass panes separated by an air or noble gas such as argon-filled cavity that reduces heat transfer and improves energy efficiency, but still allows some thermal bridging through gaps.
HaanGlas VIG Windows retrofitting glass provides an effective solution by employing an absorber that traps and removes gas molecules that leak out, impacting insulation properties of existing windows. When properly fitted into existing frames, VIG windows can improve energy efficiency up to 45% while also maintaining their original look and character.
Reduced heat loss
Vacuum glazing differs from traditional double or triple glazing in that there is no air or inert gas between panes of glass; thus reducing heat loss and improving insulation significantly, making it one of the most cost-effective choices for energy-efficient homes. Plus, its slim design means it fits easily into older timber frames without altering their original appearance!
HaanGlas VIG Windows' retrofit glass into existing window frames in London conservation areas and listed buildings to improve insulation and lower energy costs, helping preserve their historical aesthetic while simultaneously increasing efficiency.
Though vacuum glazing initially costs more than double glazing, its long lifespan and durable perimeter seal make it a worthwhile investment for homeowners.
Reduced condensation
Vacuum glazing features a gap of less than one millimetre between glass panes, making it much thinner than standard double glazing. The space can either be left empty or filled with an inert gas such as argon; its denser density gives this technique greater insulating effects and gives vacuum glazing an insulating quality.
condensation build-up inside window panes is also avoided by keeping cold surfaces at the right temperature; otherwise moisture cannot evaporate from them properly and leads to black mould or corrosion of window frames.
To combat this, manufacturers incorporate a getter into their manufacturing process to absorb any residual gases or contaminants that might leak into the vacuum space and ensure that its insulating effect will continue over time.
Aesthetically pleasing
Vacuum glazing provides superior thermal and acoustic insulation without impacting the aesthetics of heritage buildings. Thanks to its ultra-thin profile, it can be retrofitted seamlessly into traditional timber windows and doors for increased energy efficiency while maintaining their traditional appearance.
vacuum double glazing differs from traditional double glazing in that its panes are separated by an air gap and utilizes a spacer bar filled with inert or noble gas (usually argon), which has 30 percent less thermal conductivity than air and thus results in an improved U-value.
Air gaps reduce heat loss further while improving durability of units, eliminating external seals that might otherwise require replacement and saving both time and money during installation. In addition, their absence allows insulating glass manufactured at lower heights to better withstand altitude variations that might impact them negatively.
Cost-effective
Vacuum-glass offers superior thermal insulation, enhanced soundproofing and longer lifespan compared to traditional double glazing for new construction and renovation projects. Furthermore, it's eco-friendly with substantial energy savings and sustainability advantages.
Conventional double glazing units (DGUs) use air or noble gas to insulate their cavities between glass panes; vacuum glass uses an extremely tight vacuum gap of just 0.3mm instead. This significantly decreases heat loss and allows it to achieve lower U-values than regular double or triple glazing - leading to significant energy savings and lowering heating costs for homeowners as well as increased acoustic performance - especially beneficial in London where it helps mute city noise levels. HaanGlas VIG Windows enable homeowners to install vacuum glass seamlessly into frames designed for single glazing without creating disruption - saving them considerable hassle while improving acoustic performance significantly while existing frames that were designed for single glazing with minimal disruption for installation without alteration!
