Applications:
These sandwich panels are mostly used for industrial purpose, these are very light weight but can bear
very heavy load. It also reduces the heat inside the building.
With a wide range of different colors, available in cut-to-length supply and ready-to-install,
this modern building product takes a good share in a highly economic, weather-independent and fast,
modular building process.
Beside the extremely high thermal-insulation values of the polyurethane-core,the panels create
a high overall stiffness with their "composite" function and therefore support very good statically values.
Advantages
• Light weight: 10~ 14 kg/m2and hence reduced steel frameworks and system can become economical.
• Good thermal insulation, with average coefficient of thermal conductivity is 0.018 ~ 0.020 W/mk.
• Available in customized length. And in wide range of colors.
• Cold and heat resistance: Perfect temperature resistance deformation from -110º C to 120º C.
• Great energy saver and hence indispensable in air-conditioned, cooled and heated buildings.
• Virtually zero maintenance throughout life.
• Installation is convenient and Flexible; not requiring large- scale lifting devices, and thus lowering building costs.
• High intensity and large rigidity ensures suitability for weight-bearing structures and for supporting and protective structures.
• Non-water absorbent.
• Environmentally friendly. And bring down life cycle cost for any built environment.
