WebWhen we talk about polyurethane insulation we are referring to a group of insulation materials based on PUR (polyurethane) or PIR (polyisocyanurate). The closed cell structure and high crosslinking density of PUR and PIR gives it the characteristics of good heat stability, high compressive strength and excellent insulation properties. WebJM Open Cell 450 (OC-450) Spray Polyurethane Foam insulation is a two-component, low-density, E84 Class A rated, nonstructural insulation system designed for interior commercial, residential and industrial applications. JM OC-450 is 100% water blown.
