InsulBase®

InsulBase Polyiso Insulation

InsulBase Polyiso is a rigid insulation panel composed of closed cell polyisocyanurate foam core bonded during the manufacturing process to glass reinforced felt (GRF). ReadyFlash® Technology is a standard feature of InsulBase Polyiso that allows the contractor to manipulate flash-off times by choosing which side of the insulation to apply membrane adhesives. ReadyFlash features dark GRF on one side of the insulation board and light GRF on the other. Utilizing the sun's energy, the dark facer accelerates adhesive flash-off while the light facer slows it down.
