Reliable Fire and Smoke Seals for Ultimate Protection

Lorient Finesse seals are expertly engineered using advanced intumescent materials that expand upon exposure to high heat. This rapid expansion seals gaps around doors, effectively preventing fire and smoke from spreading through buildings. Unlike fire-only seals, these comprehensive strips also incorporate an integral smoke control feature. This restricts harmful smoke ingress, significantly improving safety during emergencies. 

With Lorient Finesse fire and smoke intumescent strips, safety isn’t compromised by aesthetics; the streamlined design blends discreetly with modern, luxury interiors, complementing both door and frame. As standard, the flexible blades are clear so are perfect for projects prioritising aesthetics alongside passive fire safety. A variety of seal finishes are available on request, including black, grey, light brown, and dark brown. Contact one of the team today for help with a compliant solution for your facility.

Acoustic Seals that Improve Comfort and Privacy

Beyond fire and smoke protection, Lorient Finesse seals also deliver acoustic sealing within buildings. Tested rigorously to British and European Standards, these acoustic seals reduce unwanted noise transfer between rooms, corridors, and public spaces. This makes them essential for environments such as offices, hotels, hospitals, and educational institutions, where privacy and reduced sound transmission are crucial. 

By incorporating acoustic seals, building occupants benefit directly from quieter, more comfortable living and working conditions without additional costly acoustic treatments. For additional reduction of sound transfer, install an automatic drop seal, like the Lorient LAS8001, to seal bottom door gaps.

Easy Installation for Long-Term Compliance and Safety

Designed with ease of fitting in mind, Lorient Finesse seals slot effortlessly into pre-machined grooves, and have a heavy duty self-adhesive backing. Facility manager and installers can appreciate their simplicity; once installed, these seals require minimal attention, significantly reducing ongoing maintenance costs and downtime. 

Contractors can confidently specify these intumescent seals, knowing they'll consistently meet compliance standards and rigorous fire resistance regulations, protecting occupants and maintaining building integrity over time. Choose the right door seal based on door height, width, thickness, fire rating, and other specific requirements. Then maintain them as part of your regular fire door ironmongery maintenance routine, following manufacturer instructions.
