Rigid polyurethane foam

(Type PIR)

Among the wide range of thermo-insulating materials available on the market, panels made of rigid polyurethane foam have the lowest thermal conductivity rate. In practice, it allows for using a thinner layer isolation.

We produce PIR foams in four densities:

  • S-37 kg/m3
  • S-42 kg/m3
  • S-63 kg/m3
  • S-105 kg/m3

Also on offer we have a PUR foam with lower density:

  • S-35 kg/m3

Lower foam densities are used for thermal insulation and filling polyester laminates. Densities from 42 kg/m3 to 105 kg/m3 are used with the constructions which require an increased foam hardness.



Rigid polyurethane foam

Panels made of made of rigid polyurethane foam are used:

  • to insulate: walls, floors, ceilings, flat roofs, sloping roof;
  • as a sandwich panel core;
  • in refrigerating, shipbuilding and automotive industry.

Granulate polyurethane foam is used in hard-to-reach places, where the use of panels is difficult or impossible.


Dust made of rigid polyurethane foam is used to produce, for instance, a heavy-duty clearing paste.
