The 3084 insert is a high-performance neoprene seal specifically designed for use with the SmartSeal WBC contact strip. Installed between the weatherboard and aluminium threshold plate, it provides reliable weatherproofing, draught exclusion, acoustic insulation, and light containment at the base of doors.
Manufactured from durable, flexible neoprene, the 3084 delivers excellent compression and recovery, ensuring long-term sealing performance in both internal and external applications. It can be easily fitted into the threshold plate and replaced without removing the aluminium section, making it ideal for maintenance, refurbishment, and retrofit projects.
The 3084 insert is suitable for doors subject to regular traffic and varying environmental conditions, particularly where a weather-tight seal is required. When used with the SmartSeal WBC contact strip and compatible weatherboards, it forms part of a complete sealing system that helps prevent water ingress beneath the door leaf.
Common applications include studios, music rooms, interview rooms, photographic darkrooms, and buildings incorporating gas flood fire suppression systems, where enhanced acoustic and light control are essential.
When installed with SmartSeal threshold plates, the 3084 supports low-profile threshold solutions compliant with Part M Building Regulations, providing improved accessibility without compromising sealing performance.
