The advantages and disadvantages of glass curtain wall

Advantages

Compared with other wall materials, glass curtain wall has its significant advantages - their light weight. Usually, the glass curtain wall own weight only has 50 kg/m2, is only 1/12 ~ 1/10 of brick wall, 1/7 of concrete precast slab wall, to reduce the weight of the high-rise building wall, reduce the basis and the main structure of the cost, and also to improve the reliability and security of the main structure.

Glass with an incomparable uniqueness for other materials , transparency, natural light through the glass into the interior, to make the indoor light enough, to create a bright environment. During the day, and don't need or reduce indoor artificial lighting, to achieve the goal of energy saving.

Usually, endothermic glass infrared absorption, reduced by 20% ~ 30% solar energy of the incident quantity, reduce into indoor heat energy, have heat preservation thermal insulation. To adopt energy saving effect excellent new coated glass - low-e coated glass (low-e glass) can make nearly 70% of the solar visible light and near infrared light through, be helpful for natural light daylighting, save lighting costs, the far infrared light has very Low radiation. From indoor and outdoor temperature object thermal radiation is difficult to through the glass radiation, can block the indoor heat radiation exchange, has good heat preservation performance. In addition, use the heat insulation aluminum, hollow glass and high quality accessories, also for glass curtain wall heat preservation performance provides a reliable guarantee.

Disadvantages

Of course, glass curtain wall also have certain limitation.

One is a large area using for the curtain wall glass, especially large area to use coated glass products, below the sunshine beamed, coated glass from different angles reflex the light that pedestrians and drivers, residents blindfold, thus forming serious light pollution.

The second is safety. Since the development and utilization of glass curtain wall, already had a few years, glass especially hollow glass quality guarantee period only 20 years, some cities,  especially in large and medium-sized cities, such as Beijing and Shanghai are the first large area use hollow glass curtain wall of the city. A large number of curtain wall glass overterm service, if its change, often cause human, material, such as resource waste, but if you don't change, the potential risk coefficient will continue to increase.

Third is to reduce noise limitations. In the design of curtain wall glass, sometimes using single chip toughened glass, such as 8 mm, 10 mm, 12 mm toughened glass, but these glass in reducing noise has no played its proper role, and now large-scale use of hollow glass especially vacuum glass, will greatly reduce the noise, also be helpful for saving energy and environmental protection.
