pietra alleggeritais one of the high-tech systems used by Ghirardi stone contractors in order to reduce the weight of the stone item. An attractive transparent effect can also be achieved using an exclusive process to make fissured materials such as onyx structurally more robust.

This excellent system means natural stone has no limits in terms of design and can be used for boat furnishings, lift coverings, aircraft, technical surfaces and numerous other interior and exterior applications.

Thanks to a process of sandwiching with other materials, the composite product is extremely robust and easy to use. The thin variable layer of onyx or any other natural stone can be made integral with various types of backing, such as aluminium honeycomb, fibreglass leather, galvanised sheet, or a thin lamina of aluminium and glass to maintain the original transparency or create a backlighting effect.

The panels can come with various types of surface finish, such as polished, lapped, brushed or antique-effect. Curved panels of any shape can also be obtained by means of special processes.

Ghirardi's technical team is directly involved in the design and calculations required for the executive project. They also provide invaluable assistance in selecting the right kind of lightened stone for the specific application.
