Vacuum Insulated Glazing in Energy Efficient Buildings
December 14, 2018
However, Dr Saim Memon, a Senior Lecturer in Electrical Engineering at London South Bank University, says it’s one thing having a triple vacuum glazing technology and another thing to persuade the mass market to invest in this technology. The primary concern is the tendency for some gas molecules remaining in the cavity to react when exposed to sunlight and/or under extreme climate conditions for longer time periods due to the production of carbon monoxide inside the cavity that degrades the vacuum layer affecting U value.
It is obvious that triple vacuum glazing is exposed to sunlight and thus must be designed to withstand different climates and temperatures to avoid degradation of the vacuum. Further research is required to investigate and improve the durability and duty cycle of the triple vacuum glazing with the use of non-evaporable getters, that absorb gases outgassed from the internal glass surfaces in the cavity provide long-term stability of vacuum pressure of TVIG, and cost-effective hermetic edge sealing materials.
