PAP “The Ideal Solution”

PAP manufactures continuous sandwich-type panels with polyurethane (PUR) or polyisocyanurate (PIR) core injected between two steel plates.

The refrigeration panel is intented for constructing cold storage and agroalimentary premises by placing vertical and ceiling panels.

It can also be used for climate controlled premises or conditioned sites, both for positive or negative temperature. This kind of panel is available in smooth, striated or micro-striated finish.

The refrigeration panel is rectified at the end of the production line, where it is milled to guarantee very small assembly tolerances and optimum thermal insulation.

Besides, roof and wall panels can be used for enclosure every type of construction sites and warehouses, adding the possibility of choosing striated, or micro-striated facing finishes.


Vertical panels are longitudinally asambled, using a male-female system produced in a continuous production line shaper.



PIR                                                  PUR


  • Density: 40 +/-3Kg/m.
  • Thermal conductivity: 0,023 W/m.K




PUR and PIR components present an excellent insulation performance, they are highly effective and lightweight. They offer an excellent thermal conductivity, high resistance to weight, combined with versatility of production.


They are closed-cell insulation, which are injected between metal plates sealed during the production process. The result is a self-supporting panel, which insulation capcity barely changes over time.


The conditions for use are in accordance with existing regulations, and in particular are ready for application of the EN 14509 standard, relating to technical and mechanical resistance. The normal temperature range varies from -40ºC to +40ºC
