Q.) Does the insulation lose R-value over time?

A.) No. Greenix Panels contain a polyurethane foam formulation that stabilizes at a relatively high R-value (about R-7 per inch of thickness) once it is placed in a building’s wall, floor, or ceiling system. The R-value of a fully cured polyurethane panel is about two-and-half times higher than that of a fiberglass-insulated stud wall.
