Effective Fire and Smoke Containment
This SS seal is a sodium silicate intumescent strip that rapidly expands when exposed to extreme heat, creating a secure barrier between spaces. This rapid reaction delays the spread of fire, providing valuable additional time for evacuation. It ensures compliance with UK building regulations and fire safety standards including BS 476: Part 22 and BS EN 1634-1, delivering trusted, verified performance.
The integrated brush seal enhances smoke containment by preventing smoke leakage around doors. This dual-action design is essential to limit the risk of smoke inhalation, increasing occupant safety and building protection. For 60 minute fire doors, the SS brush seal can be installed alongside plain Lorient intumescent strips (LP1504 fire seal), and a drop down door bottom seal for all round door protection.
Versatile and Practical Installation
With self-adhesive backing, this Lorient brush seal is straightforward and quick to install. Simply cut to length, remove the adhesive backing, and firmly press into place within the routed groove. This quick installation method reduces labour costs and minimises disruption on site. No pinning is required and seals can be butt jointed together to achieve the required length.
Available in multiple practical colours—black, dark or light brown, white, and grey—the seals can match or contrast with door frames, and suit a range of interior design styles. Suitable for use with single or double leaf doors, these seals offer versatile applications across many commercial settings, including schools, hospitals, and hospitality venues.
Select the right width of seal as noted in the door’s fire test evidence, and choose a finish to match existing fire door ironmongery. Other coloured and woodgrain finishes are available as a special order, subject to minimum order quantities.
Durable and Reliable Protection
Constructed from robust, high-quality thermoplastic materials, Lorient SS seals withstand frequent use without deterioration. The durability of these seals means they remain effective even under heavy traffic conditions. Whether installed alongside Batwing perimeter seals or by themselves, they provide lasting reliability, reducing long-term maintenance and ongoing replacement costs.
The Lorient SS range is engineered to perform consistently over time, providing continuous fire and smoke protection. Trusted by industry professionals, the seals meet rigorous quality expectations, ensuring critical fire compartmentation standards are maintained at all times. Include as part of your fire door maintenance checklist and replace as necessary when damaged, with a like-for-like seal.
