Presenting The Thin Limestone Panel System

By bonding a veneer of our distinctive natural material to an advanced honeycomb backing, a Thin Limestone Panel System offers cutting-edge possibilities for building, engineering and architecture.

An iconic building material enters a new era of design.

The unique natural character of Indiana Limestone. Now in a modular panel designed for your current building challenges.

Substantially lighter.

Thin limestone panels weigh in at 80% less than solid slabs, which translates to a vastly lighter load - on structures, labor crews, and equipment costs.

Significantly stronger.

Thin panels boast 60 times more impact-resistance than the solid slabs they are produced from. Plus, they deliver enhanced flexural strength and stand up to extreme freeze-thaw cycles.

Intelligently modular.

The predesigned panels are available in standard-sized units, don't require a complex layout, and install easily. It's an economical means for making the Indiana Limestone look a reality.

Ageless stone meets advanced performance.

Our interlocking channel system delivers installation speed.

A. Honeycomb Core

This man-made structure replicates nature’s proven geometry, resulting in a material of low density and high strength.

B. Aluminum Sheet

The honeycomb core is held tense between an aluminum sheet and fiberglass mesh for incredible rigidity and impact-resistance that remains lightweight.

C. Limestone Veneer

Our limestone is precision-cut to a thin veneer and adhered to the layered honeycomb, presenting a beautiful, natural-looking face.

D. Adhesive Bonding

Limestone veneer and fiberglass mesh become one through a bonding process that’s been thoroughly tested.

E. Factory-Attached Clip

Panels arrive on-site, ready to install.

F. Field-Attached Channel

Anchors securely to building substrate.

Unmistakable Indiana Limestone.

Reimagined with advantages for achieving new visions in design.
