Application

Flexible seals provide effective perimeter sealing for fire and smoke-controlled doors, ensuring reliable containment of flame and smoke spread across a variety of demanding door assemblies.

They’re also used for glazing seals and linear gap sealing, offering versatile protection wherever moving joints or gaps require dependable, long-lasting fire and smoke resistance.

Testing

Fire resistance tested to EN 1634-1

Ambient smoke control tested to EN 1634-3

Linear joint sealing tested to EN 1366-4

Properties

At approximately 180°C, surface graphite begins to exfoliate, progressively increasing as temperature rises, expanding to at least six times its original volume for reliable protection.

Safe to handle with no PPE required, the seals are completely non-toxic, non-fibrous and dust free, using a self-extinguishing PVC binder with added fire retardants throughout.

Totally inert, the seals remain unaffected by moisture, humidity, atmospheric pollution and other common industrial or household chemical substances, ensuring long-term durability and performance.

Available seal types

Fire-only seals feature a flexible PVC nitrile topper, with graphite intumescent from 1mm to 5mm thickness and a 0.5mm three-sided topper, available in various colours and optional self-adhesive tape.

Fire and smoke seals incorporate a cold smoke fin within the same topper construction, while graphite-only intumescent seals suit non-visible applications, supplied in varied sizes with optional self-adhesive tape.
