Saint-Gobain Introduces 4mm COOL-LITE SKN 176 II Solar Control Glass

Saint-Gobain continues to evolve its COOL-LITE SKN 176 II series solar control products.  The COOL-LITE SKN 176 II recently introduced to the market has come out with the addition of a 4mm option within the product range. This product is developed primarily for both high-end commercial and residential construction applications.

Like the COOL-LITE SKN 176 II 6mm counterpart, the 4mm product outperforms any other Saint-Gobain double silver coated glass available, combining a 70% light transmittance and 0.37 G-Value which blocks out 63% of solar heat. The product offers an excellent 1.89 solar selectivity and a thermal insulation performance of 1.0W/m²•K.  

Adrian Adams, Saint-Gobain’s Market Manager said, “The exceptional specification of the product allows more natural light to enter a building while reducing both indoor solar gain and heat loss. This not only improves well-being through a more pleasant working environment but also reduces energy assumption on heating and air conditioning, keeping in line with the concept for sustainable building design.

Glass with “Anti-fingerprint” Coating

As we all know, finger touches will leave unwanted fingerprints on ordinary glass. Now, IZOVAC Technologies has developed an anti-fingerprint coating that can be applied on glass to prevent fingerprints being left on the surface. The anti-fingerprint coating creates a layer of hydrophobic material with a water contact angle greater than 110º, effectively preventing grease from sticking to the surface.  The coating also allows easy removal of dust and dirt from the glass surface.

In addition, the anti-fingerprint coating has superior long-term durability in resisting chemical and mechanical wear. The anti-fingerprint coating deposition can be applied in combination with anti-reflective coating deposition as well. This coating has wide range of applications in industries including architectural glasses, commercial displays, and screens for smart phones.

German Scientists Invented Glass Partition Break Sensor System

According to a news media overseas, scientists of a German research institute has recently invented a glass partition break sensor system to be used primarily on architectural applications such as glass partition, screen partition, and glass curtain wall, detecting cracks as a glass break alarm system.

In recent years, architectural glass materials explode quite often, causing serious security risk and unnecessary losses to businesses and families. The break sensor is developed for glass partition and curtain wall installations and commonly mounted directly on glass products. Once the system detects a crack on the glass, the alarm will be triggered to call for immediate inspection by the building maintenance or glass partition manufacturer so that proper measurements can be taken and potential loss will be mitigated.

The announcement has been questioned by many professionals in terms of whether the break sensor can provide warning in a timely manner. Will the sensor give service team enough lead time to fix the problem?  Is the sensor more decorative than functional?  Only facts can answer these questions.  Massive scientific experiments have proven that the alarm will be triggered once a crack of 5mm or more is detected on the glass. The development of the glass partition break sensor is successful.

At present, the glass partition break sensor technology is not yet mature and still far from gaining popularity. However, this emerging product has brought good news to both glass partition and architectural glass curtain wall industries.

Large-size Curved Infrared Glass Is Made in China for The First Time

China Building Materials Academy has recently developed the large-size curved infrared glass product and successfully applied the new product in the new shared aperture photodetection system.  China, for the first time, has the ability to manufacture large-size curved infrared glass domestically, a breakthrough in this field.

Infrared materials are the leading indicators of the development of IR technology.  The properties of the materials directly determine the accuracy and performance of the IR instruments. The application of IR technology has expanded from military related to security and surveillance, remote sensing survey, DAS, and other fields. Large-size curved infrared glass preparative technology is considered to be one of the most advanced technologies in IR industry. The difficulties in hydroxy purging, glass forming, and formation of large size curved products have held back the development and equipment of some new shared aperture photodetection systems. 

During the “Twelfth Five-year Plan”, by focusing on the in depth research and development of the full array of the process technologies, including IR glass’ ingredients, melting, forming, and surface coating technologies, the R&D team of China Building Materials Academy successively tackled the key technical problems in IR glass vacuum melting technology, glass ingredients engineering, large size curved glass formation, and bubble canopy coating.  The new products feature multi-spectral penetration, excellent light transmission and mechanical strength, simple manufacturing process, and low production costs.

PPG Industries Partners with Walker Glass to Debut Bird-Safe Glass with Low-E Coating（Architectural Glass and Functional Glass, Vol. 6）

PPG Industries recently announced that in a joint effort with Walker Glass Co., Ltd., they have successfully developed a new bird-friendly glass with high-performance solar control and low-emissivity coating.

There is a large number of birds get killed every year by colliding with glass because of its transparency, reflectivity, and other factors that can create the illusion of safe passage. Aviprotek is a technology based on the studies conducted by American Bird Conservancy to reduce bird collisions by eliminating their visual illusions.

Walker Glass with Aviprotek patterns can be manufactured with PPG’s Solarban 60 or Solarban 70XL Low-E architectural glass. Aviprotek patterns on the first surface of Solarban double-pane low-e windows are proven to reduce bird injury and mortality by providing contrasting patterns that birds can see while in flight.

US Scientists Developed New Glass with a Regular Molecular Pattern

Until recently, glass has always been considered to have a non-crystal, haphazard, and disorganized molecular structure. However, by accident, researchers from the University of Chicago have created a new type of glass with a regular molecular pattern. The research team claimed that they developed the glass by vaporizing organic molecules in a regulated vacuum environment.

Researchers said that it was discovered when they were observing through a spectroscopic ellipsometer and analyzing the interaction of a beam of laser light with the material. Unexpected molecular orientation appeared in the material. Based on the discovery, they created the new glass by depositing a vapor of organic molecules, layer by layer onto a surface. 

The process is highly temperature dependent. The temperature has to be within the narrow range to successfully solidify the glass. Change of temperature will affect the molecule order. Further researches are needed as the change of the molecules will generate significant impact on the optical properties of the glass.

It is believed that the new glass will help the future development of solar cell, LED, optical fiber and many other products.

Japan has Developed New Super-strong Glass for Lighter and Thinner Cellular Phones

Recently, scientists in Japan revealed that they had created a new form of super-strong glass based on aluminum oxide. Test results indicate that the hardness of this new oxide glass has exceeded cast iron and copper. It’s even stronger than stainless steel. It may be used to make cellphone screens, allowing cellphone to be thinner and lighter. In addition, automobile windshield, building windows and many more applications could be benefited. 

As Project leader, Professor Atsunobu Masuno of the University of Tokyo said, "We are looking for ways to mass produce this new material. We believe the technology is expected to be commercialized in 5 years.”Scientists combined alumina oxide with another metal oxide - tantalum oxide in a process known as “aerodynamic levitation” technique.The new material had also undergone Vickers hardness test (by pressing the pyramidal diamond indenter into the material). The test result indicated that the new material could resist a pressure of 9.1GPa, while in comparison, the HVs are 0.7-1GPa for stainless steel and 3.9GPa for high-carbon steel.
