Surface Applied Intumescent Seals: Our extruded, surface-applied fire and smoke seals are engineered for improved performance and shelf life. These self-extinguishing, flame-retardant seals are formulated with a proprietary chemistry using silicone and intumescent.
Head & Jamb Intumescent Seals: Intumescent fire seals for use where smoke and draft control is not required. Mortised into wood doors or frames, or into edge strips of wood or composite door leaf. Wide range of choices tested to positive pressure standards.
Automatic Door Bottoms: Mortised and surface applied options available with intumescent material for fire protection applications.
