What does PIR mean in UNCLASSIFIED

PIR is a closed-cell foam insulation that consists primarily of polyurethane and small amounts of other chemicals. Most commonly these are benzene diisocyanate (BDI) and triazine based compounds.

Compared to other types of insulation such as fiberglass or spray foam, PIR offers superior thermal performance due to its low thermal conductivity. It is also better at sealing air leaks than other materials due to its tight cell structure which prevents airflow through cavities in the material.

PIR can be used in many different applications including walls, ceilings, floors and roofs for both residential and commercial buildings. It can also be used for HVAC ductwork and in industrial settings to help prevent hot spots from forming on pipes or equipment.

You can purchase PIR insulation from hardware stores as well as online retailers like Amazon or eBay. If you need larger quantities then you may need to go through an industrial supplier who specializes in bulk materials like this type of foam insulation.

Yes! In addition to the benefits mentioned above, another notable property of this material is that it meets stringent European fire safety standards which means it won't emit toxic gases if exposed to flames during a fire emergency situation. So even though it may cost more than other forms of insulation upfront, its added fire safety features make it worth considering when choosing an insulator for your project.
