The Lorient Batwing Doorset Pack is a premium acoustic and smoke sealing system designed for internal doors, fire doors and architectural openings across the UK. Trusted by installers in Halifax, Huddersfield, Leeds and Manchester, it offers up to Rw 41dB acoustic performance, Certifire approval and long-term durability for both single and double leaf doors.
The Lorient Batwing Doorset Pack is a proven acoustic and smoke sealing system built for reliable performance on internal doors, including acoustic tested internal doors, internal fire doors, and commercial door sets. Designed with a clever double-fin profile, the Batwing seal provides a tight, flexible barrier that reduces smoke movement and significantly improves acoustic control—without making the door difficult to open or close.
Each seal is manufactured with a co-extruded rigid PVC back and flexible elastomeric fins. This gives the Batwing its distinctive spring-back action, allowing the fins to compress smoothly as the door closes and then return to shape after every use. Because of this, the system maintains consistent performance over time and has been durability-tested to 100,000 cycles.
The Batwing system is tested to BS EN ISO 10140-2:2010, achieving acoustic performance up to Rw 41dB when installed as part of a complete acoustic door solution. It also contributes to smoke, draught and light containment, making it suitable for residential, commercial and public buildings.
Backed by Certifire approval (CF5179) and compliant with BS 476-31.1:1983 and BS EN 1634-3:2004 for smoke control, it’s a trusted choice for contractors and door manufacturers seeking a certified sealing solution.
