Comprehensive Fire Protection and Compliance

These Lorient intumescent strips offer reliable fire protection by rapidly expanding when exposed to heat, sealing gaps around the door edges. Made from sodium silicate, these intumescent seals expand up to several times their original size, effectively preventing the passage of flames and smoke. Certified to BS EN 1634-1:2008, these seals ensure your doors meet stringent UK fire safety regulations, crucial for public buildings, commercial properties, and areas requiring reliable passive fire protection.

Choose the correct width of seal depending on the fire rating and test evidence of your doorset. Do not mix and match brands of intumescent seal - different expansion rates can cause more harm than good. The Lorient DS range includes sizes for 30, 60, 90, and 120 minute fire doors. They can also be supplied in a wide variety of finishes, and white fins, so contact our team today for guidance on a compliant fire door solution tailored to your facility or project. 

Superior Smoke and Acoustic Performance

Smoke inhalation is the primary risk in a fire emergency. The DS Lorient fire and smoke seals integrate twin fins designed to prevent the harmful passage of smoke, protecting escape routes and adjacent rooms. Tested to rigorous smoke sealing standards, they provide critical protection by sealing door perimeters effectively. When installing to the meeting stiles on double doors, fit a length of this twin blade DS seal on one leaf, and the Lorient plain intumescent-only seal on the opposite leaf.

In addition to smoke protection, the acoustic sealing properties enhance comfort and privacy. Whether in offices, schools, healthcare facilities, or hotels, Lorient DS door seals significantly reduce unwanted noise, helping maintain an environment conducive to concentration, rest, and privacy.

Quick and Easy Installation with Lasting Durability

Installation couldn't be simpler with Lorient DS fire, smoke, and acoustic door seals. Featuring heavy-duty self-adhesive backing tape, the seals can be quickly and securely applied to door frames without specialist tools. The adhesive strength provides long-term reliability, ensuring the seals remain firmly in place, even under frequent door usage.

Constructed from robust materials, this cleverly designed seal can be installed either way up. This allows for quicker installation and helps to ensure consistent fire and acoustic performance. Choose door seals suitable for the environment, users, and the door itself.

Dependable Performance for Demanding Environments

Choosing Lorient door seals means choosing reliability, compliance, and practical performance. These seals protect occupants, buildings, and assets by effectively containing fire, controlling smoke spread, and reducing noise transfer. Install compliant intumescent seals and secure lasting, robust protection for your building project or facility.
