Icynene’s portfolio of spray foam insulation includes Classic Max, an open-cell, low-VOC foam that allows for re-entry and re-occupancy four hours after installation—with active ventilation. Classic Max also is an ignition-barrier–free product that the Canadian manufacturer says can smother an attic fire in less than a minute. Classic Plus is a high R-value open-cell spray foam that achieves R-22 in 2x6 wall assemblies. The product also meets prerequisites and may contribute toward points for new-construction LEED certification.
