Self-closing thermal and electrical fire protection sheath (1) which has a substantially tubular shape when not subjected to stresses, such that the longitudinal edges (2, 3) overlap to define an opening for the insertion of cables (4), tubes or the like into the sheath (1), in which the sheath (1) has a layered structure, with a first layer (5) consisting of a fabric braided from glass fibre filaments (7) and plastic monofilaments (8) and a second, outer layer (6), in which the second layer (6) is made of silicone, the thickness of said second layer (6) being at least 200 microns. The invention also relates to methods for making said sheath. |
