Acoustic Double Flipper/Twin Fin by Reddiplex (Harmony)

The Harmony® range of perimeter seals have been specifically designed to provide an effective barrier to seal perimeter gaps around pedestrian doorset assemblies, restricting the passage of noise, smoke and air movements. The fitting of such seals will help dramatically improve the effectiveness of the doorset assembly, in terms of noise permeation and minimise smoke and air movement through the perimeter gaps. The Reddiplex Harmony® Twin Fin is designed to be installed between the door rebate and the reveal of the door frame. As the door closes onto the seal, the integral fins compress around the door edges to create a localised “air pocket” effectively bridging the perimeter gap. The product is supplied with a high performance self-adhesive for ease of installation, ideal for new and existing applications.
