The vacuum glass for passive house, is an innovation building material that is becoming popular for passive house designers due to it's exceptional energy efficiency ratings.

Vacuum glass for passive house concept comes from the configuration with the same principles as the Dewar flask. The glass comprises two panels of glass with an evacuated space(0.15mm-0.3mm) supported by micro pillars between the two glass sheets. With a hermetic seal around the edges of the two glass sheets, a high and stable thermally insulating internal vacuum assures the insulation efficiency.

Vacuum glass is with low U-value. As we know the lower U-value the better the insulation effect. The U-value for vacuum glass is 0.4-0.6W/㎡. k, it means you can greatly increase the energy efficiency of your building without sacrificing natural light or views. Vacuum glass can reduce heat loss by up to 60%, greatly reducing the transmission of energy both inside and outside of the house.

Vacuum glass is super durable with requiring minimal maintenance. The vacuum layer crates a thermal break that prevents heat from escaping or entering the building. Vacuum glass will not decrease insulation capabilities over time, it's lifespan will last above 25 years and maintain insulating properties for decades.

Vacuum glass is high-performance soundproofing with reducing sound above 39 decibels. It able to block out noise and prevent sound transmission, helping minimize noise pollution in noisy, busy and high-traffic areas.

Vacuum glass is anti-condensation and frost-resistant. There is no condensation even the temperature will reach minus 70 degrees. So no matter how the temperature different indoors and outdoors, vacuum glass will provide excellent vision and clarity in residential and commercial buildings.

Vacuum glass is light in weight, the minimum weight is 20kgs per SQM. The glass thickness is thinner, the aluminum profile load is less. If traditional glass want to meet such high performance, the thickness for glass have to choose above 19mm which weight is 47.5kgs per SQM, then the cost for aluminum profiles and windows will increase accordingly.

The vacuum glass for passive house can help creating comfortable living environment, reducing carbon emission and contributing to sustainable development. The passive house with vacuum glass window can achieve a higher level of energy efficiency than with traditional double or triple glazing windows.

If you are looking for a glass which will provide ultimate energy efficiency, excellent vision and easy maintenance, choose vacuum glass for passive house!
