US Classification:
428215, 428220, 428218, 264 463, 264145, 528 85
Abstract:
A prefabricated cover board has a high-density polymer or predominantly polymer material core layer having a density between 6 lbs/ftand 25 lbs/ft. A prefabricated roofing panel composite includes the cover board and an insulation board that has a low-density polymer or predominantly polymer material foam core layer having a density less than 6 lbs/ft. The cover board may have a waterproofing membrane forming the top major surface of the cover board. When making the roofing panel composite, the low-density foam core layer of the insulation board may be formed with the high-density core layer of the cover board being currently or subsequently formed over and bonded to a top major surface of the low-density foam core layer in the same operation or preformed insulation boards may be fed into a production line with the high-density core layer of the cover board being formed over and bonded to top major surfaces of the low-density foam core layers of the insulation boards.

US Classification:
428218, 4283159, 4283044, 428138, 4283184, 264 41
Abstract:
A method includes dispensing a first polymer or predominantly polymer material foam precursor and allowing the precursor to rise and at least partially set to form a foam core layer for an insulation board, the foam core layer having a first density. The method further comprises dispensing a second polymer or predominantly polymer material foam precursor and allowing the second precursor to rise and set to form a core layer for a cover board, the core layer for the cover board having a second density greater than the first density. The second foam precursor may include polyisocyanurate. The method may also include feeding facer materials over the precursors to form facers on the core layers. Such insulation boards and cover boards may be cut to length and installed on a roof.
