Building Envelopes For The 22nd Century

SlenderWall Architectural Cladding Panels. SlenderWall is a high performance, thermal and fire code compliant, ASTM E119 fire tested, architectural precast composite modular cladding system. Reduce structural costs and on-site trades with the only envelope system that combines the proven technologies: architectural precast concrete, PVA fiber and welded wire reinforcing, stainless-steel fasteners and ready for drywall heavy gauge G90 galvanized steel studs, to create a single efficient solution for new construction or re-cladding. Have a question? Contact Us.

SlenderWall is designed to be lightweight (66% less than traditional architectural precast), reducing foundation and superstructure requirements and reducing shipping and installation costs. The exterior precast concrete cladding and integrated stud system is isolated from the structural stresses associated with wind loading (tested to 226mph), steel frame movement, expansion and contraction, and seismic shock. Engineered to last into the 22nd Century and beyond. Read "A Case for SlenderWall" - 6 case studies on a wide-range of market applications.

technical intro 1

Use standard panels for economy or customized solutions to meet your design imagination.

For maximum economy design SlenderWall panels to be uniform in shape, size and finish, but never think architectural precast panels are bland. The designs, applications, and finishes you can engineer into SlenderWall are wide ranging. Unique shapes, window configurations, cast-in materials, and exotic looks that mimic much more expensive finishes are all possible.
