Rigid Insulation Board

Polyisocyanurate or PIR orginates from a great proportion of methylene diphenyl diisocyanate, used in reaction with a polyester-derived polyol, at raised temperatures. PIR insulation boards are versatile, used efficiently for pitched and flat roofs, walls, floors, or cavity insulation. One of the main advantages actually stems from the manufacturing process as this enables their stability and strength and so instills great thermal performance results.
