### Critical Thickness of Insulation - Critical Radius

Critical Thickness of Insulation – Critical Radius. In a plane wall the area perpendicular to the direction of heat flow adding more insulation to a wall always decreases heat transfer. The thicker the insulation, the lower the heat transfer rate. This is due to the fact the outer surface have always the same area.. But in cylindrical and spherical coordinates, the addition of insulation ...
