The super slim profile of vacuum insulated glass means it can be easily retrofitted into all timber windows and doors. Vacuum glass helps to maintain the original historic appearance without sacrificing thermal performance because vacuum glazing has super performance on thermal insualtion and heat preservation. If you are interested in using vacuum glazing for your window and door project, then please get in touch. We have been working with vacuum glazing for more than 18 years and have good experience of the advantages. Today, we will compare several vacuum glass on the building glass market to find out which one is the best vacuum glass for windows and doors.
ICESUN Vacuum Glass
ICESUN tempered vacuum glass is consisted by two tempered glass panes which are separated by an array of supporting pillars and welded together by glass at very low temperature . The vacuum degree between glasses is 10-4 Pa, so the thermal convection no longer exists, the heat conduction is reduced to the limit, and the Low-E layer reflects more than 95% of the infrared radiation. Therefore, the heat between the inner and outer glass plates cannot be exchanged, achieving excellent thermal insulation effect. Besides, the unique of vacuum eye technology makes the lifespan of glass visible, which allow users know the life of their windows at any time. And the maximum sound insulation of ICESUN vacuum glass can reach 46dB. What`s more, ICESUN vacuum glass has super long lifespan up to 50 years.
LandVac
LandVac is manufactured in China and its vacuum glass products also have good features in thermal and sound insulation while also retaining the strength and safety of the glass at a high level.
Spacia® STII by Pilkington/NSG.
The World`s first commercially available vacuum glazing, this product came out of research in Australia and was then patented in Japan and produced via Nippon Sheet Glass (NSG) in the 1980s. This is the first generation of vacuum glazing and while it has proven longevity, it has been surpassed in performance in recent years.
FINEO 8 by AGC.
FINEO is new to the market released in 2019. It is manufactured by AGC in Belgium. It is targeted specifically towards replacement into existing frames.
Which Vacuum glass has the best performance?
12.4mm ICESUN vacuum glass is a clear winner because it offers U-values and lifespan far exceeding LandVac, Pilkington Spacia and AGC FINEO. In fact, palm-thick ICESUN vacuum glass delivers U-values in excess of a solid brick wall, energy efficient enough to be applied in passive house and green building projects.
What`s the difference of Vacuum glass appearance?
AGC FINEO has no visible plugs on the face; however, it isn`t that simple. FINEO also has a thicker cavity, which can give a slight double reflection. ICESUN vacuum glass and LandVac has the fewest micro-spacers per square metre of glass, FINEO and Spacia® both have more than 10 times as many! And only ICESUN vacuum glass has vacuum eye which makes users easily to check the lifespan of their vacuum glass windows in virtue of its unique vacuum eye technology.
Which Vacuum glass has the longest lifespan?
Both LandVac and FINEO offer 15-year warranties and both companies give longevity of over 25 years. But ICESUN vacuum glass provides 15-year warranties and expected longevity of 50 years. It is important to consider lifespan and warranty when choosing vacuum glass for windows, and people should consider in the context of the length of time the vacuum glass has been on the market and the strength of the company offering the warranty.
For now, Vacuum glass is the most sustainable building glazing type on the market. Ordinary double or triple glazed units require Noble gases in the cavity and the creation of these gases is hugely energy intensive. What's worse, the ongoing performance is lower and as the gases escape through the semi-porous seal, the units become progressively less effective. Fortunately, the lifespan and heat insulation performance of ICESUN Vacuum glazing also far exceeds the standard industry expectation. In conclusion, the most sustainable vacuum glass is likely to be ICESUN vacuum glass because of its superior performance and the long service life. Here is a table below to compare the main aspects of vacuum glass:
