The production of polyurethane rigid foam sandwich panels has become a fundamental tool for high performance building systems.
Although the processability between PIR and PUR panels is similar but with certain differentiating nuances, such as processing temperatures, higher in the case of PIR panels, or the use of adhesives to improve the adhesion between the sheet and the foam, in the case of PIR panels, although more and more PUR panels producers are also using an adhesive in certain panels to guarantee the adhesion between the sheet and the foam, the field of application of PUR/ PIR sandwich panels is very similar, and they can be used for:
External enclosure: facades and roofs.
Compartmentalisation of interior spaces: fire sectors, partitions, food processing rooms, clean rooms, cold rooms, etc...
Advantages of PUR/PIR sandwich panels
The advantages of PUR / PIR sandwich panels is what makes these insulation panels even more attractive for health, safety and environment:
Thermal insulation: It is one of the thermal insulation products with the lowest thermal conductivity coefficient. It guarantees the absence of thermal bridges thanks to the homogeneity of the insulation at all points of the panel. The assembly also minimises thermal bridges thanks to the joints, normally tongue and groove, between panels. Reduced insulation thickness thanks to the low thermal conductivity coefficient of the polyurethane foam.
Optimisation of usable space, since a minimum thickness is required to achieve a maximum thermal insulation level.
Virtually no water absorption due to the closed cell structure of the polymer, which makes them waterproof.
Mechanical properties that give the panels great rigidity and low weight, which facilitates and economises transport, handling, installation and structural sizing. Ease of machining and cutting.
Reaction to fire performance which makes PUR/PIR sandwich panels fire safe.
PUR/PIR sandwich panels are a prefabricated product, sustainable in their manufacture and very light for transport to the construction site. The construction of a building, both residential and industrial, with polyurethane sandwich panels generates very little waste which makes the building process more sustainable. It is recyclable: the metal sheet is melted and the polyurethane is recycled using three techniques; mechanical recycling, chemical recycling or incineration with energy recovery. The insulating capacity of polyurethane sandwich panels helps to reduce energy consumption.
