The future of new energy-saving glass, building materials market will be popular
With increasing the degree of building energy efficiency policies, building standards and standardized management to improve the level of the glass industry, technology, energy-saving glass, safety glass and green glass building will shine in the future, play an increasingly large effect.
Low-E glass and insulating glass, also known as multi-coated glass, with a maximum daylight transmittance and reflectance minimum. Allows 80% of visible light into the room to be absorbed by the object, but also to more than 90% of the long-wave radiation by indoor objects remain in the room, greatly improving the energy efficiency. At the same time can have a choice of transfer solar energy, most of the heat radiation to pass into the interior, the heating and building insulation can play a role in energy conservation. ILE compared to glass andpub stools glass IMF, in the heat conduction control, the same principle, but superior in reducing heat penetration.. Another Low-E glass and multi-functional glass for different spectrum of sunlight through the selective and able to consider out ultraviolet radiation, prevent indoor furniture, pictures, artwork, etc. to fade due to ultraviolet radiation, but also absorb some visible light, play an anti-glare the role.

In addition, there is a coated glass can play in the summer to prevent solar radiation and thermal radiation outside the role, the main winter indoor thermal radiation from the blocking role in the performance with low-E glass, heat-reflective glass on the basis of taking into account the performance, while retaining the original Low-E film's premise, the other by changing the film thickness appropriate to reduce the sunlight, especially in the near-infrared transmittance, reflectance and improve the absorption of sunlight, radiation is low, shading coefficient.
More energy-efficient thermal glass has its own advantages, but also have shortcomings. Use must be based on the geographical, climatic characteristics, building orientation, economic level and the level of consumption, according to local conditions to optimize the selection. Such as building high-rise or relatively abundant solar radiation toward the construction site should be used with heat-absorbing glass, insulated glass with full functionality, but also on the interior light will not cause much impact; cold and cold climates, should use low-E glass and multi-coated glass, insulating glass to full function, reduce indoor heating load; in winter hot summer areas, should use anti-radiation glass, to give full play to advantages of glass thermal insulation to reduce indoor air-conditioning load in summer.
If the construction of low or no solar radiation and parts of the building towards the use of heat-absorbing glass, heat insulation effect not only obvious, but the impact of indoor lighting, increase the lighting costs; cold and cold climates usepub chairs anti-radiation glass, you can not effectively use solar energy, will increase heating costs; hot regions in summer and winter, use low-E glass and multi-coated glass, will result in room temperature, resulting in air conditioning costs. Also coated glass although there is some energy-saving effect, but it is a form of hollow glass.
Heat-absorbing glass or anti-radiation glass and insulating glass Low-E glass to form a best match. Solar radiation is absorbed into a heat-absorbing glass, heat, hit into a long-wave radiation, the radiation, long wave radiation reflected by low-E glass, isolated and can not enter the room. In southern China, the hot region, the outer layer of glass in insulating glass coating heat-reflective film, coated Low-E glass inner membrane, not only the radiation of solar radiation on the glass reflect heat out, and heat insulating glass, clear glass, the heat transfer capability weakened, to improve the indoor thermal environment, reduce air conditioning load has a very significant role.
Should note: The above energy-saving glass expensive than many ordinary monolithic glass. One insulating glass per square meter increased by about 40 to 80, a vacuum glass 200 per square meter, an increase of about $ 400 per square meter of hollow glass coating increase of about 100 to 300. However, energy-saving glass is very significant energy savings, cost-effective. Selection should take full account of long-term use and the resulting economic effects of energy conservation, should not result in the price factor, the other. Various energy-saving effect of glass structure are different.
In recent years, with construction to multi-layer, high-rise building development and construction management to enhance standardization, safety glass has begun by the State's attention.
In 2003 the National Development and Reform Commission, Ministry of Construction, State Administration of Quality Supervision, Inspection and Quarantine, State Administration for Industry jointly issued the "Building safety glass regulations," thebar table notice. Clearly pointed out: the glass as building materials need to be part of the 11 must use safety glass. Including more than 7 layers 7 layers and buildings outside the window, an area larger than 1.5 square meters of window glass or glass-bottom surface is less than 500mm from the end fitting of windows and so on.
. Single semi-tempered glass, single glass does not belong in the wire safety glass areas. Notice from the production of safety glass, testing, use and building design, management, construction, supervision, inspection and other aspects of regulatory requirements and proposed a series of specific measures.
