Understanding Fire Door Seal Technology

Intumescent and Smoke Seals – Design, Function & Compliance

Intumescent and smoke seals are a critical component of any fire door assembly. They provide both fire resistance and smoke control in accordance with UK fire safety standards.

Intumescent core: Expands rapidly when exposed to extreme heat, closing the gap between the door and the frame.

Smoke control brush or fin: Acts immediately to block cold smoke, which is often the first hazard in a fire.

Options include:

  • FD30 fire door seals – 10mm or 15mm widths
  • FD60 fire door seals – 20mm width
  • Finishes in black, brown, and white to match door furniture and accessories

Fitting guidance: Install into a routed groove on the vertical and top edges of the door or frame (not the bottom) to create a continuous protective barrier.

Compliance & suitability: Tested to BS 476 and BS EN 1634, suitable for commercial, residential, and public buildings across the UK.

Choosing the Right Seal

Fire-Only vs Fire & Smoke Seals

Fire-Only Seals: Designed to expand in a fire to block flames and hot gases, but they do not stop smoke before heat activation.

Fire & Smoke Seals: Include a brush or rubber fin for immediate smoke control, offering greater protection and often required under UK building regulations.

Pro Tip: Most UK installations specify fire & smoke seals for life safety. Fire-only seals are generally used in specialist applications where ventilation is required.

Frequently Asked Questions

Where are intumescent and smoke seals fitted?

They’re installed in a routed groove on the vertical and top edges of the fire door or frame, never the bottom.

What size should I choose for my fire door?

FD30 doors usually take 10mm or 15mm strips, while FD60 doors require 20mm.

What’s the difference between fire-only and fire & smoke seals?

Fire-only seals expand in heat to block flames but don’t stop early smoke; fire & smoke seals add a brush or fin to block smoke immediately.
