An Ideal Construction Solution
Apart from its natural and essential aspect, rolled zinc is remarkable for its durability, excellent recyclability and the moderate amount of energy required to manufacture it.
VMZINC solutions are a pertinent choice for the construction of buildings that respect the environment. The environmental characteristics of the materials and the systems the company offers prove this. Apart from its natural and essential aspect, rolled zinc is remarkable for its durability, its excellent recyclability and the moderate amount of energy required for its manufacture. VMZINC has had life cycle analysis tests conducted on its products and publishes Environmental Product Declarations (EPD) that are available to customers constructing sustainable buildings. Several EPDs pertaining to VMZINC solutions, such as the FDES (French EPD), the BRE Environmental Profiles (British EPD) or the IBU Zertifikats (German EPD), are now available.
These analyses provide users of the company's products and systems with comprehensive, reliable and transparent information on the environmental characteristics of the material. They are also used by VMZINC as the basis for the eco-design approach it has adopted for the development of its solutions.
A durable material
Because of the capacity of zinc to protect itself when it comes into contact with the main components of the atmosphere, the rolled zinc products used in the building have a very long life span. When rolled zinc comes into contact with oxygen, water or carbon dioxide in the atmosphere, a compact coating that is adhesive and not very soluble in rain water forms on the surface of the material. This coating considerably reduces the speed at which the atmosphere's components are diffused in the zinc, and thus reduces the speed of corrosion.
The durability of rolled zinc can be affected by certain atmospheric pollutants that increase the speed of corrosion. The most aggressive of these is sulphur dioxide (SO2), which is produced essentially by industrial production sites, thermal power plants and road traffic.
Today, the average speed of corrosion of VMZINC® rolled zinc is one lrm per year. With an initial thickness of 0.7 mm and any simple calculation demonstrates that the estimated life span of rolled zinc is over a hundred years. The lifespan of rolled zinc increased over the last five years, and will continue to increase in the coming years.
VMZINC® is 100 per cent recyclable and in Europe, 95 per cent is recovered during demolition or renovation work. Used rolled zinc is re-used in different areas of application.
