LIGHTWEIGHT STONE GLASS®
Patent Pending
LIGHTWEIGHT STONE GLASS® is lightweight shatterproof safety panel in stone material laminated with glass sheets by FFPROCESS®
High process technology and high new performant raw materials, are essential to have this new excellent panel
Some marbles, granites or stones, gauged in thin thicknesses, gain transparence, outstanding colors and natural drawings. Rare and precious onyxes can be used too, even if they have natural cracks. The decorative thin layer of stone laminated to the glass, combines the beauty of the first to the excellent mechanical characteristics of the last, all in one single new product, the LIGHTWEIGHT STONE GLASS®.
Technical characteristics
To understand the technical characteristic of LIGHTWEIGHT STONE GLASS® panel is necessary understand the technical characteristic of a common stone-glass panel: the specific gravity of glass is the same as the stone (2700 kg/cu m), so, the glass has only the function of trasparent layer support to thin layer of stone. The weight, in kilograms, of a common stone-glass panel is calculated with the following formula: surface area of the stone-glass panel (example 1.00 sqm) multiplied by the thickness of the stone-glass panel (example 0.016 m), multiplied by their specific weight 2700 kg/cu m (1.00 x 0.016 x 2700 = kg 43.2).
So, the weight of a common stone-glass panel of 16 mm thickness is 43,2 kg/sqm. Well, attention please, the weight of LIGHTWEIGHT STONE GLASS® panel of same thickness 16 mm, is only 32 kg/sqm. This weight reduction is possible thanks to new patent stratification of composite layers of stone and glass that reduce the specific gravity from 2700 kg/cu m to 2000 kg/cu m.
LIGHTWEIGHT STONE GLASS® is lightweight shatterproof safety panel, flexible and elastic to shock.
LIGHTWEIGHT STONE GLASS® panel stratification, vacuum with heat cycle and in absence of resins, is the maximum quality guarantee in terms of duration and for security purpose (in case of shocks). Our working process guarantees:
• durability of the transparent laminated glass with light transmission rate (except stone) more than 85% ;
• UV resistance of 98.5% .
Usable types of stone
It is possible to use any stone, once being checked in advance for the level of transparency, after gauging to thin thickness.
Usable types of glass
Extra-clear glasses.
Dimension
LIGHTWEIGHT STONE GLASS® panels maximum sizes are mm 2800 x 1500.
Thickness
16 mm (12mm composite layers by extra light glass and super pvb + 4mm stone).
Cutting
LIGHTWEIGHT STONE GLASS® panels can be cut by traditional machinery using normal tools of glass industry or marble industry;
Types of application
Interiors: shelves, work plans, internal walls, enlightened walls, enlightened false ceiling, desk tops, tables, door claddings, vanity tops, etc.
LIGHTWEIGHT STONE GLASS® panels may be used also outdoor, in properly framed metalwork.
Example of two LIGHTWEIGHT STONE GLASS® panels in pink marble (neon backlighting system);
dimensions of each one: mm 2200 x 950 x 16
weight of each one: kgs 67
FACTORY PRODUCTION CONTROL to guarantee the mechanical characteristics of LIGHTWEIGHT STONE GLASS® panels:
• Flexural strength under concentrated load, before and after ageing cycles;
• Rupture energy, before and after ageing cycles;
• Monoaxial Traction, before and after ageing cycles;
• Other specific quality tests for any specific final application
