The Benefits of the DS Seal: A Multifunctional Fire Seal for doors
When it comes to sealing solutions for doors, Lorient's DS Seal stands out as a top choice for architects, builders, and construction professionals. With its innovative design and exceptional performance, the DS Seal offers a multitude of benefits that enhance both the functionality and efficiency of a door assembly. Let's explore some of the key advantages of Lorient's DS Seal:
Fire & Smoke Protection
In the event of a fire, the intumescent material in the DS seal will expand 5 – 10 times its original size & seal the gaps between the fire door leaf and frame around the door, containing the spread of fire & hot smoke. The fins on the DS seal restrict the movement of cold smoke around a building – giving people time to escape and reducing property damage.
Acoustic Containment
Lorient’s fin seal technology has been proven to deliver superior acoustic performance – meeting the requirements of Approved Document E.
