For interior and exterior applications
In 2013, Zahner began offering a sophisticated zinc patina, a subtle variant surface which evokes the artistic styles of centuries past. Baroque Zinc™ is a reference to the historic detail used to produce drama, exuberance, and grandeur. Like the art and architecture from the historic baroque period, the zinc material is an expressive material which conveys an emotive response.
Baroque Zinc™ is produced using Zahner’s strong background in science and comprehensive understanding of chemical compounds derived from CEO/President L. William Zahner's practical studies and subsequent books on of architectural metals.
The patinated metal can be seen most recently on the new Max Brenner Flagship Stores by Gensler Architects. Carolina Tombolesi of Gensler described the new patina as “covered with chocolate morsels, alluding to the factory concept for the love of making chocolate.”
Patinated Zinc Wall Panel Systems
Baroque Zinc™ is cultivated on a base layer of raw zinc sourced from carefully selected pieces by Jarden Zinc Products, the makers of zinc coated pennies. The material can be produced at thicknesses from 3mm to 0.5mm, at sizes up to 43"x160”.
The material is available in sheet form, but any forming or fabrication processes altering to the metal surface should be performed prior to application of the patina.
Zinc Aging and Weathering
Zinc is one of the few materials designed for long-term projects. Whereas an aluminum facade is only specified to last a few decades, zinc is a noble metal that can last upwards of 120 years.
In environments with prolonged direct moisture, the outward facing of the zinc may be susceptible to white-gray areas and streaks, with our without a patinated surface. Typical conditions will darken the patina over time. However, in moisture-heavy regions, the material will lighten over time. The combined result is that the patina will grow over time. Zinc is a sophisticated material that ages with integrity not unlike the elegance of a copper patina.
For best performance, the back face of the zinc material should not be exposed to moisture. If exposed to moisture attack from the reverse side, it may result in perforation/disintegration of the surface over time. This is why the back facing of zinc is sometimes covered with plastisol or a similar coating.
Specifying Baroque Zinc™
Baroque Zinc™ is a preweathered zinc material featuring an artistically applied custom patina developed by Zahner. Patinas should not be confused with paint. A patina is a mineralized oxide on metal that is self-limiting (rust, for instance, is not self-limiting because it will continue to eat through a surface). A patina is a reaction to the elements that in turn provides a protective barrier from the elements.
At Zahner, we believe in the details. We believe in the surface of a building, and in the innate beauty that good architecture brings to its surroundings. Our philosophy is rooted the notion that an architectural surface should hold its beauty for years to come. For this reason, we offer a complete range of zinc patinas which vary as dramatically as the structures of the buildings to which they are applied.
