What is a PIR Panel?

Use these composite steel panels for improving heat and sound insulation

Our previous blog referred to PIR composite panels which are insulated steel panels.  One of customers has read our blog and asked what PIR acronym means.

PIR is an abbreviation for Polyisocyanurate, which is a thermoset plastic typically produced as a foam and used as rigid thermal insulation. PIR composite panels are typically made from foam and used as rigid thermal insulation sandwiched between the steel panels. Its thermal conductivity has a typical value of 0.16 BTU*in/hr*ft2*°F (0.023 W/(mK)).

Composite insulated panels can be used for fabrication of steel buildings. The panels are prefabricated PIR sandwich panels which are manufactured with corrosion-protected, corrugated steel facings bonded to a core of PIR foam and used extensively as roofing insulation and vertical walls (e.g. for warehousing, factories, office buildings etc.).
