DS acoustic seal, smoke seal & fire door seal
Dual seal (DS) is designed to allow seal continuity at hinge positions. This slim-line seal is fitted into the door edge or frame to restrict the spread of ambient and elevated temperature smoke. When exposed to fire conditions the high performance intumescent core rapidly expands in volume to seal the door perimeter and restrict the passage of fire, toxic gases and hot smoke.
Key benefits
- All-in -one “life safety” seal. Ideal for use in fire engineering solutions to limit the spread of fire and smoke around the edges of doors.
- May be used to improve fire resistance performance of existing door assemblies.
- Low friction elastomeric fins provide excellent acoustic and smoke containment performance as well as contributing to low operating forces.
- Intumescent core protected by a durable thermoplastic sheath.
- Suitable for healthcare applications, the casing and fins feature anti-microbial additives to limit bacterial growth.
- Use in conjunction with a LAS8001si drop seal for a complete life safety door sealing solution.
