Vacuum Glass – What are the benefits

Vacuum glazing has a number of benefits that can improve the efficiency and performance of the windows in a period property. Benefits include:

• Fully tempered. Vacuum glazing is a fully tempered vacuum insulated glass. It retains the safety features of tempered glass against impact and the surface stress of any position in our tempered vacuum insulated glass exceeds 90MPa.
• Energy Savings. The thermal insulation performance is 2 to 4 times better than insulated glass due to its’ high vacuum interspace that eliminates any gas heat transfer. By using high-performance Low-E coating, it also considerably suppresses radiation heat transfer and reduces the U-value of Heritage to 0.4 W/(m2K).

• Longevity. The life expectancy of our vacuum glass exceeds 25 years. The flexible edge sealing materials avoid the sealing failure caused by the brittle edge sealing material. With the assistance of built-in high-efficiency getters, our vacuum glass can sustain its superior performance against harsh environments and material ageing for many years.
• Eliminates internal condensation. The high vacuum interspace effectively eliminates the dew condensation phenomenon, while the outstanding thermal insulation performance ensures interior glass surface free of condensation even when the outdoor temperature falls to -40℃. Please see this article regarding all forms of condensation on vacuum Insulation glass.
• Noise reduction. The high vacuum interspace of vacuum glass effectively blocks sound transmission. For every 5dB of noise increase, the effect on auditory experiences differs by 3 to 4 times. The weighted sound insulation measurement indicates that an outdoor noise level of 75dB, can be reduced by 41dB, while the typical reduction by regular laminated glass is only 29dB. It has a remarkable soundproofing effect against medium and low frequency noise such as traffic and construction noise.
• Flexibility. Factors such as geographical location, elevation, and installation angle do not affect the performance. Thanks to the high vacuum interspace, there is no thermal expansion or contraction even if the elevation of the location where it’s used is significantly different from where it’s manufactured. The heat transfer coefficient of our vacuum glass remains constant regardless of whether it’s mounted horizontally or with an angle, making it suitable for energy efficient roofing or slope installation.
