Clay tiles and floor blocks are the bridge elements of horizontal architecture. Rigid yet lightweight, they cover the spans between joists, acting as permanent formwork for concrete and as a fire shield for the load-bearing framework.
Clay is extruded through a die generating a continuous ribbon, cut to desired lengths up to 120 cm. The high perforation percentage reduces weight without compromising longitudinal flexural strength. External dovetail scoring guarantees perfect adhesion of bedding mortar or plaster.
The introduction of the steel I-beam in the late 19th century revolutionised construction. Clay blocks resting on the lower flanges created a rigid, incombustible floor. Subsequently, flat tiles were used as incombustible planking over wooden roof trusses (scempiato roof) or as lightweight covers for ventilated crawl spaces.

Physical properties
Usage environment
When cutting tiles to fit, use an angle grinder with a diamond disc. Never use percussion tools: the thin cell walls shatter. For suspended ceilings, galvanised metal wire ties are anchored through the cells every 30 cm.
