MANUFACTURING AND ASSEMBLY OF ROOFING COMPONENTS

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...

Beschreibung
Zusammenfassung:	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.
