The Lorient Curved Fin Batwing acoustic and smoke seal minimises the opening and closing resistance of the door leaf due to its unique, curved fins.

• Flexible elastomeric fin material springs back to original shape to provide ongoing performance and durability in service.
   
• Symmetrical design ensures fins are always in contact with two surfaces of the door leaf, creating an air chamber to provide excellent acoustic properties.
   
• Acoustically tested in accordance with BS EN ISO 10140-1: 2010 +A1: 2012 and proven to meet the requirements of Approved Document B. Will achieve a rating of 31dB Rw when tested on a typical FD30 door assembly, in conjunction with a LAS8001 si threshold seal - no additional perimeter seal required.
   
• Effective smoke seal up to 200°C.
   
• Aggressive self-adhesive backing tested on many surfaces, including MDF.
   
• Variety of colours to blend with door designs.
    
• Tested to 1,000,000 opening and closing cycles on a full size door assembly, without failure.
