Update on the nationwide PIR board shortage

pir-factoryIn Ludwigshafen, Germany on Monday 17th October there was an explosion at a chemical manufacturing plant. The plant manufactured a large percentage of one of the key chemical ingredients for the creation of PIR boards for well-known industry names. Unfortunately this tragic accident claimed the lives of two firefighters, and the resulting factory shut down initiated a shortage of PIR boards across Europe.

After several months of supply being back to regular levels, two companies who make the chemical MDI, which is critical in the production of PIR boards, have both suffered serious manufacturing failures so the industry as a whole is unable to meet supply requirements once again. We can appreciate the frustration this must cause so in order to prevent delays or disappointment please contact us before placing any orders. You could take a look at our range of multifoil insulation or insulation slabs as a PIR alternative.
