Stone Lamina panels are constructed using a unique, laminated, composite material structure for extreme strength, low weight, and ductility. The SL-AHP standard panel is made from 3003 aluminum alloy foil in the form of a honeycomb cell core sandwiched between two continuous layers of solid aluminum sheathing. On top of the honeycomb core is 2-5mm (0.08-0.20”) of real, natural stone veneer bonded with a special form of aviation epoxy adhesive. This epoxy was chosen for its ability to withstand 300 MPH winds, very high sheering forces, tensile forces, and a wide range of temperature extremes… all without delaminating or losing any structural integrity.

The key to the unique properties of our Composite Honeycomb Panel Technology is the design of the aluminum honeycomb cell core. Not all manufacturers of stone panels use an aluminum honeycomb core coupled with aluminum sheathing on either side. Using aluminum throughout the core allows the composite panel to achieve its incredible performance characteristics, such as its ability to sustain a large missile impact of more than 4,000 lbs/ft².

The Honeycomb core can vary in cell size and in thickness to achieve the desired strength characteristics depending on the application. Generally, exterior applications require thicker cores with larger cells than interior applications. 

Exposed edge areas are a source of potential weakness in the design as they may be susceptible to local impact or environmental damage. Edge closures are also important because they may also provide localized reinforcement, attachment points, or simply meeting aesthetic requirements. We have a number of edging solutions available depending on the application required.
