FIREFLY HP is a high-pressure intumescent sealant designed for sealing openings around penetrating services in fire-rated construction. As temperatures rise under fire conditions, the sealant expands to form a pressure seal, closing gaps around services and penetration interfaces.
Used across a wide range of penetration sealing applications, FIREFLY HP forms part of assessed systems incorporating FIREFLYBatt, FIREFLYMortar and FIREFLY FR Multi-Service Block. Its versatility extends across individual, grouped and mixed-service penetrations in both wall and floor applications.
Available in 400 mL and 600 mL sausages.
