Unlocking the Benefits of the DS Seal: A Multifunctional Door Seal

Let's explore some of the advantages of Lorient's DS Seal:

• Fire & Smoke Protection – In the event of a fire the DS seal will expand & seal the gaps between the fire door leaf and frame around the door, containing the spread of fire for a period of time. The fins on the seal restrict smoke movement around a building – giving people time to escape and reducing property damage.
• Acoustic Containment – Excellent acoustic performance to meet the requirements of Approved Document E. Lorient’s fin seal technology has been proven to deliver superior acoustic performance when compared to a brush type seal.
• Thermal Containment – Successfully tested for air tightness under BS 476: Pt.31.1: 1983 – this makes a positive contribution to thermal containment between spaces within a building, as well as for external doors.
• Tested & Proven – It is tested and certified to meet rigorous fire and smoke resistance standards – meeting Approved Documents B. Fire: BS 476-22:1987 & BS EN 1634-1:2008. Smoke: BS 476-31.1: 1983 at ambient temperature. Assessment: CNA/F14171. Acoustic: BS EN ISO 10140-2:2010.
• Continuous sealing at ironmongery points – Its unique design means that whichever way around the product is installed, the seal can always be fitted in the correct place, maintaining the integrity of the acoustic and smoke seal at the ironmongery points.
• Third Party Certification – CERTIFIRE (CF330 & CF341) / BBA 92/2841 / IFC FRPP454
  Highly durable – has achieved over 1,000,000 opening and closing cycles on a full size door assembly.
• Choice of sizes & finishes – sizes to cover both 30 and 60 minute applications. Available in a range of standard colours, with black fins – to blend or contrast with the doorset as required.
• Easy to store – Its unique shape allows the product to be stacked, ensuring minimal storage space and protection of the fins.
• Made in Britain – the DS seal is manufactured using the highest quality materials in Devon.
