Exceptional Fire and Smoke Protection

The TS Lorient intumescent seals play a crucial role in passive fire protection strategies. When exposed to heat, these strips expand significantly to seal the gap around the fire door. This action prevents the spread of fire and smoke throughout the building. This intumescent action with the addition of the twin flexible fins, effectively contains hazards within a specified area and safeguards occupants and property.

Make sure to fit door seals that meet the required regulatory requirements of your facility. The TS seals have been rigorously tested to British and European standards including BS 476: Part 22 and BS EN 1634-1. Proven to withstand intense heat, the seal ensures compliance with the latest fire safety regulations, delivering reliable protection for both 30-minute and 60-minute rated fire door assemblies.

Superior Acoustic Insulation

Beyond fire protection, the Lorient TS range significantly reduces noise transmission through doors, making it ideal for applications requiring acoustic containment. Whether installed in offices, educational facilities, hospitals, or hotels, these door seals help maintain quieter, more comfortable environments. 

The acoustic performance meets BS EN ISO 10140-2 standards, ensuring users experience superior acoustic protection. The TS seal can be installed with plain fire seals or Batwing seals in the head and jamb, plus door bottom seals like the LAS8001 mortice seal or LAS8003 surface mounted drop seal.

Ease of Installation and Versatility

Installing Lorient TS fire door smoke seals is straightforward thanks to the heavy duty self-adhesive backing. Cut to length, peel off the backing, and press firmly into the pre-routed groove. They can be butt-jointed together to achieve the required length. This method allows rapid, mess-free installation, minimising downtime and labour costs during fit-outs or refurbishments - no pinning needed.

The seals' slim profile integrates discreetly into door frames without compromising aesthetics, maintaining a professional finish. Only the 4mm flexible blades should protrude from the surface of the frame, the rest should be flush. The flat body of the seal can be painted but the fins must remain paint-free, and form a continuous smoke seal around the door.

Available in standard colours including black, brown, and grey, Lorient fire and smoke seals blend well with modern and traditional premises. Special order woodgrain and other finishes are available to match your existing doors or door hardware, plus other lengths as a special order.

Essential Protection for Building Compliance

Investing in Lorient TS acoustic, smoke, and fire seals ensures your doors provide maximum safety, regulatory compliance, and acoustic comfort. Tested and certified performance combined with easy installation makes these intumescent strips an essential choice for architects, contractors, and fire safety professionals committed to building quality, safety, and functionality.
