An impermeable flexible tube for protecting electrical cables from radiant heat comprising: an inner textile fabric tube layer coated with a flexible polymeric material to achieve at least external surface impregnation of said inner textile fabric tube layer; and an outer, reinforcement-free layer of a flexible polymeric material, wherein the polymeric material used to coat the inner textile fabric layer contains non-metallic opacifiers, and the polymeric material of the outer layer is at least translucent and contains randomly dispersed reflective metal particles defining a first means to reflect radiant heat in which some radiant heat may pass between said metal particles, and said non-metallic opacifiers defining a second means to stop radiant heat passing said first means and thereby minimize radiant heat transfer to the electrical cables.
