Hi guys,
Interesting question. I don't know the answer either, but maybe I can offer a guess? I'm a chemical engineer, and industry uses process tanks with a heat transfer jacket (for heating or cooling) on the outside wall of the vessel. To conserve energy, the jacket is usually insulated, and the insulation is then protected with a sheet metal sheath on the outside. The resulting shape looks remarkably similar to a thermal sleeve.
OK, so what? Well, typically the insulation sheathing has holes drilled (called weep holes) into the bottom of the sheathing to allow any water condensate to drain away from the insulation layer, thus minimizing a potential corrosion issue. Additionally, the holes let the insulation "breathe" as the metal tank heats up and cool down, thus maintaing an equal pressure in the insulation layer. I have never put my hand on the barrel of a 105 after several rounds, but...
Just a dumb engineer's guess...HTH.
