The advantages of terracotta panels compared with other curtain wall materials

Terracotta Panel1. Colors
Stone:Single color which is unable to satisfied the requirements of the designer. What’s more, either marble or granite, the surface of it will fade and discoloration over time.
Metal Panel:Although the color can be adjusted in accordance with requirements of the designer, the metal panel has poor durability and metal texture is too strong. It can not accomplished architect’s dream. It is also easy to deform and discolorate in the windy and rainy weather.
Terracotta Panel: Terracotta panel can visualize architect design and integrate architecture and art with its colorful and unique art. Terracotta panel is made from natural clay, combining natural clay color, fulling of unique art. Clay is colorful, sand color, brown, red soil, sand gray, pearl white, pink, silver, iron gray and other colors. The terracotta panels are also favored by many architects with the varies of different surfaces: natural plain surface, groove surface, glazed surface etc.In addition, terracotta panels have good physical performance, such as high hardness, no deformation, never fade, and minimized color difference.
2. Safety and shock resistance, acid and alkali resistance
Stone:It is natural items that has rich silicon oxide, aluminum oxide or calcium carbonate minerals, and all of them contain radioactive elements – chlorine.
Sheet Panel:Metal panels are feared of acid corrosion.
Terracotta Panel: The raw materials are natural clay, which do not contain any radioactive elements; after calcination in 1200 degrees kiln, a portion of mineral elements contained in the clay (aluminum oxide, silicon oxide or the like) has been completely oxidized.
3. Energy conservation
Stone:Non-renewable natural materials, and can not be recycled.
Metal Panels: Mainly use aluminum alloy, the resource of which has been almost mined up in the world. The thickness of the metal panels is limited. With its high thermal conductivity, it does not have any energy-saving effect.
Terracotta Panel: Clay is a renewable resource and can be recycled. The production determines its features of relative environmentally friendly, and low energy consumption. The hollow structure of terracotta panels and the appropriate insulation system play a very important role in energy conservation.
4. Installation
Stone:Installation of stone curtain wall is basically using back cut anchor bolt or grooved with clips to install. Both of these two methods will destroy the stone structure. Under certain conditions, when the stress release is completed, it will be broken or damaged, security performance and shock resistance are relatively low.
Metal Panel:the panel thickness is very thin. It is easily damaged and deformed by the external force, so it is with low safety performance.
Terracotta Panel: Installation problem has been considered when extrusion. Pre-made back groove is easy to mount. With up to 16-20Mpa pressure strength, safety performance and seismic resistance is far superior to stone, metal plates and other materials.
