Dualstrip & Monostrip

Intumescent high pressure activation, low volume strip for door edges and frames.  Monostrip provides ½ hour and 1 hour passive fire protection. Dualstrip provides ½ hour and 1 hour passive fire and smoke protection.

During fire exposure, the amount of smoke that is contributed by the decomposing plastic sheath with Dualstrip & Monostrip is extremely small when compared with the volume of smoke from other sources. Furthermore, the small amount of smoke that is created using Dualstrip & Monostrip will rapidly decrease as the intumescent core expands.

When using Dualstrip & Monostrip the combined action of the brush seal and intumescent seal minimises the amount of smoke that can pass through the door frame gaps.
