Our products help improve the NVH performance at a lower weight than a traditional metal reinforcement. This product is traditionally applied in an interior cavity of the vehicle for structural reinforcement. They can be used to reinforce, frame rails, body cavities or body panels. These products focus on acoustic improvement with expandable cavity seals based on EVA or EPDM. These preformed parts work on a noise absorption principle that blocks the passage of airborne noise in the hollow cavities of the vehicle.
