Abstract
Cavities are partially or entirely filled with a polymer foam. A flexible, porous mesh tube is introduced into the cavity. The mesh tube has a volume smaller than that of the cavity and has openings. A foamable liquid mixture is introduced into the mesh tube. Despite the presence of the openings, the foamable liquid mixture does not pass through the openings in the mesh tube. The captured liquid composition then expands. As the composition expands, it flows through the openings in the mesh tube and makes contact with the walls of the cavity. After curing, a polymer foam is obtained which adheres to the cavity walls.
