发明名称 COMPOSITE RIGID INSULATION MATERIALS CONTAINING V-GROOVES
摘要 <p>Flat, rectangular composite insulation comprising two dissimilar insulating materials on a separate flexible backing material is described. At least one of the two dissimilar materials is rigid. V-grooves are formed in the dissimilar materials extending from the surface of the insulation opposite of the flexible backing up to, but not through the flexible backing. The V-grooving permits the rigid composite insulation to be fitted to a curved surface such as a pipe.</p>
