  • Patent number: 9010829
    Abstract: Disclosed are various embodiments of expandable barriers. Expandable barriers are typically barriers made from an expandable material and formed to fit within a cavity. After being placed inside a cavity, expandable barriers generally undergo an activation process, where the expandable barrier expands to fill the cavity and create a physical barrier. Using various extrusion processes to form an expandable barrier allows for a reduction in tooling costs, while also allowing more flexible barrier designs. Such designs can be specifically tailored for a particular cavity or cavities to ensure that the barrier fills the cavity after expansion.

  • Patent number: 8444214
    Abstract: Exemplary baffles for inhibiting noise transmission through a pillar structure, and exemplary methods of making the same, are disclosed. An exemplary baffle may include a body configured to be secured in a cavity, the body defining a passage for selectively receiving a line extending through the body. The baffle may further include an expandable material extending substantially about a perimeter of the passage. The expandable material may be configured to expand to seal the cavity about the body. The body may include a flap configured to open to allow the line to extend through the passage. The body may further include a biasing element urging the flap toward a closed position, substantially obstructing the passageway.
