Vacuum-insulated glazing is the latest advancement in window technology. It significantly outshines traditional air or argon-insulating windows, offering comparable thermal performance as triple glazing without its thickness restrictions. Find the best vacuum glazing vs. double glazing.
VIG uses fewer materials than triple glazing, thereby reducing both the weight and thickness of glass units. This makes installation simpler in historic buildings or where slim-profile glazed units are desired.
1. Improved thermal insulation
Vacuum insulating glazing (VIG) offers superior thermal insulation compared to existing glass technologies, leading to energy savings for building owners. VIG features a lower U-value or heat transfer coefficient than comparable products and its thinner profile and lighter weight make it suitable for use in windows and doors where thermal performance is essential.
VIG’s superior thermal efficiency stems from its absence of an air gap between panes of glass, unlike traditional double-glazed windows that use air and gas mixtures as filler material, creating pathways for heat transfer via convection and conduction. By eliminating an air gap and replacing it with a vacuum instead, VIG prevents all paths for heat flow, thereby effectively stopping its transference.
VIG’s revolutionary development now makes them available for timber windows and doors that meet or surpass the energy-saving requirements of FENSA and other certification bodies. VIG can even be used in historic building timber frames to help maintain their original appearance while significantly increasing the structure’s energy efficiency.
VIG’s reduced thickness and weight make it suitable for retrofitting into existing timber windows or doors without replacing their frames. This is especially important in heritage and listed buildings where maintaining the current appearance is of the utmost importance. Furthermore, VIG is also ideal for new-build projects as it can easily fit into timber or steel frames without impacting aesthetics or functionality.
VIG’s enhanced thermal insulation keeps indoor temperatures consistent all year long while significantly reducing energy usage compared to traditional glazing systems, leading to direct cost savings for building owners as well as contributing towards creating a greener and more sustainable future.
VIG insulation panels can be easily installed between panes of glass and sealed on both sides with a special polymer known as “getters,” which evaporate at low rates at room temperature so as to prevent condensation which would compromise insulation levels, keeping windows and doors clear of dirt and moisture accumulation. Getters also help maintain clean glass surfaces.
2. Reduced noise
Vacuum insulating glazing removes the air that typically collects between panes of glass, creating thinner profiles while offering high thermal performance and enhanced light transmission – up to 8% more efficient than 36mm triple glazing units!
The resultant vacuum offers excellent acoustic insulation, significantly reducing external noise in your home. This is particularly helpful if you live near busy roads, railway lines, or airports, enabling you to enjoy peace in your own space without listening to traffic and sirens.
Vacuum glazing is particularly lightweight compared to other insulating glazing technologies, making it suitable for new builds and retrofit projects. Furthermore, it’s more energy efficient than double glazing and significantly lighter than triple glazing, thus helping keep energy costs under control.
Vacuum insulating glazing offers another key advantage: it can be combined with various coatings and interlayers to bring about aesthetic and functional improvements. For instance, it could be combined with solar coatings to increase light transmittance while simultaneously improving the sound insulation of windows and providing increased insulation against noise intrusion while adding decorative flair.
PVB interlayers can help improve the acoustic performance of windows while adding an aesthetic touch that will really bring life and charm to any property. Furthermore, various vacuum spacers are designed specifically to reduce the transmittance of soundwaves between panes of glass.
Vacuum-insulated glazing has proven more effective in terms of acoustic insulation than laminated or traditional insulating glass because it eliminates gaps between panes that allow air movement and soundwave transmission.
Fineo’s vacuum-insulated glazing can easily be integrated into any new build or renovation project and installed into existing frames for double-glazing performance, providing benefits similar to those of conventional double-glazing. This feature is particularly advantageous if you want to enhance your current window system without replacing frames altogether – and can make a significant difference in terms of acoustic insulation and comfort levels in your property.
3. Improved acoustic insulation
VIGs utilize the vacuum-insulating gap created by an absence of air or gas molecules to achieve superior acoustic insulation, significantly decreasing outside noise transmission into homes and buildings equipped with VIG. As a result, homes and buildings fitted with VIG are much quieter and more comfortable compared to those without. While VIG can be installed into all types of doors and windows, its benefits are beneficial for opening outward towards areas with heavy traffic or where noise from outdoors may enter directly through any doorways or windows that open outward towards areas with heavy traffic or areas where outside noise will enter through doorways or windows which open outward into areas with noise from outside filtering in from outdoors through doors and windows that open outward into those opening outward into high traffic or noise coming in through windows and doors which open outward into areas with large amounts of outside noise coming directly in from outside or filter in from outside sources or through doors/windows which open outward from where noise from outside noise enters through from outside will filtering in quickly from outside sources or will filter in via doors/windows/windows opening outward into areas where noise inevitably filter into homes or buildings with VIG. VIG is especially advantageous where the noise comes through or that opens outward to areas with high traffic congestion or where outside noise will filter in from outside sources, allowing outdoor noise to filter in from outside sources which allow outside noise filtering into homes or where outside sounds enter their own due to gaps that open out into areas where outdoor noise filters in through from where outside or that let in from outside; as it creates.
VIG differs significantly from traditional double or triple glazing in that its panes are spaced just 0.2-0.5 mm apart, maintaining this microscopically tight gap without conduction or convection through small cylindrical support pillars that are evenly distributed and resistant to atmospheric pressure.
This minute gap provides unrivaled thermal insulation and soundproofing compared to any gas-filled glazing solutions currently on the market, leading to dramatic savings in energy consumption, which translate into reduced home heating bills and smaller carbon footprints.
VIG windows also feature vacuum gaps to block heat transference from one side to the other, helping homeowners maintain more stable indoor temperatures and significantly reducing energy usage and costs.
VIG is thinner and lighter than traditional double or triple-glazing systems, making it easily applicable to a range of windows and an attractive option for modern energy-efficient homes and properties.
VIG windows offer more excellent form and function than traditional double or triple glazing by eliminating ugly cavities with thinner layers of glass and providing slimmer profiles, making it suitable for restoration projects and listed buildings. They have even earned themselves the name ‘Heritage Windows” due to their lightweight yet slim profiles; to discover more about them, contact us or find one near you.
4. Better aesthetics
Vacuum insulating glazing (VIG) offers an energy-efficient yet attractive window solution, thanks to an evacuated space between each pane of glass that measures just 0.3mm in width compared to 16-26mm for standard double-glazed windows. VIG makes double-glazed windows appear like single-glazing and can even be retrofitted into existing timber frames without needing replacement – an essential benefit in period properties and listed buildings where maintaining original appearances is crucial.
VIG’s low thickness and superior insulation properties enable it to be installed easily into both new construction projects and existing timber window and door frames and make it more cost-effective than other energy-efficiency solutions such as secondary glazing.
VIG is a revolutionary product with the potential to transform how we live and work, providing benefits beyond its incredible energy performance. The key to its success is combining cutting-edge technology with Vitro glass substrates to create an IGU with unrivaled thermal performance that rivals that of traditional walls.
Once upon a time, many homes were forced to choose between warmth and comfort and maintaining their historic features. With improved energy insulation methods and heating systems in place, this has changed considerably, but there remains room for further enhancement—that’s where vacuum-insulated glazing comes into play!
VIG has been designed to save energy by minimizing heat transfer between a building’s interior and exterior. It uses non-evaporable getters placed between glass panes that prevent heat penetration through them and condensation forming on condensation-prone areas of glass surfaces.
VIG can also reduce stress caused by variations in altitude, making installation possible at higher elevations than with traditional insulating glass products.
