- A Triumph of Modern Glass Technology
- Weight/Strength
NEOPARIES is lighter and stronger than granite and more resistant
to scratching and abrasion than marble. They are not subject to
the fissure and fracture patterns that commonly result from the
quarrying of stone. With a greater bending strength, they can
fabricated into thinner panels than natural stone.
- Easily Formed into Curved Panels
NEOPARIES can be re-formed into a wide range of convex and concave
radii panels, resulting in greater design flexibility at lower
cost than hewn stone.
- Impermeability/Minimum Maintenance
NEOPARIES is virtually impermeable and are not subject to freeze-thaw
damage, penetration by rust, mortar or other staining substances.
Moisture absorption, as a design consideration, has been eliminated.
With NEOPARIES, contaminants are easily removed during regular
building maintenance. Even graffiti can be cleaned without difficulties.
- Low Thermal Expansion
With an extremely low coefficient of expansion, NEOPARIES is not
subject to thermal cracking that can affect other cladding materials.
- Weather Resistance
NEOPARIES is significantly more resistant to acids, alkalis, oils
and other chemical substances than either marble or granite. Unlike
stone, their surface and physical properties are not degraded
even after years of exposure to environmental pollutants, including
acid rain.
