LAS1212 & LAS1515 Batwing® Acoustic Smoke Seal
The Lorient Batwing® series is primarily designed to contain sound and restrict the spread of medium temperature smoke around hinged door assemblies.
LAS8008 si Drop Seal
A slimline face-fixed automatic drop seal with a curved cover plate for enhanced aesthetics. It features a high efficiency mechanism, which lifts the seal clear of the floor as soon as the door is opened by a few millimetres; resulting in lower door operating forces. Self-levelling on uneven floors, seal height can be adjusted independently of fixing screws.
Key benefits
- Effective acoustic sealing solution that can easily be retrofitted to existing door assemblies.
- Durable flexible elastomeric fin elements are incorporated with the housing to provide acoustic and smoke properties.
- It requires no power connection.Curved cover conceals fixing points.
- Surface mounted application suitable for upgrading existing doors.
- Proven long term reliability.
