Fernocryl

FernoCryl®

FernoCryl is an intumescent acoustic sealant developed to seal linear joints and service gaps in compartment walls and penetration seals. Activation takes place at approx. 180°C when the sealant will expand, forming a durable char preventing the passage of fire and smoke for periods up to 240 minutes (EI240).
