Insulation and Cover Boards


ENRGY 3 CGF is a rigid roof insulation board composed of a closed-cell polyisocyanurate foam core bonded inline to an inorganic coated glass facer on each side. ENRGY 3 CGF is the right choice for systems that require improved resistance to mold growth (no cellulose content). Its smooth coated surface performs well in self-adhered systems and provides efficient-adhesive application in fully-adhered single ply systems.
