The Lorient Batwing® series is primarily designed to contain sound and restrict the spread of medium temperature smoke around hinged door assemblies. Their symmetrical design and unique curved sealing fins provide outstanding performance benefits.

Our newly launched clear Batwing® is also available for that ultra discreet look.

• Highly effective acoustic seal that can be retrofitted to existing door assemblies.
• Low friction curved elastomeric fins spring back to original shape to provide continuous performance.
• Discreetly positioned in frame rebate to provide a fully concealed sealing solution.
• Simple peel-and-stick installation, our aggressive self-adhesive backing is tested on many surfaced to ensure seal longevity.
