Icynene Classic Ultra is a one-and-done innovation that eliminates the requirement for an ignition barrier in residential unvented attic applications. This ultra-low VOC insulation is a superior and more cost effective alternative to sucrose-based products due to its superior adhesion and cohesion, ability to help shorten construction schedules and reduce material costs. In collaboration with the ICC Evaluation Service (ICC-ES) and an ICC-ES accredited fire consultant, testing shows that a fire in an unvented attic assembly, equipped with Icynene Classic Ultra, is extinguished in less than a minute. The ultra-low VOC formula allows for re-entry 1 hour and re-occupancy after 2 hours of active ventilation (at 10 ACH) following installation and is GREENGUARD Gold certified.
