StoneLite® Composite Wall Panels

StoneLite® panels are composite wall panels made up of a thin natural stone veneer reinforced with an aluminum honeycomb backing. The stone veneer can be almost any stone including granite, marble, limestone, slate and sandstone.

Combining the aerospace technology of aluminum honeycomb with the timeless beauty of natural granite, marble and limestone, StoneLite® can be used for a wide variety of applications including those typically considered weight or cost-prohibitive. They have been used extensively in exterior, interior, renovation, elevator, and specialty applications.
About StoneLite® Panels image

About StoneLite® Panels

StoneLite® weighs only 3.3 lbs./sq. ft. (16 kg/sq. m) about the same as 1/4-inch (6 mm) thick glass, which is approximately 80% less weight than solid stone. This weight savings alone provides huge savings in installation labor, structural requirements, and installing time.

Tough, durable StoneLite® panels offer fantastic impact resistance and flexural strength provided by our patented manufacturing process. They can resist up to 60 times more impact than solid 3 cm thick granite. These panels can be flexed making them ideal for seismic locations. Our aluminum honeycomb-reinforced panels keep the beauty of natural stone and eliminate its fragile, brittle properties.

StoneLite® is impervious to water penetration, even with open structured stones such as travertine, Indiana limestone and French limestone. The fiber-reinforced epoxy skin, directly behind the stone, provides a waterproof barrier, thereby eliminating the need for a secondary layer of protection.

StoneLite® has been subjected to, and has passed numerous severe structural tests following accelerated aging and large-scale fire tests. Minimal strength loss was experienced following freeze-thaw cycling while immersed in a 4 pH sulfuric acid solution. Resisting large missile impact and 1,342 repetitions of simulated dynamic hurricane loading are testimonials to the strength of this lightweight natural stone panel.

Marble image


Marble is an excellent choice for interior applications, however only certain stones can be used on exterior applications. Dark marble will normally fade in sunlight and almost all marble will loose a polished finish over time. If you are concerned with durability, graffiti, or staining, we recommend you select a granite.
Granite image


Granite is an excellent choice for all applications, especially if you are concerned with durability, graffiti, or staining.StoneLite® panels can be produced from almost any stone provided that slabs are available in large enough sizes.
Limestone image


Limestone is usually more economical than granite and some marble, but if you are concerned with durability, graffiti, or staining, we recommend you select a granite.
