Combines internal & external fins with a center fin all in one brush seal.
Additional fins = additional barriers for a tighter seal against the elements.
Can be used in either normal or acoustic applications which require superior performance.
Features & Benefits
- Tests indicate at least a 20% reduction in air infiltration as compared to single center fin.
- Five-Fin and Multi-Hollow bulb seal combinations tested as well as current acoustic seals in the market.
- The Five-Fin construction helps reduce vibration which aids in the acoustical value.
- No binding or breaking during insertion, which increases through-put and leads to reduced waste and lower costs.
- Built in “pile directors” reduce compression set.
- Covered under the AAMA 701-11 VCL testing standard.
- All Five-Fin seals have silicone treated pile fibers to repel moisture.
