In people's traditional impressions, glass is usually flat, and more often used for doors, windows, curtain walls, etc. With the continuous enrichment of creative design, architectural glass products have also been greatly enriched, not only with glass homes, sanitary ware, but also with glass exterior walls. Such glass exterior materials are U-glass. U-shaped glass is also known as grooved glass because of its U-shaped feature.

From the plane to the profile, the appearance of U-shaped glass not only enriches the variety of architectural glass, but also broadens the means of architectural expression. As a kind of glass profile, U-glass is used by modern designers because of its remarkable waste-disposing characteristics, beautiful appearance characteristics and changing structural features. It has become a new type of wall material for dressing modern buildings, and thus has revised the tradition. Grayish image of a building facade.

Glass profiles

The main use of broken glass as a raw material, through the firing process similar to the float glass production process, U-shaped glass formed into a glass profile.

The U-shaped glass formed by using a specific device is an embossed glass with two rib sides. The transparent light is opaque, which makes the light soft and has a privacy protection function and a unique decorative effect. Its bending strength, sound insulation and moisturizing properties are superior to those of flat glass. Not only do they have the basic functions required for building glass, their bearing capacity exceeds that of tempered glass with the same thickness and the same length, and it is also a true new wall material.

According to Mi Jiahua, general manager of Yunnan New Wall Glass Co., Ltd., currently there are three companies producing U-shaped glass profiles in the world, including two in Germany and one in Yunnan Jiahua Company.

In fact, the Yunnan Jiahua company's production line was also originally from Germany. According to statistics, the introduction of U-glass technology resulted from the recommendation made by Chinese Prime Minister Cole when he visited China in the 1980s. In response to the requirements of the times, Yunnan Jiahua Company introduced and constructed a U-glass production line in the mid-1990s.

The appearance of U-glass in China has ended the history that domestic glass used as a door and window material and cannot be used as a wall material. It also fills the void of U-glass in China and Asia. With the participation of Mi Jiahua, the standards for U-glass products and design applications were completed.

Decorative new wall material

The appearance of U-shaped glass has enriched the choice of wall materials for modern buildings, changed the image of traditional exterior walls with a grey tone as the main tone, and replaced it with a beautiful and rich steel structure with varying rhythm rhythm and U-glass. Modern building image.

As a new type of maintenance and partition wall material, compared with the 24 cm brick wall, U-glass has reduced its self-weight by 89% and can increase the effective area by 80%. The thermal conductivity coefficient of a single plate glass having a thickness of 6 mm is 6.69 W/m2·k, the thermal conductivity coefficient of a single layer of U-glass is 4.95 W/m2·k, and the double layer is 2.39 W/m2·k. German transparent poly The carbonic acid ester is made into a honeycomb bar filled in the U-shaped glass cavity, so that the heat transfer coefficient of the U-shaped glass can reach 0.8-0.5 W/m2. The kU-type glass also has a good sound insulation capability.

Building energy efficiency is mainly achieved by improving the insulation and heat insulation properties of walls, doors and windows. Experts believe that by taking appropriate measures, U-glass insulation, thermal insulation and other properties can fully meet the building energy requirements. Like flat glass, U-glass can also be coated on the inner surface to further enhance its thermal insulation properties. Including how to temper and integrate with photovoltaic energy, etc., has become a new space to increase the added value of U-glass.

The appearance of U-shaped glass not only enriched the architectural glass products, but also enriched the choice of building wall materials, changed the image of the traditional building exterior with the main tone of gray, and replaced it with a beautiful and rich modern rhythm and rhythm. Architectural image.

As an interior wall partition material, U-glass can provide a fantastic visual beauty. As an exterior wall maintenance material, U-shaped glass brings the modern beauty of the entire building.

14,000 buildings

From the Beijing Airport to the Beijing Olympic Games News Center to the Shanghai World Expo Chile Pavilion, there are more than 14,000 U-glass buildings used in the Yunnan Jiahua Company.

Up to now, U-glass has been widely used in buildings, warehouses, office buildings, hotels, airports, railway stations, stadiums, and residential buildings, etc., for building and partition walls, Frankfurt Airport in Germany, Shaw Arts Center in the United States, and Seoul in South Korea. Universities, Dubai Cleveland, etc. are typical representatives. As a new type of wall material, U-glass has greatly enriched the creative expression of architectural designers, making modern buildings more beautiful and full of rhythm and beauty.

"Building materials are the language of architecture." The proportion of building materials in modern buildings is getting lighter, and large-span, large-space buildings are emerging. The permeability of modern architecture requires more and more, and the dynamic and rhythm is the architect's creative pursuit. U-type glass with its high material strength,? The advantages of good optical performance, thermal insulation performance, unique decorative effects and 9 kinds of free combination methods are favored by modern architects. Famous architect from the Netherlands, Ville Ariel? (WielArets) earlier began using U-glass as an exterior wall, and U-glass applications have become popular around the world.

From the Beijing Airport to the Beijing Olympic Games News Center to the Shanghai World Expo Chile Pavilion, there are more than 14,000 U-glass buildings used in the Yunnan Jiahua Company. The fourth channel of CCTV not long ago used U-glass as a typical project to implement the “Regulations on the Development of New Wall Materials in Yunnan Province” and praised the U-glass of Yunnan Jiahua Company for designers to achieve a wavy “crystal glass”. "Creative, let the Chile Pavilion shine at the Expo.

After more than ten years of reinvention, the technology level and product quality of U-glass in Yunnan's Jiahua Company are comparable to those of German products. German customers are seeking to go far to the Chinese market to purchase Yunnan Jiahua's products and sell them to the local market. The matter is no longer news. The U.S. glass of the Yunnan Jiahua Company has appeared in the developed markets of the United States, Canada, and Japan. U-shaped glass has been well demonstrated as a new type of wall material by being used in more than 14,000 buildings.
