ABSTRACT:
A composite iso board (10) comprises a foam core (11) selected from the group consisting of polyisocyanurate and polyurethane materials and mixtures thereof; and first and second facers (12, 13), between which the foam core is sandwiched, the facers comprising a sheet selected from the group consisting of polyamides and polycarbonates. A method of reroofing a roof comprises applying composite iso boards of the present invention to a roof deck; and, applying a weather protective layer over the iso boards. A continuous method of making a composite iso board comprising the steps of feeding a first layer of facer material into a laminator (24); depositing a foamable polymer liquid onto the first layer (12); feeding a second layer of facer material (13) into the laminator above the foamable polymer liquid; allowing the polymer liquid to rise between the first and second facer materials forming polymer foam (42) of a predetermined thickness; curing the polymer foam under heat to create the iso board; cutting the iso board to desired lengths; and stacking said boards in bundles.
