Stone Rainscreen Sub-framing
Preferred Partners: 

Material Overview:

Stone rainscreens are increasingly more popular for drained and back-ventilated rainscreen applications. Using various quarries, stone panels are installed with either concealed systems or with exposed clip systems.  All types of stones in varying sizes and finishes are being used to create dramatic, high performance rainscreen facades.  Anchor systems can be engineered to ensure the appropriate pullout strengths once stone thickness are determined.

Design Considerations:

The local quarry is best at determining what size panels and thicknesses are available.  ECO Cladding can then work to develop the appropriate attachment system for the project.

Cornell University Health Center - Ithaca, NY

ECO Cladding is pleased to have partnered with the designers at Ithaca-based Chiang O'Brien Architects for a full renovation of an existing health services building with a complementary addition designed to alleviate growth challenges at Cornell University. The renovated Cornell Health building is anchored with a heavy bluestone base and transitions into a curtain wall of transparent glass with natural stone rainscreen panels that imitate the coloration of the native bluestone foundation but expand the scale and scope.

ECO Cladding’s Alpha Vci.41 System was ideal for the installation complexities of this renovation project, including the need to overcome the variable stone thicknesses inherent to 2” thick natural stone. The Vci.41 System provided a subframing solution that could address c.i. requirements and also support the weight of 2” thick natural stone panels.

Center for Missouri Studies - Columbia MO

The State Historical Society of Missouri has a new home in the newly completed Center for Missouri Studies in Columbia, Missouri, designed by Multistudio

The center incorporates materials from different areas in Missouri including a dimensional limestone facade which is attached with ECO Cladding's Alpha Vci.41 concealed subframing system. The design reflects Missouri’s geological characteristics. Installation of the limestone cladding was performed by Heitkamp Masonry of St. Louis.

Integrating local and recyclable products, the Historical Society wanted a structure that would last for a hundred years. Many efficiencies have been built into the design as they look to achieve LEED Gold status from the USGBC. ECO Cladding's Continuous Insulation (c.i.) compliant Alpha Wall Brackets contribute to both the energy efficiency and sustainability of the building's envelope.

The scalabillity of ECO Cladding's Alpha bracket systems enable an engineered solution that can accomodate the unique properties of limestone as well as any other type of cladding panels.

Temple U Science Education Center – Philadelphia, PA

The Temple University Science Education and Research Center, designed by USA Architects, utilized a Stone Rainscreen with an ECO Cladding subframing attachment system. This remarkable building serves as to model the growing trend in using natural stone for modern rainscreen applications and ECO Cladding's variety of concealed or exposed subframing systems provide the engineered peace-of-mind necessary for natural stone rainscreen assemblies.
