What is Vacuum Glazing?


Vacuum glazing is an emerging technology that uses a vacuum between two glass panes to enhance their insulation properties and reduce noise levels in your home. The actual Interesting Info about HaanGlas vacuum glazing.

Vacuum glazing stands out from traditional double-glazed units as extremely thin and lightweight. However, there may be certain restrictions regarding order size or scale that must be taken into consideration when ordering this new technology.


Vacuum glazing is an innovative building material that uses vacuum instead of inert gases to insulate glass panes and reduce gaseous conduction and convection between panes for low energy loss between sheets of glass. This creates an energy gap between them that does not increase condensation rates between panes of glass.

A vacuum in the glass cavity reduces heat transfer, significantly improving the thermal performance of standard double-glazed units and making them suitable for period homes and Listed buildings. This benefit can greatly benefit owners of period properties or historical landmarks.

The vacuum-insulated glass features an extremely slim profile that makes retrofitting into timber frames without needing planning permission more accessible and potentially saves thousands in the process. Plus, its classic aesthetic makes for much better restoration projects!


Vacuum glazing can reduce noise levels by up to 50 percent while acting as insulation, helping prevent heat loss and saving on heating costs.

Thick windows can have a dramatic impact on their ability to reduce sound. Thicker materials are better at blocking unwanted noise, making it harder to penetrate your space.

Lower frequencies can be particularly hard to block. Therefore, when selecting windows with an STC rating of over 50, these should provide optimal blocking performance.

Soundproofing glass can be expensive, so select the appropriate material and size. Begin by evaluating how much noise needs to be reduced before selecting your material of choice.

Energy efficiency

Vacuum glazing is an efficient way of keeping your home warm, making it the ideal choice for passive house builds that aim to minimize energy use while minimizing environmental impact – typically through reduced consumption of fossil fuels throughout the lifetime of a structure.

The unit’s design is of great significance regarding vacuum glazing’s success. Unlike inert gases, the vacuum creates high pressure that pulls glass panes together – so micro-spacers or support pillars must be included to stop these panes from bending or touching each other.

The design of vacuum-glazed units involves an intricate set of compromises involving decreasing mechanical stresses associated with support pillars (resulting in more and larger ones) while simultaneously reducing heat transport through them ( requiring fewer, smaller ones). Furthermore, glass sheets must be rigidly adhered to limit lateral movement at all costs.


When replacing windows, appearance should always be taken into consideration. So, naturally, you want to ensure that the new glass looks pleasing – after all, this is something you’ll have to live with for some time!

Vacuum glazing can help achieve this objective as its two panes of glass have such small gaps that it appears like single-glazed windows. This makes vacuum glazing ideal for heritage projects where planning officers may require renovating original windows to appear as close to the original designs.

Insulated windows also help keep your home warmer in winter by retaining more heat than standard double or triple-glazed windows, helping reduce energy bills and heating bills while making you more comfortable all year.
