Rapid, Reliable Fire Door Protection

The Lorient intumescent-only seal provides a crucial first line of defence during fire incidents. Once exposed to heat, these fire seals quickly expand. They create an insulating barrier between spaces, restricting flames and delaying the spread of fire. This rapid expansion can transform a standard door assembly into a robust fire-resistant barrier, providing essential time for evacuation and effective emergency response.

These intumescent strips have been tested and certified to BS 476: Part 22 and BS EN 1634-1 standards. This ensures that they deliver reliable performance on both 30-minute and 60-minute rated fire doors. Select the right size to match the fire rating of your door.

For building owners and facilities managers, the seals guarantee compliance with UK fire safety regulations, offering reassurance through verified and trusted fire protection solutions. For acoustic and smoke sealing, install double or single Batwing seals with this plain fire seal. Alternatively, combined fire and smoke seals are available in the Lorient SS range. 

Quick, Simple Seal Installation

Lorient intumescent fire seals feature a practical, self-adhesive backing, designed for straightforward fitting. Cut the strips to the required lengths, remove the backing, and firmly apply them within the routed grooves in the door frame. They can be butt-jointed together to achieve different lengths or are supplied as standard in 1000mm and 2100mm lengths.

This efficient installation process saves time, reduces labour costs, and minimises disruption to building operations during fire door upgrades or new installations. It is not recommended to pin these seals, and they can be painted over once installed. Intumescent strips should sit flush with the surface and not impede the effective opening or closing of the door.

Available in several different casing finishes—including black, dark brown brown, cream, and grey—these intumescent strips blend discreetly into door assemblies, maintaining visual continuity within buildings. Special finishes and lengths are available to order so contact our team today to discuss your compliant fire door hardware needs.

Robust and Durable Construction

Manufactured with a durable PVC casing, the plain Lorient fire seals maintain their integrity and function consistently. Their robust construction ensures long-term reliability without the need for on-going maintenance, making them cost-effective over the lifecycle of the building. Make sure to check the seals are in place and intact as part of your regular door maintenance routine and replace damaged or missing door seals as required.

Capable of withstanding the stresses of daily use, Lorient intumescent seals retain their essential fire protection properties throughout the lifecycle of the fire door. Their durable nature, tested to 100,000 cycles, allows building managers to rely on their ongoing fire protection capability.
