The invention relates to an insulation element, in particular for the acoustic insulation of an opening and/or of a cavity in a vehicle or building, having a carrier element and an expendable material. The carrier element has a plurality of through-holes, wherein only one surface of the carrier element is covered at least partially with expandable material, and the expandable material at least partially fills the through-holes. The invention relates furthermore to an insulation element produced therefrom, the use of the same and a method for the acoustic insulation and/or reinforcement of an opening or a cavity in a land, air or water vehicle or in a building.

Insulation element, expanded insulation element, use of same and method for insulation

A baffle is provided that includes at least one carrier and a sealer disposed in a recess. When placed in a cavity, such as a vehicle cavity, sealer also expands into the cavity to seal the cavity. Baffle can be modified by including an insert within carrier to increase the weight, density, and structural rigidity of baffle, without altering the exterior dimensions of baffle. A baffle that includes an insert can be customized based on a particular application, without requiring time-consuming and expensive tooling changes.

Baffle

A baffle is provided that includes a body portion having a first layer and a second layer defining a free space therebetween. A sealer is disposed on the body portion in the space between the first layer and the second layer. The space has a predetermined volume and the sealer is expandable in the space. When placed in a cavity, such as a vehicle cavity, the sealer also expands into the cavity to seal the cavity. The baffle is more light-weight and capable of reducing noise and vibration, especially at higher frequencies than traditional baffles.
