Project Description

Materials Laboratory needed for certification testing of PIR Rigid cold insulation,
PIR (Polyisocynurate) foam segments are high-quality insulating materials with excellent properties
and are supplied in pipe sections and slabs. Other types available on request. Standard densities are
50 (PIR), other densities are also available.
PIR are used extensively on equipment and piping operating at lower temperatures in power stations,
marine vessels, petrochemical plants, oil refineries etc.
