Abstract:
1. A method for locally reinforcing or baffling a structure having a hollow cavity, comprising the steps of: i) providing an insert including a generally flat carrier having a first face and an opposing second face each terminating at a peripheral edge, wherein the carrier: ii) flexing the insert during insertion into the cavity to be locked into place within the cavity via the at least one integrally formed flexible attachment; iii) at least partially rotating the at least one integrally formed flexible attachment, so that after such rotating the first face and the second face project generally transversely into the cavity and a gap is defined between the peripheral edge and a wall of the structure; iv) heating the thermally expandable polymeric material to cause it to expand and seal the gap that exists between the peripheral edge and the wall of the structure; thereby separating the hollow cavity into separate chambers on either side of the insert.
