Architects using zinc wall claddings and roof coverings not only profit from the durable advantages of zinc but also create astonishing aesthetics on a building.
Aesthetics, durability and many other benefits
The deformability, the low specific weight and the availability of zinc prove that no concessions have to be made when choosing a durable material.
Product Range
For modern building materials, there is a wide product range and an extensive range of material colors an architect can choose from. Next to the bright-rolled standard material, two specific pre-weathered types are developed to meet architects’ designs. NedZink’s mineral grey colored type NEO has a matte, subtle brushed surface and the its NOIR has an anthracite black color. In addition, three specific zinc color nuances are available. These distinctive colors have a unique appearance by using pigments in the variants of blue, red and green.
Zinc lasts a long time and needs no maintenance. At the end of its service life, the material is collected and reused completely. Not only by means of re-melting for zinc dipping and galvanizing processes, but also re-used after disassembling for instance panel systems on a façade.
Easy Installation
Zinc cladding systems are easy to install, because the chosen type of cladding is especially developed for quick manufacturing and assembly. For example, the panel system has a range of sizes to choose from. Pre-fabrication and simple assembly are time effective. A range of additional profiles contributes to the aesthetic value of the façade.
Façade Systems
Due to the variety of façade systems, it is easy to make a selection. The traditional standing seam system is mainly known in Europe for roof coverings, but has certainly also proved itself as a façade cladding in recent decades. The system is suitable for prefabrication, and the simple assembly makes it easy to provide a façade with a zinc outer shell. This standing seam façade cladding is not only durable, but an aesthetically pleasing eye-catcher.
In addition to the traditional standing seam system, various façade systems have been developed that offer the architect the opportunity to make a suitable choice in line with his design. Interlocking and flatlock panels are popular as façade cladding because of their appearance and easy installation.
Interlocking Panel System
The interlocking panel in particular creates a special appearance due to the shadow gap (reveal) between the panels. The dimensions of the panels and joints are variable, as are the lengths of the panels.
The characteristic of this panel is a tongue-and-groove system with concealed fasteners. It can be installed both vertically and horizontally or even a combination. The system has a series of corresponding profiles that ensure the view is straightforward and in harmony with the rest of the façade parts. The system lets architects implement their designs for most building shapes by using this system.
Zinc
Zinc is one of the most reliable metals that has been used as a building material for centuries. This includes zinc gutters, rainwater drainage systems, roof coverings and wall claddings. With a life span of 75-plus years, zinc is not only an aesthetic choice but nowadays also a sustainable choice. In addition to a long service life, more than 95% is collected and recycled again after use. It therefore answers the circular economy. There are few building materials whose overall environmental balance is as positive as for zinc.
When covering a roof or façade, you want to be sure that the material used is durable, has a beautiful appearance and, above all, lasts long and is maintenance free. Zinc has these advantages. If you compare the natural product with other metals, you even come up with seven advantages.
