Custom Architectural Slenderwall®

Leesburg Concrete is a licensed producer of SlenderWall®, a proprietary exterior cladding wall system with superb design flexibility. Our architectural precast concrete/steel-stud building panels offer limitless combinations of architectural precast textures, colors, shapes and finishes. In addition, it is lightweight (about 30 lbs. per square foot compared to approximately 85 lbs. for traditional heavy architectural precast), economical (reduces building foundation and structure costs, plus shipping and installation costs), and perfect for both re-cladding and new construction. The SlenderWall® panel’s exterior surface is 2 inches of reinforced high-strength architectural precast concrete separated from the steel stud by ½” air space reduces thermal transfer between the materials. The inside surface is 14-16 gauge, 6-inch galvanized steel studs spaced vertically at 2-foot centers. The architectural concrete is secured to the steel-stud frame with ThermaGuard™, a proprietary connection system utilizing insulated, stainless-steel welded Nelson® anchors. SlenderWall® has been fully tested and meets the required ASTM and AAMA standards. SlenderWall® is used for new construction, re-cladding, and renovation of large, multi-story commercial buildings.
