PUF / PIR Slabs & Pipe Sections Comparision

PUF materials are suitable for temperature range between -110°C to -160°C. PIR Slabs & Pipe Sections are suitable for use between -150°C to -180°C. It has low thermal conductivity value of maximum 0.021 w/mk at 10°C. It is not easily ignitable and has negligible water permeability. It is suitable for cold / chilled pipelines, building roof & wall insulation, equipment insulation and horton sphere insulation. PIR is suitable for LNG pipe insulation.


Ease of application

Resistant to almost all solvents, PUF / PIR is compatible with cold applied adhesives, sealants and vapour-barrier mastics. PUF / PIR is available in boards, pipe sections, radiused and beveled lags, with or without factory laminated facings.
