Comblanchien limestone originally formed at the bottom of an ancient, shallow tropical sea. Calcium carbonate forms and builds up around grains of sand or pieces of shells or coral, cementing them together. Over time limestone is formed. Comblanchien limestone is quarried in France. The beautiful soft tone of Comblanchien is prized for architectural stone panels. With StonePly panels the aluminum panel strengthens the limestone. In fact Stoneply panels have 60 times the impact strength of un-reinforced limestone panels.

Comblanchien limestone is a beautiful natural stone. Best suited for interior applications and for some protected exterior applications, Comblanchien limestone provides a classically attractive look. StonePly panels of Comblanchien limestone are 60x stronger than un-reinforced limestone panels and much easier to handle and attach. Comblanchien limestone has a fine, slightly grainy texture and soft warm color.
