How is the use of rolled zinc an asset for a building designed according to the HQE approach?
It is an asset because it allows: a harmonious relationship between the building and its immediate environment (conforms to target 1): the rolled zinc products provide a wide choice of systems and a varied range of textures (natural, preweathered) and colours (lacquered). Limitation of environmental impact (conforms to target 2): the amount of energy required to produce rolled zinc products is the lowest in the non-ferrous metal market. 90% of these products are recyclable at the end of their life. A low pollution factor on the building site (conforms to target 3): fast installation of rolled zinc products, no on-site pollution and very little waste from the site. Limitation of impact related to maintenance and upkeep of the building (conforms to target 7): rolled zinc products are very durable. Protection from noise inside the building (conforms to target 9): zinc is a non-ferrous metal that does not act like a drum; its acoustic attenuation index is comparable to that of slate.
