Sandwich PU Roof Panels

Sandwich Panels, Metal-faced polyurethane sandwich panels are the system of choice today for large industrial buildings, refrigerated warehouses, office blocks, exhibition halls, fair pavilions, schools, and sports halls. Polyurethane sandwich panels come complete with specially formed tongue-and-groove joints ensuring a perfect fit and maximum integrity, Assembly is fast, easy, and cost-effective. As a result, these thin, relatively lightweight sandwich panels can safely bridge wide spans.

Manufacturing Process

The top and bottom coil (sheet metal) are clamped onto the plants unwinding unit and fed into the machine. In the first step, “corona system” cleans both reverse sides of the sheet metal using high frequency to remove greases and dirt and to guarantee the best possible subsequent full spread adhesion between foam and sheet metal. Thereafter the protective films are rolled onto outside of both metal sheets. The sheets are then brought together, the bottom sheet is foamed by the swinging foam head and the top sheet is mechanically steadied. Immediately after that, the panel is fed into the heated drying tunnel where the foam expands to its full volume, binds to the sheets and transforms both sheets to one robust, shear resistant composite structural panel. After leaving the tunnel the panels are cut according to your specification using flying saw/cutter.

These pre-fabricated elements consist of an inner insulation core between two colour-coated steel sheet layers. They are used in facades, partition walls and ceilings. They are eco-friendly and can be used for a range of applications, including food industry and cleanrooms.

Reduce Your Building's Energy Costs

• Cost-effective construction
• Significant savings in heating costs
• Reduced CO2 emissions
• Reduces construction cost

Energy Efficiency

With 80 mm thick sandwich panels with polyurethane rigid foam, the U value is 0.297 W/(mK). In comparison, a solid wall with 24 cm thick masonry and 2 cm plaster walls has a U value of 1.85 W/(mK). Rigid polyurethane foam combines excellent thermal insulation properties with good mechanical strength, making it an outstanding construction material that does not rot, mold- resistant, odourless and non-toxic for all conceivable applications, the foam is resistant to the chemicals typically used in construction and is compatible with most solvent-containing adhesives, paints and wood preservatives. Polyurethane rigid foam is extremely durable and can be installed easily and securely, ensuring cost-effective, efficient construction.
