Wood simulating shingle
Abstract
Abstract A SHINGLE IS DESCRIBED WHICH SIMULATES A WOOD SHAKE SHINGLE AND HAS THE INCOMPRESSIBILITY AND INSULATION PROPERTIES OF CONVENTIONAL WOOD SHAKE SHINGLES. THE SHINGLE INCLUDES AN OUTER METAL SHELL DEFINED BY A RECTANGULAR BODY SECTION OF METAL HAVING DOWNWARDLY DEPENDING WEDGE-SHAPED SIDE WALLS AND A RECTANGULARLY SHAPED END WALL. A PAD OF A GENERALLY NONCOMPRESSIBLE MATERIAL, SUCH AS A CLOSED CELL POLYURETHANE RIGID FOAM FILLS SUBSTANTIALLY THE FULL CAVITY DEFINED BY THE SHELL. THE PAD OF MATERIAL EXTENDS BETWEEN THE UNDERNEATH SURFACE OF THE BODY SECTION OF THE SHELL AND THE ROOF BASE TO WHICH THE SHINGLE IS SECURED SO AS TO SUPPORT THE BODY SECTION AND PREVENT CONCENTRATED LOADS FROM BENDING THE SAME. THE SHINGLE INCLUDES AT ITS SIDES AND ENDS STRUCTURE FOR INTERLOCKING THE SAME WITH SIMILAR SHINGLES TO PROVIDE A SHINGLE ROOF ARRANGEMENT. THE INTERLOCKING STRUCTURE AT THE SIDES OF THE SHINGLES IS DESIGNED TO PERMIT LATERAL SHIFTING OF THE SHINGLE RELATIVE TO SHINGLES LATERALLY ADJACENT THERETO, AND THE PAD HAS A CONFIGURATION PERMITTING SUCH ADJUSTABILITY.
