PU/PIR metal-face sandwich panels can be manufactured with the PU/PIR reaction mix is first laid down on one metal facing. During the expansion process, rigid polyurethane foam passes through a tacky phase, which enables it to form a strong bond with the facings. The insulating effect of PU/PIR foams is much better than that of mineral wool, for example, a layer of PU/PIR ten centimeters thick has a heat transfer coefficient of around 0.25 W/m2K. A rough estimate of what this difference means in terms of energy consumption can be made based on the example of a factory building. Assuming the building has a floor area of 40X20 square meters and 10 meters high, the annual amount of heating oil saved could be roughly 3,000 litres if both the walls and the roof are insulated with PU/PIR metal-faced sandwich panels rather than panels of the same thickness based on mineral wool. Low energy consumption also results in an equivalent reduction in carbon dioxide emissions.   Industrial Construction of PUF 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. The aluminum or steel facings themselves are surface coated and can be manufactured with profiles of various depths leading to a higher load bearing. Polyurethane sandwich panels come complete with specially formed tongue-and-groove joints ensuring a fit and maximum integrity. Assembly is fast, easy and cost effective. The resultant sandwich panel has a load-bearing capability many times greater than that achieved by adding together the load-bearing capacities of the individual layers. As a result, these thin, relatively lightweight sandwich panels can safely bridge wide spans. For example, a panel just 100mm thick can easily bridge a clear span of some 6 meters.   Energy efficiency With 80mm thick sandwich panels with polyurethane rigid foam, the U value is 0.297 W/(m2 K). In comparison, a solid wall with 24cm thick masonry and 2 cm plaster walls has U value of 1.85 W/(m2 K). Rigid polyurethane foam combines excellent thermal insulation properties with good mechanical strength, making it an outstanding construction material that does not rot, mold-resistant, odorless 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 durable and can be installed easily and securely, ensuring cost-effective, efficient construction.

These panels functions well as a roof or wall panel when used in conjunction with pre-engineered buildings or conventional steel framing systems. The product features an overlapping major rib at the panel sidelap. This sandwich panel is filled with CFC free polyurethane in the core achieving good R-values and consists of exterior and interior facings of relatively thin metal sheet profiled.
